Color shift on Google Drive
« on: May 26, 2023, 01:01:11 pm »

Hello All.
Not sure where this belongs so I'll start her.
Working towards a book. Uploading 90 fotos onto Google  Drive for submitting to a publisher. The first try went well. The colors  were good. When I uploaded a revised folder of the fotos the colors shifted a lot. When I reloaded the folder the results were a little better, but still not satisfactory.
The fotos are between 5 and 15 MBs, in Tiff, flattened, and in ProPhoto.
Any help will be greatly appreciated.
Richard

Was the embedded profile (ProPhoto) stripped?

Andrew,
Thank you for responding.
Not sure if it was stripped. Don't actually know what "stripped" means.
I did flatten the file by going into Layers.

Get a document off Google Drive (FWIW, I don't use it, no idea how it deals with documents).
Open back up in Photoshop: there should be an embedded ICC profile stating it is in ProPhoto RGB. AND look OK.

Got a file off G.D. Put it into PS. Under Edit chose Color Settings. Says it is in ProPhoto RGB.

And it looks OK right?
So where's the issue: "fotos the colors shifted a lot" where?
Photoshop is color managed; anything that doesn't match isn't.

Colors shifted on some of the fotos, but not on others. What's curious to me is that the first upload looked good. But I decided a few of the files were a little off. So I copied the original files to  a new folder, tweaked a few, uploaded the folder and saw most of the fotos were way off. I can't say I say a pattern, but the blues in the sky, in many of the files, were a bit purplish.

Uploading 90 fotos onto Google  Drive for submitting to a publisher. The first try went well. The colors  were good. When I uploaded a revised folder of the fotos the colors shifted a lot.

Assuming you used a web browser to upload your photos to Google Drive, the destination files are bit-for-bit identical to the source files.  Google Drive doesn't alter anything: it's simply another storage medium.

If you uploaded the files with some other client application software that uses the Google API  (i.e., a program other than a web browser), I suppose it's remotely possible the client could have done something squirrily during the upload process — but that strikes me as extremely unlikely.

More likely, some change in your local environment, or in your publisher's.
