Tried a little experiment today that I think I'm going to use tomorrow for a local fly in. Put .9 (three stop) ND in the drop in filter holder of both my 300mm and 500mm lenses.
Did this for three reasons:
1) Better Subject Isolation (at prop shutter speeds, DOF is way, way too deep)
2) Cleaner Backgrounds (another aspect of ultra deep DOF)
3) Less Visible Dust (the bain of being at f/11 and smaller)
If you'd care to see some test shots I did this afternoon, go here:
...and then check out the next six in that gallery. The titles contain the settings and other info.
Just as an example, this was at f/4.5 instead of the usual f/8 and smaller...
Interesting. I noticed at Road Atlanta during a early, early AM practice I was at f/22 for some stuff. I thought I had left the ISO cranked from the night before. I look down and I'm at 100, not a sweet spot.
