I just noticed this in Photoshop. I don't know if its just started happening or if I'm just noticing it now but I'm opening a bunch of giant jpg's in photoshop, and after I shrink them down and add a little to them, when I do a save for web, the image gets significantly darker when its in the save for web window. Even with 2 up or 4 up, the original is mach darker. You can drag the window over and compare it to the real original document and see it too. Its really bad. Is there just a setting set wrong somewhere, or is this a known bug? I'm on PS 7.0.1 in OS X.

Your color management is on. Go to color settings and change them to the correct settings. If your are developing for the web, you should really leave it on web graphics.

I've never made any changes too it, but I've noticed PS 7 still likes to do its own thing, from time to time. Ill check it out

OK the color settings window doesn't look quite like I thought it would. What settings do I set to make it not change my colors when I save for web? Changing the RGB space doesn't seem to have any effect, it still darkens it when it saves to web.

Try turning color management off. I was having the same problem a few weeks ago. Basically, I had the same color settings as my g/f's PC but for some reason, the Mac settings were darker and way off from the PC. I turned color management off and now everything seems to be in order.

Where? I don't see any options to simply turn it off.

Photoshop-->Color Settings. The first pop-up will be for color settings.

My options are "Custom" and "other" with other greyed out

In the actual save for web panel there are options for uncompensated color, standard windows col, standard Mac col, etc etc.

Could be set to Windows standard...always a tad darker. Drop down menu. Arrow just to the left of the 'save' button.

Not a bug, just a feature. Adobe changed the color management around version 5 or 6, I forget now. Everyone was spazzing out then, thinking it was a bug, but it's not.

If you're not doing CMYK work, ignore those options, and try setting your RGB working space to Monitor RGB, which will use your calibrated profile for your monitor (which you should calibrate if you haven't).

I have my monitor calibrated to PC gamma to begin with (using the "expert options" in the Monitor/Color control panel), so that it looks consistant in Photoshop and when I'm checking work in the browser. You may, I'm afraid, need to go back and adjust your photoshop work to look correct in this new working space. You could try an adjustment layer of Levels or similar.

The only issue I have surrounding this now, is that PNGs that are exported for use in Flash seem to always notch their gamma up a few half-points for no apparent reason. I assume this is something to do with the file format of PNG. If anyone knows about this, please share.
