CMY vs RGB...   Topic List   < Prev Topic  |  Next Topic >
Reply < Prev Message  | 

Ok...this is probably going to be asked dozens of times
in the course of this group, but...

What are the pro's and cons of RGB filters versus CMY filters?

I've looked at AVA's site, and I really like the
sample CMY and LCMY images taken through True Technology filters.

But I saw some unfavorable comments on SBIG's site regarding
CMY.

I'm using AstroArt which supports both RGB,LRGB,CMY,LCMY.

Is this a personal taste issue? Does it depend upon
my intended targets? Would a chiefly planetary imager
pick RBG over CMY? And a nebula imager pick CMY over
RGB? At this point, I'm imaging mostly fainter nebulas
and galaxies so this might make a difference in selection.

Thanks. I would really love to hear from folks who have used
both.

... Wow Ron, cool statement for a president. I agree to color-balance and the color refraction problem in atmosphere. With SNR disadvantage the key would be...

Before this particular subject gets to old, I thought I would post some comments from Al Kelly. "Subsequent studies (since the 1998 S&T article) show that the...

... Hello Kwang, RGB (LRGB) is much easier to colorbalance when it comes to finetuning later because it is more intuitiv IMHO. The CMY filter let pass thru...
