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.
