B_Cannings Posted June 5, 2021 Share Posted June 5, 2021 Developers - I downloaded and installed the beta update (1.9.4.243) today, as I was encountering the same issue with Canon RAW (.CR3 format) images rendering in color when opened singly, but rendering only in greyscale when viewed as part of light frame astrophotography stack. Trying the same experiment using the 1.9.4.243 beta update resulted in the same issue; the .CR3 image opened outside of the astrophotography stack workflow color-rendered correctly, but the images opened within the astro stack workflow rendered in B&W (see attached). Apologies for the pixelated nature; these were shot with a 12 mm lens, at only 1 minute of exposure (40 total images in the stack), so the images have to be magnified a bit to see the color (or lack thereof). I might suspect that memory issues are to blame (my iMac is a vintage 2013, with only 8 MB of RAM); does the astrophotography stack workflow access system memory in a way that would cause the images to color-render incorrectly? It seems like others have had this greyscale vs. color for astro-stacking issue solved after installing the new beta version, but it appears to persist for me (and maybe some others, as well?). Thanks in advance. Link to comment Share on other sites More sharing options...

B_Cannings Posted June 9, 2021 Author Share Posted June 9, 2021 Sure thing, Chris - here are two examples, both of which open in color in the raw persona, but in B/W when viewed in the astro stack. Thanks for the reply. -Joe IMG_0525.CR3 IMG_0526.CR3 Link to comment Share on other sites More sharing options...
Staff Chris B Posted June 11, 2021 Staff Share Posted June 11, 2021 Hey Joe, I've tried this moring and I cannot seem to find any settings that retain the colour - I'm not entirely sure what's happening here. Even changing the Bayer pattern doesn't solve it. I will log this with the developers.

B_Cannings Posted June 11, 2021 Author Share Posted June 11, 2021 Chris - my thanks to you and the development team for looking into this. And thank you for verifying that (a) I'm not color blind, and (b) I'm not going crazy! Chris B 1 Link to comment Share on other sites More sharing options...
