It would help to know your workflow for saving the images. Why do you need to open a high-res TIFF simply to save to another folder?
While the PPI has changed, does the vertical x horizontal pixel count remain consistent?
Photoshop didn't change the resolution on your files unless you changed it via Image Size, cropping, etc.
How are you seeing the images reduced in resolution? Are you viewing them in another application (one that may not read metadata correctly)?
Hi Marian, I scan in my painting as a TIFF and crop and clean dust and whatnot in PS and save in a folder called "BASE", then I add a few adjustment layers, sprucing it up to optimize contrast and whatnot, then I "save as" a TIFF (with the adjustments) into another folder called "FIXED." When I go into Bridge, all of the TIFFs I have saved into FIXED show 72 ppi instead of the original BASE ppis which range anywhere from 600 - 1200 ppi. Do you think this is because in my PS Preferences, new documents are set to open at 72 ppi ? I wish I could specify in Preferences to ask me what PPI I wanted to open (or save) each document in because each one is different.
I am only using Bridge to view the info on these files, because Get Info does not give me ppi information.
There is no such preference because Photoshop doesn't do anything like that. Photoshop does not automatically change the resolution of your documents. You have to do that yourself.
And no, the new document preferences have nothing to do with opening existing documents or saving them.
Somewhere, you either saved to a file format that doesn't support resolution, or changed the resolution yourself.
Thanks Chris, Apparently User Error was the problem here, as you indicated . I went back and re-did everything, making completely sure I saved correctly each time and everything seems to be working as I believed it should have yesterday. Thanks for clarifying that PS doesn't do random stuff you don't ask it to do.
