Care to tell the brand and the model of it? I'm just curious as I don't 
know any 16-bit/channel video card (I'm not caliming that there aren't 
any..).

In context with the rest of this threads in this group, I can totally
understand why you might think I'm being sarcastic. Because I saw no posts
in the thread yet, I thought it would have a different context but I was
wrong. Lemme explain: I think I understand why you are so concerned about
the color being exact because of your style of art. Most of us are
techno-types so we are thinking in terms of technical merit. Where your art
isn't highly technical, it is very /artistic/ and your use of color appears
to be what you are focussing on. So, when I saw the subtle blue on the
right, I thought, "A person who isn't concerned about the color wouldn't
bother to be that subtle with the blue." I also didn't read the entire other
thread because I'm too busy which is why I kept out of argument -- I still
don't know enough about what is going on.

...I do know, however, it took me all of 2 minutes to install Irfanview and
get the plug-ins...

I think people are failing to appreciate the uniqueness of your art and
judging based solely on technical merit. If I were in your shoes, I would be
just as frustrated. I'm not trying to cause trouble (although sometimes I
am, but in this case no) so please, guys, don't take my words defensively;
I'm seeking to understand IMBJR and the more I /try/ to understand IMBJR,
the more I change my perspective on his work. You gotta admit -- it is very
unique work and, with our help, he will gain in technical skill and make
even more interesting works in the future.

> Wittering on like that makes you look like an ignorant fool.

It's pretty well established I'm an ignorant fool -- in fact, thank you for
your kind words, because there are a few lurking around who would use
stronger words than that! :-)

Sure -- it is an NVIDIA GeForce3 Ti 200. Since it's off-the-shelf (and
probably a year old now) I'm guessing it probably isn't more than 8 bits per
channel, but I don't know much about video cards so I can't speak with any
confidence about anything on this. All I know is that it was damned
expensive new :-)

Yeah, I think every consumer videocard are 8bit/channel cards, including 
yours - despite the price ;) And most likely most of the pro cards are 
also. This might change as now PhotoShop, for example, is beginning to 
support 16-bit tools.

Tell me about it: I upgraded my computer last autumn and bought the 
fastest (back then) videocard - Radeon 9800Pro. It was some 400+ 
euros/dollars. I paid about the same amount for my computer :) But oh, 
how smooth are the games now :)

True, it is worth the price just to load up your favorite game and drool for
a few hours :-)
We've had overheating problems (we, meaning my buddies -- they are the
hardware guys, I'm the software guy, so my machine is custom built -- by
somebody else :-) )

IIRC, BDW left of his own accord.  AFAIK there has been only one person 
banned from this server, and it was for much worse abuse.  I could be 
wrong.

IBMJR has toned down a good bit recently after being directed to  
provisions of the AUP.  BDW didn't seem to care.

I understand IMBJR in his desire to promote an improved image format, but
compatibility is very important here.
As long as the common news readers and webbrowsers don't support an image
format it's better to stick with tradition.
Top quality images should be in png anyways (or 100% quality jpeg maybe) and
for showing a new render to others the standard jpeg format seems to be
sufficient. I haven't heard anything complain!

Funny enough, the only time I buy a faster CPU is when the game I 
really, really want to play comes out that I can't play with a slower 
CPU.  And I remember when the Amiga came out, and people said "What, 
that? Why'd you buy that? That's just a game machine."
