Just an FYI, one of the NPN member discounts is now: Helicon Focus - 20% off
I’ve been playing with helicon a lot the past couple weeks and am very impressed, especially with the dng workflow, it’s way cool to end up with a raw file.
I also spent a lot of time with Zerene a couple of years back and it did the best job on some moving wildflowers, but I think I like the way Helicon works better now, so I’ll be making the switch and using the discount myself.
