–Rode the Innerlight in a winding path to the entrance of the Folsom South Canal at Sunrise.
–Grrr…played with photo editors some more, found that ON1 and Affinity both showed vignetting on (I believe an older) RW2 file. ACDSee was fine with it, and (as I already knew) has much smoother sliders than ON1. I upgraded to ACDSee 7 for Mac. Still can’t save jpeg’s at 100% by default, and it seems to lack a ton of stuff ON1 has, but smoothness and “opens anything” count for a lot to me.
