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

Hey everyone, thanks to the great OCIO support and the performance, I´m using affinty photo more and more to process my still linear exr renderings out of octane for cinema 4D. Unfortunately I'm having an issue with alpha masking of groups with this workflow. These are the steps I take: 1. I'm rendering a half float linear exr and use the "object layer color" for alpha masking [because it's faster to render inside of octane]. 2. I take the exr into affinty [1.8.0.585] 3. Use OCIO to convert the Image to sRGB 4. Below that, I adjust my exposure if necessary 5. On Top, I have a LUT to convert the Image to sRGB ICC 5. I right-click my black and white (but still RGB) object layer color and rasterize to mask 6. I drag a drop the mask on my grouped beauty [regular beauty and denoised beauty] 7. As a result, the mask is very pixelated and unusable. Masking a group seems to cause the problems. Without the group everything works with and without OCIO. The same mask and grouping works fine in Photoshop. The Photoshop files looks different because its without OCIO but adjusted exposure, otherwise it would be way too bright. Thanks in advance!

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?

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

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

Hi, I need a precise gradient in 32-bit mode, to go from left to right. (I use it as a texture in a game - the values control some math functions over time.) The "Noise" value is set to 0 (or so I guess, because there is no numerical input). Yet still there is a visible dither. I use version 1.5.0.35. Win 7 64-bit, NVidia GTX 760, newest drivers.
