PS Seems to Open ART Converted Crop Tiffs Incorrectly

Hi Alberto, thanks for ART, I find myself using it more and more - and really like its logic.

One issue I have had recently has to do with a NEF converted and cropped in ART, then saved as a 16-bit TIFF to be opened in PS: PSE2020 and CS5 try to open such a file via ACR, and they think it’s much smaller than it actually is. Below you can see how the files look in ACR and File Explorer, RCD and AMAZE are the two files converted with ART that show the issue, the other two were converted with other converters and PS opens them fine.

I am no expert but either I did not crop them or export them properly, or the TIFF format they were saved in is not compatible with those two versions of PS. I tried to find a way to open an issue on your site but could not figure out how to do it, so here it is.

Thanks for any help and keep up the great work!

Hi,
My guess this is a metadata problem. Are you exporting with “copy unchanged” perhaps? There’s a blacklist of bad tags that shouldn’t be exported, but maybe it’s not exhaustive… Can you try exporting with “strip metadata” enabled?

Yes, by clicking strip all metadata it works. ‘Unchanged’ and ‘Apply’ with the defaults don’t.

Hi, can you share a tiff that works? I’d like to pinpoint the culprit…

Here is the NEF, I release it for any use.

Here are the three TIFFs

https://drive.google.com/file/d/11_8L74T927NKjLfGBriaNG4io9uvZhkk/view?usp=sharing, https://drive.google.com/file/d/17k6IJZLf2eIPQAve2g-4WLcr05r6GqVC/view?usp=sharing, https://drive.google.com/file/d/1jPThcvciNoReLowjtLs9l1Bp3L1C8gid/view?usp=sharing

RCD doesn’t open (copy Unchanged)
Apply doesn’t open (Apply Modifications)
Strip opens (Strip All Metadata)

sorry, I was unclear… I meant a TIFF with metadata, but produced by another tool (e.g. ACR or Capture NX). There’s probably some wrong tag that confuses PS, but since I don’t have the latter, I was thinking of isolating it by looking at what is missing in other working TIFFs…

Ah ok, this one is from PSE 2020. Incidentally, RT at default (Copy unchanged) exports it fine.

I think it might be due to missing “XResolution”/“YResolution” tags. Can you try adding the info with exiftool and see if that helps? (i.e. exiftool -XResolution=300 -YResolution=300 filename.tif)

Tried it but I am afraid it doesn’t work, it still thinks the image size is 14x9 while instead it is 336x226. I also tried 600 for the resolution, to no avail.

It has been a very long time. I recall there being multiple resolution related tags (e.g. resolution unit) that could muck up things.

Hi @JackH,
could you try the two attached tiffs and let me know if they work? Thanks!
test_1_withresolution.tif (2.0 MB)
test_1_withresolution_artist_copyright.tif (2.0 MB)

And here’s another one if you don’t mind…
test_1_withresolution_artist_copyright_nousercomment.tif (2.0 MB)

Success Alberto! All three TIFs opened fine in PS CS5 and PSE2020.
