I need someone with an old version (pre-CS, but the older the better) to run a test for me. Steps 1-4 can be with any version, but step 5 needs the old version.

1. Open any image
2. Go to "Save As" and choose TIF as the save format
3. When the compression dialog appears, choose JPG (any compression amount)
4. Finish saving
5. Reopen the just-saved TIF in your old version of Photoshop
6. Report back here whether it worked or not (with your Photoshop version and OS)

On saving there's a message that warns some editors will not be able to open the new file, I need to verify that at least Photoshop can, even if it's an old version.

Thanks in advance.

Photoshop 7.0; Windows ME
Saved photo as a TIFF with JPEG compression of 5 - "test.tif"
Warning message: "JPEG compression is not supported in older TIFF readers."

Tried to open in Photoshop 3; Windows 3.1
Message: "Could not open test.tif because the TIFF file uses an unsupported color space."

I then tried to open the file in Photo-Paint version 5.0, Paint Shop Pro and Pagemaker 6; OS Windows 3.1. Would not open in any of these either, although regular TIFFs open with no problem.

Hope this helps.

It helps a lot, thanks. I'm not concerned over any app but Photoshop. Just out of curiosity, would PS7 open it?

Does anyone have PS6 or PS5 to test?

Hi Doug,

Used PS7 and Windows XP.

As has already been said, when saving got prompt "JPEG compression is not supported in older TIFF readers, Use JPEG compression? Y/N".

However I had no problem opening the TIFF file afterwards in PS7.

I used the same TIFF file I had created earlier in Photoshop 7 and re-opened it in Photoshop 7; Windows ME. No problems.

Discovered I still have Photoshop 5.5 installed on this machine.
Tried to open the TIFF file in Photoshop 5.5; Windows ME. Opened just fine. If it opens in 5.5 then it would probably open in 6.0 also.

Excellent, thanks!
