Guten Tag Roger,
This is a very difficult question for me. While there must be some reason I have all these various cameras and lenses, or even why I have a refrigerator holding more film than food, I cannot seem to find technical reasons behind these choices. At least, there is not a technical aspect in my images that someone could point out as being a certain camera, lens, or film . . . except maybe my Polaroid manipulations. If I leave out the Polaroid manipulations, I am left with a wide variety of approaches.
When I first started reading this thread, I thought about colour being the technical aspect I valued the most. However, that does not explain why I shoot B/W, which I find to be more illustrative. Funny thing is that I also shoot B/W when I need images to work up a painting, since I don't want the colour of what I photographed to influence my choice of paint colours that I will use on the painting.
At one point I was doing a ton of selective focus or ultra short DoF shots, which I still do quite often. However, I also find some concepts work nicely with a very large DoF. Then there are view camera shots that are done with a skewed plain of focus. I once told some people at an exhibit opening that I use film and cameras the way they were not intended . . . might be why I do Polaroid manipulations.
I have some very good lenses, and very good cameras. Many were chosen based upon their ergonomics, since what I wanted was gear that became an extension of my creative vision, and that did not intrude upon nor distract that creative vision. On smaller cameras, fast lenses make for very clear viewfinders on SLRs. Focus is technically important to me only in that I need to be able to control it. An extremely short shutter lag seems somewhat important, though it would be nearly impossible to pick that out in my images. The old folder cameras I use are well maintained or even functionally restored, but what I like is the lack of precision . . . simplicity.
Finally, I just dropped off a 4x5 transparency at the lab to be printed for an upcoming group exhibit. It is a selective focus image with a shifted plain of focus, shot on Fuji Astia 100F. I managed to swing, tilt and shift the lens far enough to cause one corner to be a bit dark, though it is in an area of deep blue sky. The lab commented that they could touch up the image and get rid of the dark corner, but I thought that it created a more interesting image. Life is not perfect, so a little imperfection might be something viewers of that image find interesting. I guess that today with so many polished and post processed images showing up as prints, something selectively focused with a dark corner lacks that all too common striving for technical perfection.
Ciao!
