Have been actually putting effort into technique on mandolin lately. Was looking at it this morning after some practicing and thought, hmm - 5x7? Have a new bench/stand for the lathe in the garage that is, as yet, latheless, so I threw a blanket over it and set up a few shots. No lights on, just indirect light from the windows on the garage door. Ended up with the following:
The first one is, to date, my longest exposure: 1:05:00. Shot with the Ross 5" I recently got on eBay. I'm pretty happy with the lens' performance, though I need to actually shoot some more landscape-y things with it. And definitely need to pull it apart and get rid of some of the internal haze. It's WWII era, so uncoated and lower contrast anyway, but it's showing it's filth. The second is with the Sironar-N 210/5.6. Both on Arista.EDU Ultra 100 in HC-110 dil H.
Back to scales...
