All those images seemed to be processed correctly (stipulating that "correctly" in the context of "true color" images of Mars is a pretty controversial topic). Right filters in the right places. The sundial is pretty close match to the images taken on Earth in the Mars Yard.

It was hard to figure out directly how you processed the images, and I had to go look up the raw images to find out. A suggestion I make to everybody doing color combinations is to include basic processing info in the output filename.

For example, when I combine L4, L5, and L6, the filename contains "L4_L5_L6". When I also adjust saturation and brightness, I append that info: "L4_L5_L6_sat-45_lum-50" translates into a saturation reduction of 45% and a brightness (luminance) reduction of 50%. Contrast reduction would be "_con-nn", gamma correction would be "_gamnnn" (where nnn" is a three digit number like "090" for 0.95 or "115" for 1.15), and so on. As an alternative, when I'm going to a lot of trouble to prepare an image for public display, like when I grandstand here, I put that info in the image title block.

I know it's a pain to do all that, but I think it's important both on general principles, and because the question of "true color" in Mars images is so controversial that I feel a need to carefully document how I handle the images.

You're on the right track, keep going!

PS: Speaking of the naming of things: Up until recently one of the most active posters on the Zone used the handle "SDAITech1" (uh, I mean, his handle was and probably still is "SDAITech1", but he isn't posting these days). Every time I see your handle I first think he's returned, then an instant later my brain unscrambles the letters. Would you like to use your first name here to lessen the confusion?
