Removing all EXIF but keeping PWP comments in a workflow

Post by tomczak »

Is there a way to remove all in-camera EXIF data but keep those added in Comments widget when saving a JPG in a workflow?

I can add comments in Comments widget and exclude JPG comments in Save widgets, but then no comments are saved. The reason why this may be useful is that I don't need all the in-camera EXIF data when producing a JPG for the web, but still would like to include Author, Copyright and Description metadata.

Cheers!

Saving comments during Jpeg save is an all or nothing operation. So if you saved a Jpeg without comments and then added whatever comments you wanted and saved again with comments, you should get the results you want. You might want to do one or both operations within a workflow.

For small JPGs for the web, EXIF data from the camera take sometimes half of the file size - deleting all EXIF when saving JPG makes sense here. But after deleting all in-camera EXIF, I'd like to add Author, Copyrights, and Description.

One way of doing that is to save JPGs with no EXIF, then reopen those JPGs in another workflow and add User's comment and save JPGs (this time with EXIF) again. But that compresses JPGs twice.

Another way is to save JPGs without EXIF, then go to Browse, select all JPGs and add Keywords - that should add Artist, Copyright and Description to JPGs without opening them to several images at once. The problem is that Keywords seems to scramble the EXIF fields (the comments don't go to the fields they should and are chopped up in the wrong spots).

In either case, removing all EXIF is only possible when saving JPGs - I don't know of a way to remove metadate from e.g. TIFF. Would it be useful to have such option in a workflow (for example in File Comments widget - a checkbox or similar that would allow to delete e.g. all metadata from the image before writing any user's comments to it). I think it would be quite flexible.

For the present program version [v7.0.12] one could:...

Workflow 1:
INPUT: Full Size TIFF [48-bit sRGB colors with Comments/Exif] -> RESIZE: to desired web pixel size -> SHARPEN -> OUTPUT: as a BMP file type in a Folder [BMP does not support meta data]

Workflow 2:
INPUT: web sized BMP -> desired FILE COMMENTS -> OUTPUT as JPEG at desired Quality and Folder location [JPEG with Comments/no camera Exif]

...to avoid multiple JPEG compressions...
