After processing a number of 16 bit images in Affinity Photo, I exported them as 8 bit tifs. I have the Embed ICC profile and Embed metadata boxes ticked. When I viewed the 8 bit images in BreezeBrowser Pro they were very slow to display. I've contacted BreezeBrowser support and they have suggested that the issue is probably that Affinity Photo does not produce an EXIF thumbnail and this is why the display is so slow. Is this the case or is there an option somewhere that I need to switch on?
