  1. One feature missing from Affinity Photo is the ability to handle One-bit, or black-and-white images. I do a fair amount of scanning black-and-white documents, making small edits (typically cleaning up) and then saving them. I typically use Vuescan which will scan my documents and save them as 1-bit black-and-white tiff documents. I can open these in PS CS5 or in Paintshop Pro, and they open as 1-bit documents. If I open these tiffs in AP, they open as 8-bit RGB! Not even as Greyscale. I would expect that the histogram should show just black and white pixels, such as in this histogram (from Curves): However, what it shows is a histogram like this (also from Curves): Affinity has clearly found a range of pixels (in a 1-bit image) with intermediate values. I can apply a threshold in the Curves Adjustment at 127, which does indeed give me the histogram as seen in my first image. Can anyone explain this phenomenon? John
