I’m experiencing a rather frustrating behavior which seems to be to be a bug.

I open a file "green_selected.tiff" with the following file path:

/Volumes/mdouma46/Documents/Programming/Check Box/selected/green_selected.tiff

Upon opening the file, and without making any changes to it, I choose the "Save for Web…" command from the File menu. I choose PNG-128 as the setting and save the file back to the original folder. The file path to the new file is then:

/Volumes/mdouma46/Documents/Programming/Check Box/selected/green_selected.png

Immediately upon the finish of the "Save for Web…" menu command, the state of the original document "green_selected.tiff" which is still open in the window changes from "clean" to "dirty". By dirty, I’m referring to the appearance of unsaved changes, by the X of the window’s close button changing to a •.

I fail to see how simply opening a document and saving a copy of it to a different location is in someway modifying modifying the original. I have all color management options turned off, so I am not modifying the document in that way.

Anything I’m missing, or might this be a bug?

I’m using OS X 10.3.x with Photoshop CS.

Same here. Could be a bug.

It doesn’t happen here. I have tried it with CM Policies both "on" and "off".

modifying the original…so I am not modifying the document in that way.

Easy, if the document’s SourceSpace does not equal PS’s WorkingSpace, and we don’t Assign the document’s SourceSpace before we save it, we may in fact be hosing it…

Then again, I may have missed Marks point completely 🙂

You’re not really saving the document if you’re Saving for Web though, right? And it askes you is you want to save changes when you close, too, which is a pain.

Odd that it happens on some machines and not others. Ideas?

Maybe I’ll trash prefs tomorrow and see what happens.

Yes you are! You can choose to Optimize and you can change the name of the file too.

Upon opening a file, if we ignore the file’s source space profile (by breaking PS’s color management, i.e., turning PS’s color management "off") — and the file’s source space does not equal the file’s source space — I think all would agree Photoshop is not displaying the file accurately.

My question is:
Would not Saving the file, in this scenero, "automatically" cause Photoshop to "change either the numbers in the images or the interpretation of those numbers," to use Mr. Frasers words?

In other words, opening and saving the file, in this scenero, has indeed altered it the original color???

In still other words, if my PS Working RGB is Adobe RGB, and I open an untagged sRGB file (and do not Assign the sRGB profile), and immediately save it — have the original "numbers" been altered in the saved file?

Ann,

I don’t think so. You are making a whole new file. Your original document remains unchanged. If you don’t modify it in any way you should be able to close it without Photoshop asking if you want to save. At least that’s how it has worked on all previous versions.

If you don’t modify it in any way

Then the question becomes: What if I do change a pixel and save it — have the original "numbers" been altered in the saved file?

What do you think, Ed?

And save what, the file or the pixel as a new file? If you change a pixel in a file and then save it, yes, you have changed it. No?

But if I take file.psd and use SFW to make file.jpg, file.psd doesn’t go away. For all intents and purposes it is untouched. At least that’s how it’s always been.

Must go to bed. But haven’t we all used SFW countless times? The end product is a completely new file (unless it is a jpeg, say, saved as a jpeg with the same name to overwrite the original. But who would do that?)

See you tomorrow.

Hmm. On second thought (and testing), maybe you’re right. It IS making changes in the original document. But it just seems wrong.
