Preface

Welcome to the Adobe Photoshop® File Format Specification!

This document is the detailed specification of the Adobe Photoshop file format and other pertinentfile formats that Adobe Photoshop reads and writes.

Audience

This document is provided for 3rd parties to read and write the Photoshop native file format.This document does not explain how to interpret the data. This document describes the format of the data only.

What Is In This Document

This document has three chapters:

The Photoshop File Formatdescribes the Photoshop PSD and PSB native file format indetail.

Other Document File Formatsdiscusses Photoshop's handling of the EPS and TIFF file formats,which Photoshop can also create and read.

Additional File Formatsdescribes the formats of other files used by Photoshop to store information about such items as colors,contours, curves, levels and so forth.

For more information about file formats, you may wish to consult the Encyclopedia of Graphics File Formats by James D. Murray & William vanRyper (1994, O'Reilly &Associates, Inc., Sebastopol, CA, ISBN 1-56592-058-9).

What Is NOT In This Document

This document does not have any information regarding the PSDC (Photoshop Cloud Document) thatwas introduced in November of 2019. That format, at this time, is private. This link will give you moreinformation about Photoshop Cloud Documents.

SDK User to User Forum

The Adobe forums web page, http://www.adobe.com/support/forums, is also availble for discussion of SDK issues. From thepage above follow the Photoshop link and then the Adobe Photoshop Developers link.

The Photoshop FileFormat

Introduction

This chapter discusses the Photoshop native file format

*Photoshop file types*
OS	Filetype/extension
Mac OS	8BPS
Windows	.PSD

Large Document Format

The Large Document Format (8BPB/PSB) supports documents up to 300,000 pixels in anydimension. All Photoshop features, such as layers, effects, and filters, are supported by the PSB format.The PSB format is identical to the Photoshop native format in many ways. This document will cover thedifferences found in the PSB format by donating a **PSB** marker.

Windows

All data is stored in big endian byte order. On the Windows platform, you must byte swapshort and long integers when reading or writing.

Mac OS

For cross-platform compatibility, all information needed by Photoshop is stored in the datafork. For interoperability with other Macintosh applications, however, some information is duplicated inresources stored in the resource fork of the file:

For compatibility with image cataloging applications, the 'pnot'resource id 0 contains references to thumbnail, keywords, and caption information stored in other resources.

The thumbnail picture is stored in a 'PICT' resource, the keywordsare stored in 'STR#' resource 128 and the caption text is stored in 'TEXT' resource 128. For more information on the format of these resources see Inside Macintosh: QuickTime Components and the Extensis FetchAwareness Developer's Toolkit .

Photoshop also creates 'icl8' -16455 and 'ICN#'-16455 resources containing thumbnail images which will be shown in the Mac OS Finder.

All of the data from Photoshop's File Info dialog is stored in 'ANPA'resource 10000. The data in this resource is stored as an IPTC-NAA record 2.For more information on theformat of this resource, see the documents in the IPTC folder of the Documentation folder.

Photoshop File Format

The Photoshop file format is divided into five major parts, as shown in the Photoshop file structure. The Photoshop fileformat has many length markers. Use these length markers to move from one section to the next. The lengthmarkers are usually padded with bytes to round to the nearest 2 or 4 byte interval.

Photoshop file structure

File header (File HeaderSection).

Color mode data (Color ModeData Section)

Image resources (ImageResources Section)

Layer and mask information (Layer and Mask Information Section)

Image data (Image DataSection).

The file header has a fixed length; the other four sections are variable in length.

When writing one of these sections, you should write all fields in the section, as Photoshopmay try to read the entire section. Whenever writing a file and skipping bytes, you should explicitly writezeros for the skipped fields.

When reading one of the length-delimited sections, use the length field to decide when youshould stop reading. In most cases, the length field indicates the number of bytes, not records, following.

The values in "Length" column in all tables are in bytes.

All values defined as Unicode string consist of:

A 4-byte length field, representing the number of UTF-16 code units in the string (notbytes).

The string of Unicode values, two bytes per character and a two byte null for the end ofthe string.

File Header Section

The file header contains the basic properties of the image.

*File header section*
Length	Description
4	Signature: always equal to '8BPS' . Do not try to read the fileif the signature does not match this value.
2	Version: always equal to 1. Do not try to read the file if the version does not matchthis value. (PSB version is 2.)
6	Reserved: must be zero.
2	The number of channels in the image, including any alpha channels. Supported range is1 to 56.
4	The height of the image in pixels. Supported range is 1 to 30,000. (PSB max of 300,000.)
4	The width of the image in pixels. Supported range is 1 to 30,000. (PSB* max of 300,000)
2	Depth: the number of bits per channel. Supported values are 1, 8, 16 and 32.
2	The color mode of the file. Supported values are: Bitmap = 0; Grayscale = 1; Indexed= 2; RGB = 3; CMYK = 4; Multichannel = 7; Duotone = 8; Lab = 9.

Color Mode Data Section

The color mode data section is structured as follows:

*Color mode data section*
Length	Description
4	The length of the following color data.
Variable	The color data.

Only indexed color and duotone (see the mode field in the File header section) have color mode data.For all other modes, this section is just the 4-byte length field, which is set to zero.

Indexed color images: length is 768; color data contains the color table for the image, innon-interleaved order.

Duotone images: color data contains the duotone specification (the format of which is notdocumented). Other applications that read Photoshop files can treat a duotone image as a gray image, and justpreserve the contents of the duotone information when reading and writing the file.

Image Resources Section

The third section of the file contains image resources. It starts with a length field, followedby a series of resource blocks.

*Image resources section*
Length	Description
4	Length of image resource section. The length may be zero.
Variable	Image resources (ImageResource Blocks ).

Image Resource Blocks

Image resource blocks are the basic building unit of several file formats, includingPhotoshop's native file format, JPEG, and TIFF. Image resources are used to store non-pixel data associatedwith images, such as pen tool paths.

They are referred to as resource blocks because they hold data that was stored in theMacintosh's resource fork in early versions of Photoshop.

The basic structure of image resource blocks is shown in the Image resource block. The last field isthe data area, which varies by resource type. The makeup of each resource type is described in the followingsections.

*Image resource block*
Length	Description
4	Signature: '8BIM'
2	Unique identifier for the resource. Image resource IDs contains a listof resource IDs used by Photoshop.
Variable	Name: Pascal string, padded to make the size even (a null name consists of twobytes of 0)
4	Actual size of resource data that follows
Variable	The resource data, described in the sections on the individual resource types. Itis padded to make the size even.

Image Resource IDs

Image resources use several standard ID numbers, as shown in the Image resource IDs. Not all file formatsuse all ID's. Some information may be stored in other sections of the file.

For those resource IDs that have been added since Photoshop 3.0. the entry indicates theversion in which they were introduced, e.g. ( Photoshop 6.0).

The following sections describe some of the resource formats in more detail.

Grid and guides resource format

Photoshop stores grid and guides information for an image in an image resource block. Each ofthese resource blocks consists of an initial 16-byte grid and guide header, which is always present,followed by 5-byte blocks of specific guide information for guide direction and location, which are presentif there are guides ( fGuideCount > 0) .

*Grid and guide header*
Length	Description
4	Version ( = 1)
8	Future implementation of document-specific grids (4 bytes horizontal, 4 bytesvertical). Currently, sets the grid cycle to every quarter inch, i.e. 576 for both horizontal &vertical (at 72 dpi, that is 18 * 32 = 576)
4	fGuideCount : Number of guide resource blocks (can be 0).

*Guide resource block*
Length	Description
4	Location of guide in document coordinates. Since the guide is either vertical orhorizontal, this only has to be one component of the coordinate.
1	Direction of guide. VHSelect is a system type of unsignedchar where 0 = vertical, 1 = horizontal.

Grid and guide information may be modified using the Property suite. See the Callbackschapter in Photoshop API Guide.pdf for more information.

Thumbnail resource format

Adobe Photoshop (version 5.0 and later) stores thumbnail information for preview display inan image resource block that consists of an initial 28-byte header, followed by a JFIF thumbnail in RGB(red, green, blue) order for both Macintosh and Windows.

Adobe Photoshop 4.0 stored the thumbnail information in the same format except the datasection is BGR (blue, green, red). The 4.0 format is at resource ID 1033 and the 5.0 format is at resourceID 1036.

*Thumbnail resource header*
Length	Description
4	Format. 1 = kJpegRGB . Also supports kRawRGB (0).
4	Width of thumbnail in pixels.
4	Height of thumbnail in pixels.
4	Widthbytes: Padded row bytes = (width * bits per pixel + 31) / 32 * 4.
4	Total size = widthbytes * height * planes
4	Size after compression. Used for consistency check.
2	Bits per pixel. = 24
2	Number of planes. = 1
Variable	JFIF data in RGB format. For resource ID 1033 the data is in BGR format.

Color samplers resource format

Adobe Photoshop (version 5.0 and later) stores color samplers information for an image inan image resource block that consists of an initial 8-byte color samplers header followed by a variablelength block of specific color samplers information.

*Color Samplers header*
Length	Description
4	Version ( = 1, 2 or 3)
4	Number of color samplers to follow. See See Color Samplers resource block.

*Color Samplers resource block*
Length	Description
4	Version of color samplers, 1 for version 3. ( Version 3 only ) .
8	The horizontal and vertical position of the point (4 bytes each). Version 1 is afixed value. Version 2 is a float value.
2	Color Space: enum { colorCodeDummy = -1, RGB, HSB, CMYK, Pantone, Focoltone,Trumatch, Toyo, Lab, Gray, WideCMYK, HKS, DIC, TotalInk, MonitorRGB, Duotone, Opacity, Web,GrayFloat, RGBFloat, OpacityFloat};
2	Depth ( Version 2 only )

Path resource format

Photoshop stores the paths saved with an image in an image resource block. These resourceblocks consist of a series of 26-byte path point records, so the resource length should always be amultiple of 26.

Photoshop stores its paths as resources of type 8BIM , with IDs inthe range 2000 through 2997. These numbers should be reserved for Photoshop. The name of the resource isthe name given to the path when it was saved.

If the file contains a resource of type 8BIM with an ID of 2999, thenthis resource contains a Pascal-style string containing the name of the clipping path to use with thisimage when saving it as an EPS file.4 byte fixed value for flatness and 2 byte fill rule. 0 = same fill rule, 1 =even odd fill rule, 2 = non zero winding fill rule. The fill rule is ignored byPhotoshop.

The path format returned by GetProperty() call is identical to whatis described below. Refer to the IllustratorExport sample plug-in code to seehow this resource data is constructed.

Path points

All points used in defining a path are stored in eight bytes as a pair of 32-bitcomponents, vertical component first.

The two components are signed, fixed point numbers with 8 bits before the binary point and24 bits after the binary point. Three guard bits are reserved in the points to eliminate most concernsover arithmetic overflow. Hence, the range for each component is 0xF0000000 to 0x0FFFFFFF representing a range of -16 to 16. The lower bound is included, but not theupper bound.

This limited range is used because the points are expressed relative to the image size. Thevertical component is given with respect to the image height, and the horizontal component is given withrespect to the image width. [ 0,0 ] represents the top-left corner of the image;[ 1,1 ] ([ 0x01000000,0x01000000 ]) represents thebottom-right.

In Windows, the byte order of the path point components are reversed; you should swap thebytes when accessing each 32-bit value.

Path records

The data in a path resource consists of one or more 26-byte records. The first two bytes ofeach record is a selector to indicate what kind of path it is. For Windows, you should swap the bytesbefore accessing it as a short.

*Path data record types*
Selector	Description
0	Closed subpath length record
1	Closed subpath Bezier knot, linked
2	Closed subpath Bezier knot, unlinked
3	Open subpath length record
4	Open subpath Bezier knot, linked
5	Open subpath Bezier knot, unlinked
6	Path fill rule record
7	Clipboard record
8	Initial fill rule record

The first 26-byte path record contains a selector value of 6, path fill rule record. Theremaining 24 bytes of the first record are zeroes. Paths use even/odd ruling. Subpath length records,selector value 0 or 3, contain the number of Bezier knot records in bytes 2 and 3. The remaining 22 bytesare unused, and should be zeroes. Each length record is then immediately followed by the Bezier knotrecords describing the knots of the subpath.

In Bezier knot records, the 24 bytes following the selector field contain three path points(described above) for:

the control point for the Bezier segment preceding the knot,

the anchor point for the knot, and

the control point for the Bezier segment leaving the knot.

Linked knots have their control points linked. Editing one point modifies the other topreserve collinearity. Knots should only be marked as having linked controls if their control points arecollinear with their anchor. The control points on unlinked knots are independent of each other. Refer tothe Adobe Photoshop User Guide for more information.

Clipboard records, selector=7 , contain four fixed-point numbers forthe bounding rectangle (top, left, bottom, right), and a single fixed-point number indicating theresolution.

Initial fill records, selector=8 , contain one two byte record. Avalue of 1 means that the fill starts with all pixels. The value will be either 0 or 1.

Slices resource format

Adobe Photoshop 6.0 stores slices information for an image in an image resource block.

Adobe Photoshop 7.0 added a descriptor at the end of the block for the individual sliceinfo.

Adobe Photoshop CS and later changed to version 7 or 8 and uses a Descriptor to defined theSlices data.

*Slices header for version 7 or 8*
Length	Description

Vanishing point resource format

Adobe Photoshop CS2 (9.0) and later stores vanishing point information for an image in animage resource block. The entire resource is a string with an id of 'tnaF' on Windows and 'FaNt' on theMacintosh. The structure of the resource is as follows:

Vocabulary:

Relation - a set of related planes.

Root Plane - the first plane in a relation.

Calibration Order - an ordering of the planes in a relation starting with the root plane,depth first, recursive traversal of the planes that are attached to the given plane.

Basics:

A planes area is represented as a clipped area of vanish rays. A Ray defines one of thevirtual sides of the plane's area. A Ray's structure keeps track of information needed for tearing off andorientation issues. Parallel rays must point at the same VPID. A Primary ray's origin represents the pointon the plane that is farthest from both VPs. The two primary rays share an origin.

version = 101

number of relations to follow.

-- for each relation--

grid resolution for the root plane

number of planes to follow

-- for each plane in calibration order--

ID of the plane

ID of the plane that calibrates this plane 0 if none

-- for 4 rays --

origin position of the ray. Point

VP location - must be consistent across all planes in the relation unless it is anendpoint. Point

true if the VP location is an endpoint

ID that this ray points at.

Ray DI (see below)

++++++++++++++++++++

I/O appendix

Point - two doubles; h endl, v endl

VPID - int (enum value) 0,1,2 identifing 1 of 3 possible VPs

RayID - 1, One of the primary rays directly connected to the shared origin

3, a non-primary ray parallel to 7

5, a non-primary ray parallel to 1

7, One of the primary rays directly connected to the shared origin .

Layer and Mask Information Section

The fourth section of a Photoshop file contains information about layers and masks. Thissection of the document describes the formats of layer and mask records.

The complete merged image data is not stored here. The complete merged/composite image residesin the last section of the file. See See ImageData Section. If maximize compatibility is unchecked then the merged/composite is not created and thelayer data must be read to reproduce the final image.

See Layer and mask informationsection shows the overall structure of this section. If there are no layers or masks, this section isjust 4 bytes: the length field, which is set to zero. (**PSB** length is 8 bytes

'Layr', 'Lr16' and 'Lr32' start at See Layer info. NOTE: The length of the section may already be known.)

Transparency shapes layer (Photoshop 7.0)

Key is 'tsly' . Data is as follows:

*Transparency shapes layer*
Length	Description
1	1: the transparency of the layer is used in determining the shape of the effects.This is the default for behavior like previous versions. 0: treated in the same way as fill opacity including modulating blend modes,rather than acting as strict transparency. Using this feature is useful for achieving effects that otherwise would requirecomplex use of clipping groups.

*Layer mask as global mask*
Length	Description
1	1: the layer mask is used in a final crossfade masking the layer and effectsrather than being used to shape the layer and its effects. This behavior was previously tied to the link status flag for the layer mask. (Anunlinked mask acted like a flag value of 1, a linked mask like 0). For old files that lack this key,the link status is used in order to preserve compositing results.
3	Padding

The RLE compressed data follows, witheach scan line compressed separately. The RLE compression is the same compression algorithm used by theMacintosh ROM routine PackBits , and the TIFF standard. 2 = ZIP without prediction 3 = ZIP with prediction.
Variable	The image data. Planar order = RRR GGG BBB, etc.

Additional FileFormats

In addition to documents that the user creates in Adobe Photoshop (discussed in See The Photoshop File Format), there are anumber of additional files used by Photoshop to store information about such items as colors, contours, curves,levels and so forth. These are known as load files.

This chapter describes the format of each load file. Some of the files can saved by the user;others are load only, as indicated in the sections.

Each file has a unique file type and file extension associated with it. Photoshop for Macintoshrecognizes either, but does not require the use of the extension. In the file dialogs, Photoshop for Windowslooks for files with the given file extension automatically; this can be overridden.

Under Mac OS, all information is stored in the data forks of Photoshop's load files. The filesare completely interchangable with Windows or any other platform.

Consistent byte ordering is required across platforms when reading and writing load files.Photoshop stores multi-byte values with the high-order bytes first, (big-endian), as on Mac OS., which is theopposite of Windows' standard byte order.. For more information, see "Macintosh and Windowsdevelopment" in chapter 2 of Photoshop API Guide.pdf .

Arbitrary Map

Arbitrary Map files are accessed by means of the Curves dialog ( loadonly ).

*Arbitrary map file types*
OS	Filetype/extension
Mac OS	8BLT
Windows	.AMP

There is no version number written in the file.

The files are an even multiple of 256 bytes long. Each 256 bytes is a lookup table, where:

The first byte of the table corresponds to byte zero of the image.

The last byte of the table corresponds to byte 255 of the image.

A NULL table that has no effect on an image is a linear table of bytesfrom 0 to 255.

If the file has one table, it is applied to the image's channels according to these priorities:

If the image has a master composite channel, the table is applied to it. If not, then:

If the image has a single active channel, the table is applied to it. If not, then:

If the image has no composite channel and more than one active channel, the table is notapplied.

If the file has exactly three tables, it is applied to the image's channels according to thesepriorities:

The tables are assumed to represent RGB lookups. They are applied to the first three channelsin the image, leaving the master composite untouched. Or:

If the image has a single active channel, the tables are converted to grayscale and theresult is applied to the active channel. Or:

The first table is treated as a master. The remaining tables are applied to the imagechannels in turn (second table is applied to first channel, third table is applied to second channel, etc.).

Single active channels

Photoshop handles single active channels in a special fashion. When saving a map applied to asingle channel, only one table is written to the file. Similarly, when reading a file for application to asingle active channel, the master table is the one that will be used on that channel. This allows easyapplication of a single file to both composite and grayscale images.

CMYK Setup

CMYK settings files are accessed in Photoshop's Color Settings dialog (loadonly) .

Curves files can also be loaded into any of Photoshop's transferfunction dialogs, such as the Duotone Curve dialog from within Duotone Options, and Print transfer dialog.Curves are saved as .ATF and .ACV files.

When loaded into a transfer function dialog, only the first curve in a Curves file is used.

*Curves file types*

*Curves file format*
Length	Description
2	Version ( = 1 or = 4)
2	Version 1 = bit map of curves in file Version 4 = count of curves in the file
The following is the data for each curve specified by count above
2	Count of points in the curve (short integer from 2...19)
point count * 4	Curve points. Each curve point is a pair of short integers where the first number isthe output value (vertical coordinate on the Curves dialog graph) and the second is the input value. Allcoordinates have range 0 to 255. See also See Null curves below.

Null curves

A NULL curve (no change to image data) is represented by the followingfive-number, ten-byte sequence in a file:

2 0 0 255 255

Displaying ink percentages

Photoshop allows the option of displaying ink percentages instead of pixel values; this is adisplay option only and the internal data is unchanged, with 100% ink equal to image data of 0 and 0% inkequal to image data of 255.

Curves data order

The first curve is a master curve that applies to all the composite channels (RGB) when incomposite image mode.

The remaining curves apply to the active channels in order: curve two applies to channel one,curve three applies to channel two, etc., up until curve 17, which applies to channel 16.

Indexed color

The exception to the normal order, and the reason there are up to 19 curves, is when the modeis Indexed color. In this case:

The first curve is a master curve.

The next three curves are created for the Red, Green, and Blue portions of the image's colortable, and they are applied to the first channel.

The remaining curves apply to any remaining alpha channel that is active: for instance, ifchannel two is active, curve five applies to it; if channel three is active, curve six applies to it, etc., upuntil curve 19, which applies to channel 16.

Single active channels

Photoshop handles single active channels in a special fashion. When saving the curves appliedto a single channel, the settings are stored into the master curve, at the beginning of the file. Similarly,when reading a curves file for application to a single active channel, the master curve is the one that willbe used on that channel. This allows easy application of a single file to both RGB and grayscale images.

29 * 10	29 sets of level records, each level containing 5 short integers (see See Level record structure).

*Level record structure*
Length	Description
2	Input floor (0...253)
2	Input ceiling (2...255)

2	Output ceiling (0...255)
2	Gamma. Short integer from 10...999 representing 0.1...9.99. Applied to all imagedata.

Level record sets order

The first set of levels is the master set that applies to all of the composite channels (RGB)when in composite image mode.

The remaining sets apply to the active channels individually; set two applies to channel one,the set three to channel two, etc., up until set 25, which applies to channel 24.

Sets 28 and 29 are reserved and should be set to zeros.

Indexed color

The exception to the normal order is when the mode is Indexed:

The first set is a master set.

The next three sets are created for the Red, Green, and Blue portions of the image's colortable, and they are applied to the first channel.

The remaining sets apply to any remaining alpha channels that are active: for instance, ifchannel two is active, set five applies to it; if channel three is active, set six applies to it, etc., upuntil channel 27, which applies to channel 24.

Sets 28 and 29 are reserved and should be set to zeros.

Single active channels

Photoshop handles single active channels in a special fashion. When saving the levelsapplied to a single channel, the settings are stored into the master set, at the beginning of the file.Similarly, when reading a levels file for application to a single active channel, the master levels are theones that will be used on that channel. This allows easy application of a single file to both RGB andgrayscale images.

(333333 +256)*3	If file contains CMYK->Lab table, this section contains Lab colors for333333+256 CMYK colors. The Lab colors are written in interleaved order, one byte per component. SeeSee Generating CMYK source colorsbelow.
1	Boolean. True if gamut table follows.
1	If entry above is false , this byte will not be present. If true, this byte should be set to 1 for compatibility.
(((333333L)+7)>>3) if gamut table present, zero otherwise	Gamut table, if present. The gamut table is a bit table indexed in the same way asthe Lab->CMYK table with the high bit of the first byte at index 0. See See Testing for bits in the gamuttable below.

Generating Lab source colors

The Lab colors that are the source colors can be generated from the Lab->CMYK table with the following routine:

for (i = 0; i < 33; i++)

for (j = 0; j < 33; j++)

for (n = 0; n < 33; n++)

{

L = Min (i * 8, 255);

a = Min (j * 8, 255);

b = Min (n * 8, 255);

}

Generating CMYK source colors

The CMYK colors that are the source colors can be generated from the CMYK->Lab table with the following routine:

for (i = 0; i < 33; i++)

for (j = 0; j < 33; j++)

for (n = 0; n < 33; n++)

{

c = Min (i * 8, 255);

m = Min (j * 8, 255);

y = Min (n * 8, 255);

k = 255;

}

for (i = 0; i < 256; i++)

{

c = 255;

m = 255;

y = 255;

k = i;

}

Testing for bits in the gamut table

To test the bit at bitIndex , use table:

([bitIndex >> 3] & (0x0080 >> (bitIndex & 0x07))) != 0.

bitIndex itself is calculated in the same way you would calculate anindex into the Lab->CMYK table.

A result of 1 indicates that the color is in gamut and 0 indicates that it is out of gamut.

事前処理
/Users/Shared/AdobeGCInfo
/Users/Shared/AdobeGCData　この２つのフォルダを任意の場所に移動

１：Creative Cloud desktop appログアウト
２：Acrobatがログアウトしているのを確認
３：Bridgeがログアウトしているのを確認
３x：Elements系APP利用時はElementsAPPもログアウト
-->これでAdobe系の全アプリからログアウト

４：Camera Raw 16.4 installer上書きインストール
https://www.adobe.com/go/acr_installer_mac
５：Adobe Digital Negative Converter上書きインストール
https://www.adobe.com/go/dng_converter_mac_jp
６：Creative Cloud desktop appをアップデート
Appleシリコン版
https://ccmdls.adobe.com/AdobeProducts/StandaloneBuilds/ACCC/ESD/6.3.0/207/macarm64/ACCCx6_3_0_207.dmg
留意：AGSはONでインストール

７：ここで絶対！機材の電源をOFF-ONでの再起動
８：Bridge起動
９：Bridgeから呼び出されたログイン画面でAdobeID：Aでログイン
-->最重要ここでCamera Rawを呼び出さない事
10：Creative Cloud desktop appを起動してBridgeが最新なのを確認
-->アップデートかインストールが出てれば実行する
11：Creative Cloud desktop appを起動してCamera Rawが最新なのを確認
-->アップデートかインストールが出てれば実行する
ここで初めて
11：BridgeからCamera Rawを呼び出せるか？確認

こんな流れかな？と思います。

Bridgeからのログインログアウトはここ
