1. Re: Basic Color Profiles Question (using PNG's)
Mylenium Oct 11, 2012 8:20 AM (in response to jyeager11)And where are monitor profiles in your equation? I'm afraid you're looking in all the wrong places...

Noel Carboni Oct 11, 2012 8:34 AM (in response to jyeager11)Actually, Internet Explorer HALF color-manages. It only reads the document color profile; it ignores the monitor color profile and assumes your monitor implements sRGB IEC61966-2.1. This will make IE right 100% of the time if your monitor is actually sRGB. It will be wrong 100% of the time otherwise.
Based on your description, I'd say in your case you likely have a wide gamut monitor, not sRGB.
There are settings in Firefox you might want to explore that will make it do reasonable things with untagged images and web page elements.

What a nicely worded explanation!

jyeager11 Oct 11, 2012 8:49 AM (in response to Noel Carboni)Understood, but say we're observing on a single monitor (for the sake of argument, let's say a Dell P2210). Is there anything I can do to a PNG as far as color profiles are concerned to make images appear the same on IE and FF?
And will this problem be moot later on when IE finally does use color profiles the way everyone else does?

conroy Oct 11, 2012 10:52 AM (in response to jyeager11)Photoshop does not embed profile in PNG for some reason. There's a SuperPNG plug-in which does, though.

Noel Carboni Oct 11, 2012 5:06 PM (in response to conroy)Actually, Photoshop DOES embed a profile in a PNG if you use Save As, not Save for Web. Go figure.
[ admin - it was an oversight, that some bored engineer undoubtedly has addressed by now ]
Microsoft shows no sign of interest in advancing the state of the art of computing, and I mean that in the most serious, somber way. There's no evidence that Internet Explorer will ever take into account a monitor profile.
And no, there's no way to make Firefox and IE match on anything but an sRGB monitor. Sorry. This is one reason why I have set up an sRGB reference system myself.

conroy Oct 11, 2012 4:29 PM (in response to Noel Carboni)Something strange is happening because I rechecked before posting, and the Save As PNG dialogue definitely had a grayed-out "embed profile" option and definitely no profile was embedded.
Now if the doc is 16-bit, the embed option is available and the profile is embedded.
And if the doc is 8-bit, the embed option is grayed out yet the profile is embedded.
What the f*** ?!?
