  1. I explain myself, After 2 days of trials, watching tutos, topics on the forum, I finally managed to have a fonctional 32bits linear workflow in place. I've tried tones of LUTs, OCIO layer and 32bits preview configs but, the better I had was a good viewing and a crap export. Finally I've found a way, perhaps not a good one, but a way. I've read @Frank Jonen talking about a gamma issue on a spécific question so I've tried the transfer fonction trail. It lead me to add an S curve shape on top of my layer stack and this time my LUT worked as expcted and the export too. But why do I need to do something approximative to have all working? Infos: -working with 32bits EXR float (full) linear render -OCIO layer to convert from linear to LOG -LUT layer to apply a creative Log base look -S curve shape on top -ICC or OCIO 32bit preview @troy_s welcome to the discussion
  2. Quite everything is in the title, but to be more contextual, I'm working with 32bits linear .exr (3D renders). To have a proper non destructive workflow I use OCIO layers to convert from linear space to color profil spaces, then I use creative LUT (or do manual adjustments). Exemple: OCIO layer to convert from scene linear to Slog, then a creative Log LUT to have my look, and export to final 8bits format. The problem is at the end of the process, when exporting an image there is an ICC profile apply on top of my stack, so it add an aditionnal transfer curve wich altered my work. I don't talk about how to view my work how it's exported, I know that, but I want my work not to be altered with additionnal transform. I know a cheap way of doing what I want but it's not satisfying. So, is there a way of disabling ICC profile during the export? Or is it planned to add the option in a future release?
  3. Hi there, I've got a problem exporting a CG render. The source is an .EXR 32bits linear, I've applied an OCIO, LUT... everything is correct in affinity (right contrast) but when I export it, it looks like there something wrong with the color profil (not sure). The image looks dull. i've tried different export format, color profil but always the same problem. I'm on windows with Affinity Photo 1.6.4.104
  4. Hi, I stumbled on a JPEG that sometimes shows up too dark in some cases on the web for some reason. Upon investigating what the issue for this was (suspecting an embedded color profile) I also loaded it into Affinity Photo. Upon loading Photo assigns the default color profile (sRGB) to the "unprofiled" image and the image shows up too dark too. Loading the same image into Photoshop results in the proper colours. According to Photoshop the file is in "Linear Color Space". It seems this "Linear Color Space" situation for JPEG files isn't handled by Affinity Photo yet. Also it doesn't seem to be possible to convert the image later into this space unless one converts into 32bit first. It doesn't result in proper colours either, however. Image in question is available here: https://imgur.com/gallery/0DP5M (credit to Reddit user JulianF6 via
  5. I work with images output from a render engine which exports linear colour space files. Usually to save issues further down the line I will convert from linear space to sRGB in photoshop as the first operation and work from there. However in Affinity Photo when I open the linear space render file it is incredibly dark and contrasy - like it doesnt handle the linear space tone mapping. So even if I try and adjust the image files to sRGB its too late and the dark image persists as it is incorrect from opening. Is there an option to correctly open a linear colour space image somewhere im missing? Thanks
  6. Hello. Can the angle of a linear gradient be changed? I have a curved line/stroke which I have applied a gradient to. The angle at which the gradient changes from one colour to another is vertical (0 deg). Can I change this angle to make it lean one way or another, perhaps by degrees? Many Thanks
