Hello I would like to bring in a tiff that has transparency built in as an alpha channel. Publisher automatically reads this transparency. However I dont want it to show the transparency. Is there a way to do this as a switch in publisher rather than converting the image to a jpeg for example? Thanks

Thanks once again for your useful help Kirk. Ive done a simple screen grab to compare to the native photoshop handling and it looks bang on to my eyes to be honest. Yes bummer there is no option to blanket apply the OCIO to the whole document on opening for sure. Good tip on the macro though. I will need to investigate further on the most optimum way of handling this for 15 or so layers at once as it will be tiring doing it for each one. The grouping option could work but I often need to mix layer orders up so the process might break down. On a separate note I've tried to import my photoshop brush collection that I use all the time but to be honest they dont play well with affinity which is a big stumbling block. Im sure I could recreate similar ones in affinity but its another time consuming process and some compromises might have to be made. I like the way you can create a full colour stamp brush in affinity though.

Thanks so much Kirk this has been a big help. I found the utility-linear-sRGB OCIO file applied as an adjustment layer has brought me back to what I see in both the Render frame buffer and photoshop and I've saved it as a preset for future use. I have also done a jpeg export test an it fairs pretty well, not a massive shift in the greens which is good. This might mean I can stay in linear space whilst editing which as you say is better but I have had experiences in the past where its tripped me up on export with colour and contrast shifts compared to keeping everything non linear sRGB. So the next Q is - can I make that adjustment layer permanent for the whole stack of render passes that I have below this adjustment layer without flattening the stack? I can see issues cropping up with a mixing of converted and non converted layers getting mixed up above and below the adjustment layer which could be avoided if I could make the adjustment layer permanent instead of live. Thanks again, you have been a big help.

Is there a support email address I can contact serif directly on about this? Or is this the best way to get their attention? Maybe I'll repost in the bugs section as this has quickly dropped off on to page 2 never to be seen again. Currently Affinity is unusable for professional 3D if there is no way around this which is a shame as I really like the tool set.

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
