How do you save to be 100k max so that the image is viewable. If I get down to 100k, it really looks like crap and the ones here are better.

Sure you are xgi93. It looks pretty darn good to me for your start.

Biggest issue is to align the frames of course. :)

One of the images appears to have a tiny amount of warp in it (or else my difference aligning wasn't correct!) around the middle of the picture. The damage to the sides on that image give some idea what happened.

I was particularly interested in the Blue channel - in RGB images this typically contains most of the noise - hopefully that should help people identify the channel!

Foghorn002 - can't see your image anywhere.

Hey Dave. Good pickup, but not warp. These are 3 exposures shot simultaneously- back "in the day". Everybody had to hold a perfectly still pose throughout. Guy in middle, kneeling, moved in all 3. Hard position to hold.

Absolutely done that way. Use a Cyan filter and only the Red light wave passes through. Film is panchromatic (not color film yet). Panchromatic simply means that is exposes identically to any light, regardless of wavelength. So the trick is to filter out the unwanted waves, until you have a RGB exposure. 3 Separate at the time.

If you wanted me to build a fake blue channel out of the green why did you include a misleading blue channel? Dumb!

Nothing fake. People are just moving around between the 3 SEPARATE shots the photographer took to compose a color photo. The older man on far right is simply the best. He stood iron-clad , spot-on still. INTERESTING note - you'll find that the piled logs DID NOT MOVE. Good clue...

Sure getting it. A little overpowered by the yellow. Maybe work on reducing that channel or actually doing some SELECTIVE COLOR CORRECTION, taking yellow out of yellow.

Like it! Maybe work on brightening some. Could use some more pop and contrast. A couple of others on here had made that correction successfully. I have to work more on my own to get to where some of them are.
