This image, of the same vintage Flxible Clipper Bus ( https://pbase.com/dlgphoto/image/174562413 ) shown in the previous post, is straight out of the camera except for a little cropping and contrast adjustment. The other image is a processed RAW image. The color differences on the processed image are mostly due to using a channel mixer layer and swapping out the red and blue channels to varying degrees. I have found that this often leads to remarkable color differences, especially when used in conjunction with a color balance layer. The way the white balance is set in the camera also affects the look a lot as well.
