Hi, first of all affinity photo is powerfully image editing software at price which is equal to few months of Adobe subscriptions. However in regards to raw development affinity isn't there yet, at least for me. The problem is histogram in raw isn't usable because it is different during and after development. This bug is well described in few topics on affinity forum, but it is still not solved. The second problem for mi is shadow lifting which is completely unusable because it gives some kind of muddy over saturated look without any details (in my case at least). Anyway download free trial and see for your self if it works for you.
