  1. First post here. I've been working on a composite of images captured during totality & getting some banding artifacts in PS when forced to use 16 bit mode rather than 32 bit for sharpening steps. I'd like to make sure Affinity Photos has the adjustments I need in 32 bit mode. The complete workflow for PS is describe in this tutorial by Russell Brown: PS Spin Blur Eclipse Processing From Photos tutorials, I see there are spin-blur filters, Apply Image: Equations panel & an Equations panel. So maybe everything I node is there but done differently in Photos. The key step I'm unsure about is in one of the equations panels. In PS, a duplicate image is spin blurred & the alpha channel of that image is subtracted from the original alpha w/ an off-set of 128 in the Calculations panel to give a low contrast mid-gray frequency mask. That mask is then Overlayed onto the original. I'd like to confirm that all this can be done in Photos in 32 bit mode? Here is a version of my PS work from 77 images w/ artifacts & a mask. The frequency mask reveals the finer corona detail. Thanks!
