Thanks for the explanation. (I don’t understand all of it, but someone else will.)

I have to say:

I am hesitant because those features are missing. I tried about 15 minutes on how to copy stuff into channels but gave up after this.
It is very crucial for me to have this work, same as full TGA compatability.
 
The chance that I will purchase it is high. But not now.

Thanks Red! 

I know it's slightly offtopic, but if any of the Affinity peeps read this: listen to Warren.
 
Good to see you here, I learned a ton from your tutorials!

I'm sure there's a proper term for this but I love the feature in Photoshop where I can, say, be using the brush tool.  I hold down Z, change my zoom level, let go of Z and it pops back to the brush tool. That is a fantastically fluid workflow and I think would make a smart addition to Affinity.

This is a very basic request that should in theory be very easy to implement, but I would like the ability to export a completely uncompressed tiff file from Affinity Photo.  I am aware that the data compression used in tiff files in Photo mathematically lossless, however, there are scenarios in which even this lossless reduction in redundancy can be undesirable, in cpu processing demands of doing this compression for when the file is intermediary or storage constraints are neglidgeable, preserving backwards compatibility with very old programs, or in my specific case, using images as a source for wavetable synthesis, or general image data sonification effects.  
Yes, there are workarounds, like file converter utilities, but giving user control on whether or not lossless tiff compression is used would be so much simpler, something I've encountered in pretty much all raw / raster image editors I've used.

Going to +1 this request.  Channel control and being able to save to TGA are important to making inroads into the games industry as a tool ...

I first encountered this problem when I tried to migrate to an earlier version of Capture One (I don't know if Phase One have fixed this now).  At that time I had to convert thousands of TIFs from LZW to Uncompressed just to test out Capture One.  Another problem with LZW is that it isn't fully supported for 16bit files. I.E., LZW should only be used on 8bit files.  Lastly, LZW doesn't really offer any advantage, as uncompressed files are often smaller (unbelievable, but true).
