Re: CS5. <sAVE as> unusual things.??

If your srgb image views differently in the browser depending on if you used save or save-for-web, then i believe you embedded the profile in one image, and not the other. If you embed it in both images they should be identical.

Also, the above post by john is good and worth a read. Make note of the 4 points at the end; Always use srgb for web, and embed the profile (we are talking important photos, not layout/design elements).

Note that save for web should be better when trying to get the best quality vs. File size in Photoshop.

nebulaoperator:
I just ran a quick test for you, and I can confirm that there is no difference in colour if I use "save as" or "save for web" (but file size can be considerably smaller when using save for web). My image was in sRGB.

However, "save as" defaults to embedding the profile, while "save for web" defaulted to not embedding the profile. Make sure you choose the same setting when comparing. Embedding the profile (or not) can affect how the image is displayed by the browser.

* In IE9 all my images were displayed the same no matter if the sRGB profile were embedded or not. It did not match Photoshop.
* In FF6 untagged images displayed like in IE9, but tagged images displayed like in Photoshop.

Hi John,
Thank you for quiet in depth comment.
How to do that image is tagged with ICC ?Maybe here I still do mistakes.
Other than that I always make sure image is in sRGB color space.
Cheers

Re: CS5. <sAVE as> unusual things.??

Chain,

When <save as> image and profile is already sRGB does that mean file is emended?
When <save for web> there is an option <embed color profile> I ticked that one and left one <convert to sRGB> unticked (presumed it is all ready embedded sRGB profile)
is it correct? I will run that test again though

Re: CS5. <sAVE as> unusual things.??

When using save as, in the save as dialogue (when choosing file name/format) there is a checkbox at the bottom with the name of the image profile. If that one is ticked the profile will be embedded.

When using save for web, it is the "embed profile" option.

"convert to srgb" should not make a difference since your image is already srgb.

Re: CS5. <sAVE as> unusual things.??

I will go ahead and toss in the images from the two dialogs (picture is worth a thousand words). I used the words ICC because that is often the three character file tag appended to each file (International Color Consortium). Sometimes the files have an ICM tag. That file is the same as what we refer to as the Color Profile in the dialogs below.

Image at bottom of dialog for PSD, TIFF, or JPG using File > Save As

Partial Image or right side of dialog for File > Save for Web and Devices
Screen shot 2011-09-12 at 10.58.28 AM.png

Hope the cut and pastes make it more clear.

Good point Nebula
I do operate on a Mac and sometimes forget that some of the dialogs/panels are different depending on OS.

I did note that in your File > Save to Web and Devices dialog you do not have "Convert to sRGB" selected. With the settings you show, the Color Profile will be attached to the image yet the it will be the Profile in which you have been editing (which may not be sRGB). Since not all browsers are Color Profile aware (and often default to an assumption that all images are sRGB), your images would probably not look right with browsers/OS combinations that do not color manage. FYI

His image was already in sRGB so for the sake of this example it should not matter. However I agree that it is best to leave it on by default just in case.
