Exif Editor

[arturox]

G'day folks...
I have some old PSP file I'm working on ATM and find as was per usual for PSP in the old days, all the Exif data has been stripped.

I have (paper) diary notes of when they were actually taken, so my question is...
Anyone know of an EXIF editing app that will work with PaintShop Pro files, so I can at the least put back the Date they were taken.

Thanks
Arturox

Nb: I have been searching online but those I've tried won't touch the PSP filetypes.

I have an Alt route as a last resort, but don't want to go there unless no direct PSP route is available...

No, I can't think of any that do as it's never come up for me since the new ones deal with it quite well. PSP prefers to edit IPTC data not EXIF. Though entertainingly if they knew how to grab the data, all of the EXIF editors could easily edit PSP's exif data as it follows normal conventions.

PSPImage format stores TIFF Rev 6.0 style EXIF data in a block in the file. And most EXIF editors can edit this kind of data, they just don't read the PSPImage format to grab this far more common format. The newer versions of PSPImage also save Adobe style XML EXIF data.

Given time and effort, thanks to the PSP File Format PDF, it would be possible to create an EXIF editor. Though, I wonder how hard it is to add new formats to existing editors? EXIFTool reads PSPImage exif data but doesn't write it.

I've been doing a lot of experimenting with various ideas...

One was, make a Tiff file out of the old PSP file, the Tiff will process through the EXIF editor okay... Add a bit of required EXIF info and save.
BTW. My app of choice is "Exif Pilot".

Bob's me uncle... loading the Tiff back in to PSP 2018 yes the EXIF info is intact.

Save out as a PSP file, then load back into PSP. Naaa! Exif data mostly stripped.

So it appears, the only two file types to maintain EXIF data are .tiff and .jpg.

Moot point I guess... PNG files will store a limited amount of XIF and XMP data but unfortunately PSP doesn't see or read it.
And FWIW. Neither it seems does the Win 10 Filer...

Imagine a list of naughty words follows...

PNG format doesn't directly support exif data. If exif pilot supports adding it to png files it's through an extension or application specific tag that most readers won't support.

What version of PSP are you using? And what EXIF tags are you setting? When I open a raw format and save it to PSPimage format it retains all of the EXIF information that PSP supports. I verify this by using the Image Information command in PSP.

I think I noted it in my original post... PSP 2018.
I'm only interested in the date when the photo was originally taken. All other tags are irrelevant in this exercise...

Sorry don't know what "... the Image Information command in PSP." is?

I have a Blue "I" tool bar button that gives me image info.

All the old files are going to be renamed variously, so I've decided to take a much simpler route to assauge this EXIF aggravation by renaming the files thus:

2004-04-04-Funeral01.png or .psp or whatever file type it is...

Nb: I did a rough calculation yesterday... All the time I've spent writing here and a lot of time testing Exif editors, I could have easily changed all the files names as above noted and had time to spare. :-/

Aside... Interesting to note...
Even PSP 2018 does a bit of Exif data stripping.

An example being:
Out of camera Jpeg contains 'Make' and 'Model' of camera... Saved out as a PSP file those two data field are empty.

There are only two file types that reliably retain Exif data, Jpeg and Tiff.

I really must stop playing and get back to my task...

All Exif Select items are ticked.
