MAX_DigiCam.dll Extension for MyAlbum
======================================
V2.3 - DigitalMatrix
This is a MAX (MyAlbum eXtension) file that adds features to the MyAlbum application.
It extracts image information from EXIF/JPG files and can be useful to owners
of digital still cameras.
Many digital cameras create image files that store information about the image
and the camera that took it. Information about shutter speed, aperture, focal length
is typically included.
With this MAX, MyAlbum will add these information to the album when reading the image.
Installation
------------
Copy the MAX_DigiCam.dll file to the folder where the MyAlbum application is located.
Start MyAlbum and choose the File|Application setup menu item.
Select the MAX tab. Click the Add button and select the MAX_DigiCam.dll file.
The Loaded extensions list should then display the line:
Digital still camera image information extractor
The MAX is ready to use!
Usage
-----
For this MAX to work you should define Custom Fields in your album before adding
images to it. You can use the 'JPEG/Exif' template to create them.
MAX_DigiCam.dll will extract the following information:
Custom field Type Description
---------------------------------------------------------
Date Date Date the picture was taken
Time Time Time the picture was taken
Shutter String Shutter speed
Aperture String Aperture of the lens
Flash String Flash was used or not
Zoom String Focal length used
ImageDescription String Image Description
UserComment String User Comment (ASCII only)
Title String XP Title
Comment String XP Comment
Author String XP Author
Keywords String XP Keywords
Subject String XP Subject
You can customize the names of the Custom Fields used: for instance, you will want
to use 'Date taken' instead of just plain 'Date'.
To do so, open the MAX manager in MyAlbum, select the MAX and click the 'Setup'
button. In the dialog box, you can edit the names of the custom fields that the
MAX will put information in.
Remember that the name specified in the Setup box and the actual name of the
Custom Field must match exactly.
Extracting other fields (Exif)
------------------------------
You can extract other fields from an Exif file (Model, ExposureBias,...).
Note than a specific field may not be generated by a given camera, check
first that your camera is generating the information you're requesting.
To do this:
1- Create, in the MyAlbum folder, a text file named "MAX_DigiCam.ini"
2- For each field you want to extract, write a section using the following
format:
[<Tag#>]
Type=<Type>
Field=<Field name>
with Tag#: the tag number (Exif field identifier) in hexadecimal (0xHHHH notation).
Type: the type of the tag. Ascii, short, long and rational
values are supported:
. 2 = ASCII
. 3 = SHORT A 16-bit (2-byte) unsigned integer
. 4 = LONG A 32-bit (4-byte) unsigned integer
. 5 = RATIONAL
. 9 = SIGNED LONG
. 10 = SIGNED RATIONAL
3- For field with discrete values, it is possible to define plain text
values that will be used instead of the numerical values.
For instance:
1=Manual control
2=Program normal
3=Aperture priority
4=Shutter priority
4- Save the file and restart MyAlbum
5- Open your album and add the new fields to the currently defined Custom
Fields. Use **exactly** the same name as in the .ini file (Field= lines)
and use the "Text" type.
6- To make the values of the new fields appear for pictures already in the
album, right-click the thumbnail and choose the "Update thumbnail"
command.
Examples:
* For extracting the "ExposureBiasValue" field (that is the exposure
compensation), add the following section to the INI file:
[0x9204]
Type=10
Field=ExposureBiasValue
* For extracting the 35mm focal length equivalent:
[0xA405]
Type=3
Field=Focal length
* For extracting the "Metering Mode" and give each value a more meaningful text:
[0x9207]
Type=3
Field=Metering Mode
0=Unknown
1=Average
2=Center weighted average
3=Spot
4=Multi-spot
5=Patern
6=Partial
255=Other
Notes:
- Get a copy of the Exif specifications that lists all the available fields.
- Use a software like ExifRead (from TawbaWare.com) or Exifer
(http://www.exifer.friedemann.info) to see which fields are available in
your pictures.
- Comments can be added to the MAX_DigiCam.ini file: start the line with a ;
character.
- You can access the MAX_DigiCam.ini file from the "DigiCam MAX Setup" screen:
click the "OK" button while holding the "Ctrl" and the "Shift" keys down.
Supported cameras
-----------------
MAX_DigiCam.dll should work with pictures taken by any camera that produces JPEG/Exif
files. Nikon, Minolta, Olympus, Fuji, Ricoh, Kodak and Toshiba cameras use this
format. It also works with older cameras that produce App-12 files (some Agfa,
Epson, Olympus and Sanyo cameras).
