Affinity Photo is an intuitive and affordable image processing tool. With astrophotography data, it is common to work from the linear stage, meaning that your data’s histogram has not yet been adjusted and stretched. There are a couple of occasions when working with Affinity Photo where the data may be represented in a non-linear format when in fact the data is still linear. James Ritson from Affinity will show you these occasions (while not detrimental to your processing) and how you can configure Affinity Photo to always show you non-linear data when it is non-linear.
