I hate gamma

[eub]

My kitten pictures are the way I want them in Photoshop, but in IE on Dee's machine they show up disgustingly dark. I can't figure out who to blame. When I'm working with computers, I like to know who to blame.

Are there relevant hardware differences (e.g. Mac vs. PC)?

When I was the person in charge of the NetBill web site, our graphic designer used a Mac and most of the rest of us used Suns (with a couple PCs thrown into the mix). Her graphics always looked too dark on every non-Mac machine we had. I'm glad we had one Mac so we were aware of the discrepancy, but it was a bloody nuisance to get stuff that worked reasonably on all of those platforms.

This is even between Photoshop and IE on the same PC.

If it were between different machines I would be happy, because I would know to blame the designers of the JPEG file format. (Macs and PCs assume different gammas, 1.8 and 2.4 IIRC, and the image contains no indication of which it's encoded with. Orangutans, morons, radiators.)

Argh! Well that certainly sucks. What does other software have to say on the matter? (For example, does Netscape agree with Photoshop, IE, or neither?)

JPEG format: leaving something that important unspecified sounds pretty stupid to me. Sigh.

Looks to be Photoshop's fault. On a gamma test image, it shows 1.8, while IE and a couple of image viewers show 2.3 or so; I wonder if Photoshop is helpfully trying to enforce Mac gamma. No way to adjust it, that I can see. I guess I have to calculate the remapping curve to correct this and apply it to each image just before sending it out the door.

This is "Photoshop LE", to be accurate. Well, Deanna was lusting after the real thing anyway. But if it doesn't fix this I'm going to hurl it into the sun.
