    Today I processed a few shots I took in Barcelona last week, most of them at night as usual for me in my business trips. I used noise reduction quite a bit, as I had my Oly 12-40 with me, and shot often at ISO3200.

    I used DXO basic noise reduction and also Prime, I wonder: what is the rule of thumb on when to use Prime rather than the faster option? I don't care about the additional processing time, should I always prefer the Prime algorithm or is there situations where the faster option is better?

    in my case, i would use the faster option from ISO 400-800 and I am processing a lot of photos. Prime benefits from 1600 and up. Sometimes I dont do NR on 100-200 ISO as i like a little bit of grain.

    So far, I haven't noticed any situations where PRIME is the worse choice. The only time I don't use PRIME is when ISO is low, there is no blue sky, and shadows aren't being pushed much.

    I use prime if my ISO gets 3000-6400
