I have encountered some (for me) confusing behavior. I have been working with both aperature and photoshop cs4. When I take a file from aperture to cs4, aperture creates a file with the extension.tiff. when I then save the file after working on it in photoshop it saves with the extension .tif. that is to say, Aperture uses 2 ‘f’s and photoshop uses 1 ‘f’ which results in two files. Is this related to option choice in the Tiff save panel or something anomalous with aperture.
Thanks for any suggestions.

A good question for the Apple Aperture forum.

..tif (the three letter extension) is the correct extension

(too bad Apple is too stooopid to realize all file extensions should be a dot + 3 letter extension for cross=platform compatibility, ooooh, wait, maybe they do that on purpose).

It is stupid. Shoot-yourself-in-the-foot stupid — particularly if you can’t (even) choose ".tif" as an option.

All systems recognize .TIFF or .TIF (just as they do .HTM or .HTML and .INX or .INDD). There is no ‘dot + 3’ rule for cross-platform compatibility. Jeff may want to get out a bit. 🙂

While it is odd that Adobe is not following a standard with their own software, it can be represented either way.

which results in two files

That is a different matter and has no relation to how many letters are used to define TIF/TIFF.

I have played with this a little more and this is what I found. The file created by aperture has the tiff extension. If photoshop is set up to open all tiff files using camera raw, then when editing is complete and the file is saved it will be saved using the save as dialog even if save is selected, and the tiff file saves with a single f by default. The second f can be added in the save dialog box in which case it asks if you want to save the file that already exists. Save over the original tiff file and the edits will be visible in aperture.
On the other hand if camera raw only opens tiff files with adjustments, the the save command saves directly in which case the two f extension is maintained.
Apparently use of camera raw causes the save as dialog box to come up the first time the file is saved. Thus one can either add the second f in the dialog or forgo the use of camera raw for tiff files being brought in from aperture.
