Beautiful photos, AlanF!I've now done a test of PRIME vs DeepPRIME on a real image. It's a Migrant Hawker Dragonfly taken on the R5 with the 100-400mm II, 2xTC, f/11, 1/160s iso 1000. I did this a week or two ago using Adobe LR, followed by Topaz Sharpen-Stabilize and Topaz Denoise to get the best image then. Now, I did better straight off with DxO PL4, and very quickly. The two full images are at the bottom, reduced by the site to fit. At the top, is a comparison of the eyes at 100% crop. For PRIME alone, the very top (or on the left if your screen is narrow), you can just make out the individual lenses. Below (or on the right), they are less distinct with DeepPRIME. It fits in with my chart testing last night, DeepPRIME does remove the tiniest of detail, but still damn good.

The 1st (Prime) definitely looks better than the 2nd (DeepPrime). But it may be because they are using higher values for sharpening/contrast etc. Whatever the reason, to me Prime looks much better when pixel peeping.
Thanks for the post!
