Excellent. Many thanks. Not sure if i talk to you or AI, if it is the latter than it works. rgds, YK

Carl That is annoying not to be able to batch job PNG files in develop persona. Anyway I need to correct for vignetting of the lens and that is not covered in your suggestions. Many thanks again. Young Kon

Carl, Thanks for your quick reply. Much appreciated. I tried your suggestions and re-looked at James Ritson video, but I failed again. I use a Mac and and Mac equivalent to .RAW files is .PNG. Assistant is on Serif Labs. 1) When I drag a .png file or open a .png file, Affinity does not go to develop persona, but remains in photo persona. So i decided to open develop persona in the toolbar and continued with your suggestions, but then 2) I cannot change the output file to linked or embedded. rgds, Young Kon

As far as I can see i cannot make the same adjustments on multiple fotos in develop persona, such a lens corrections on all my photos

Thanks for you interest. I use a Canon 7D mark2, a 400 mm lens at f5.6 and Mac OS. I am new in Astrophotgraphy, tried to photograph the andromeda galaxy, but i now understand that the magenta color is probably due to little photons hitting my camera sensor. rgds, Young Kon

Could somebody explain why all my raw astro photos have a magenta color in Photo 2. Better can somebody tell me how to get rid off this color before i start editing.
