This is one of my favourite lenses. It has a superb balance of proprties and is, IMHO, much better than the 85mm f2.

The title suggests you were experimenting with a CPL filter, which is only any good to control polarised light if there is any. I'm not sure there would be any here, but it would have enabled a longer exposure time by cutting down the overall amount of light.

You could also try running together the "relection" with the main subject, eliminating the land, and see what that gives you.

This system is simple and works without any effort whatsoever.

It's all to do with magnification. At the other extreme a Minox is quite vulnerable to shake, despite what we see being achieved in all those spy movies.

The logic of this is sound, but larger formats are often used on a tripod anyway. I always found I could use a Rollefilex fairly safely at 1/8sec. but the Spotmatic was always at least 1/30sec with the standard lens.

The trouble with our eyes, or looking at it another way the advantage, is that we adapt. A sort of biological AWB.

A faster synch speed makes for faster camera operation and also reduces the influence of any ambient light on the exposure. That's why photographers like faster synch speeds.

Not good then. I'd stick to IR triggers wherever possible.
