Those first two shots - the backlit hairs - are really cool, Igor. I have not used any stacked DOF software on these shots. The insect shots are hand held with the camera on just a monopod - between my motion and the movement of the bugs, I don't think that I could get enough shots to stack. SOmeone recommended the DOF stacking software for snow flakes last spring, too late to try it, but it's on my project list for next winter...

I like the DOF. Did you do anything special for it? You didn't do focal-HDR, did you? I tried to play with the same combination of lenses a few times, and my results were acceptable but not as good. My biggest struggle was the DOF, even with the aperture closed down. (I posted those attempts to PDML a while ago: http://science.komkon.org/~igor/PHOTOS/Raspberries/IMGP9527.jpg http://science.komkon.org/~igor/PHOTOS/Raspberries/IMGP9503.jpg ) The DOF became incredibly shallow (and the sharpness went down) when I stacked 2.0x with the 1.7x (and still with the same DFA-100/2.8 macro): http://science.komkon.org/~igor/PHOTOS/Raspberries/100-2_0x-1_7x/ Igor On Tue, Jun 14, 2011 at 7:52 AM, Mark Cassino <markcassino at ymail.com> wrote: > This weekend I tested out the D-FA 100mm macro combined with a Kiron > MC-7 2x > teleconverter and also combined with a Pentax 1.7x AF adapter as > alternatives to > a 200mm macro lens.
