Question About Tag for original image (Pentax K-x)

[mblanc]

Hello,

Is there a tag (I am using a Pentax K-x) to identify the original image that a file from?  In other words, if I start with a raw image, then develop it to a jpeg, and then apply filters, cropping, etc to the jpeg, I have three or more images, all from the same shutter click.  Is there any way to tie these three together?

Thanks

If your developing software preserves the MakerNote information, then you could use the ShutterCount tag to do this.

Thanks, Phil - that is perfect.  And thanks for developing this tool.

Phil, I have a follow-up question.  I know you can use a name wildcard to run the tool against multiple files - but can you match by tag instead of name - ie run against all files where ShutterCount = 1234?

Thanks again

Yes.  Add -if "$shuttercount == 1234" to the command.

(note: use double quotes as above in Windows, or single quotes in Mac/Linux)
