Subject: Re: Colors are making me mad!
Thanks for the tips. I thought the exposures had to be similar in order to get accurate
color. Obviously that isn't working for me :)
I will do that the next time around. I am very familiar with Photoshop and had played with
the channels quite a bit. But with either red blown out or blue barely existent, there was
just no saving anything. In fact, when pushed (or pulled) that far it does some whacky
things (especially to the saturation).
Now I know better, I can shoot better. I'll give it another try. Looks clear tonight, I wish I
could go out. Maybe I'll try tomorrow.
Wish me luck (I'll earn the skill later)

I am trying to shoot with this B&W camera, and I must be doing something wrong.
First off, I am having a lot of difficulty trying to get an exposure that will work with all
three
colors. If I expose the Red properly, the blue is non-existant. If I expose so the blue
shows
ANYTHING, the Red is blown way over-exposed.
OK, so I shot a few Mars shots and I stack them up. These are straight from Astro IIDC
and all
three shots have the same camera settings. Put the red in the Red channel, Blue in the
blue
and green in the green. What do I get? A very mucky red color that doesn't show any real
white or come close to the colors I get with color camera.
This time I did shoot through an IR filter for all exposures.
Am I missing something there?
Please help me before I send this camera back for a color version :)
