I've been doing a study of the Victorian era photographer Julia Margaret Cameron (1815-1879) and have tried to take a few photographs of my daughter Emily in her style.. I am intrigued by Cameron's, at the time unorthodox, approach to "Focus".
Here is a quote reflecting her views "I believe that what my youngest boy, Henry Herschel, who is now himself a very remarkable photographer, told me is quite true - that my first successes in my out of focus pictures were a fluke. That is to say, that when focusing and coming to something which, to my eye, was very beautiful, I stopped there instead of screwing on the lens to the more definite focus which all other photographers insist on."
I took this with one of my old 35mm lenses which I adapted to my 40d. As you can see in the exif data....there's no aperture recorded. The metering was a few steps here and there due to the fact my camera has no fstop factor to work from.
You could buy this lens for $20.00 today. Rikenon 52mm f/2.
