  1. In short, Affinity Photo develops my RGB monochromatic images as RED when using the Auto-Colors tool, which breaks my processing macro for handling images SOOC. I've attached a sample example JPG from my Fuji X-S1, and the file as batched with equivalent (with exception of Auto-color which does not exist in PhotoPlus x8) SOOC workflows. I don't know an answer on how to address the case of what should be monochromatic images having (stupidly?) auto-color run against them, but I feel like this should be more robust. The alternative is I have to make another batch processing macro and run that only against monochromatic images, which sort of defeats the purpose of batching to begin with if I have to sift through files and take them out one by one.

  2. Hi guys, I do this in Photoshop to normalize the R, G, and B curves for the negative film (yes, I scan 35mm film) : - Create a new 'Curves' layer. - Click the little arrow at the top right of the Curves properties window, and select "Auto Options...". - Click "Enhance Per Channel Contrast" and "Snap Neutral Midtones", and set the shadow and highlight clipping to "0.01". - Click "Save as Defaults" and then "ok" out of the Auto Options window, and now click the "Auto" button. What I've just done is to normalize the R, G, and B curves for the negative film. A little background: essentially, negative film has characteristic curves for R, G, and B light. But these are not coincident with each other. If you were to take a photograph of a neutral grey patch and look at the histogram of the negative, you'd find that the blue channel would have the highest intensity, followed by green, and then red. What you need is, for a neutral grey patch, to ensure that R = G = B (that, indeed, is the RGB *definition* of "grey"). So in this curves layer, you're correcting for this R, G, B curve offset by forcing the histogram for each colour to use the entire histogram range (that is, you are enhancing the per channel contrast...as per the Auto Option box you checked above). I need to do the same using the Affinity Photo that I have just bought it :) Any way to do this ? Thanks
