I'm semi-pro photographer currently shooting A-mount both: Film and Digital, currently working as a Software Engineer. Through my history I got experience with most of the systems, wrote several photography-related articles and tutorials (almost none of them in English though, so you won't see me linking to my own materials).

I'm allergic to:

  • crap written by Ken Rockwell
  • "prophesies" of Tom Hogan
  • generalizations based on one or two cameras
  • And people who think that there are only 2 photographic systems for pros: Canon and Nikon (view mostly popularized by mr. Rockwell)

So best way to get a -1 from me is either by linking to texts made by these guys or popularizing bipolar point of view.

What I love:

  • Answers based on experience that goes more deeply than into one or two systems
  • Well-formatted answers that cover all of the matters in a question (even if someone else already suggested an idea you agree with)
  • lists and direct comparisons

So best way to get +1 from me is by reading through whole question and answering every matter touched by it in widest scope possible.

English isn't my native language, so please, forgive me any spelling or grammatical mistakes.

Hope you'll find my answers helpful. And please: remember to mark answers under your questions if you agree with them (+1 doesn't do the job on it's own, though if you want to give +1 and mark an answer - you're even more awesome! ;) ).

comment How to figure out if a DSLR will help my interest in photography?
Yep, we certainly do. As for the other topic, perhaps this would be a good question to ask yourself: How often you have been exhausted while shooting to the point where you couldn't hold DSLR steadily? If you were - then lighter camera would most likely benefit you. If not - then heavier camera would benefit.

comment How to figure out if a DSLR will help my interest in photography?
"it certainly has an impact on muscle vibration when under strain from being handheld vs a lighter device" - quit contrary. When you are tired you'll hold heavier object much more steady than a lighter one. But of course - grip is a huge deciding factor here - shallow grips will force you to hold a device in a way that's very unstable comparing to a proper, deep grips.

comment Should I store my 35mm rolls in the fridge?
B&W films should be cooled too if you store them for a long while - they loose not only their sensitivity but also dynamic range which is one of their major advantages.

comment Websites with RAW conversion contests?
astronomyforum.net/astrophotography-image-processing-forum - they make regular Astrophotography Processing Challenges - but that's very specialized, processing astrophotography differs from regular photos, though feel free to try it out.

comment Postprocessing ColorSpace: Windows System with two graphics cards (Quadro and GTX) one AdobeRGB the other sRGB color space
AFAIK what you are trying to do is not possible, GPU drivers don't allow you to work in two color spaces at the same time, even if there are two different GPUs involved - but I might be wrong. As Philip said - get some professional advice, don't ask random people on the internet about things that involve as large sums of money and specialized knowledge as you need.

comment Why are digital cameras said to suffer more from chromatic aberration than film cameras?
You are wrong. Expectations got nothing to deal with it. Chromatic aberrations ARE more pronounced on digital than film. It can be measured. One of such attempts was made by genotypewriter: secure.flickr.com/photos/genotypewriter/6147351879 - result being quite obvious: Film wins when it comes to CA.

comment Is the maximum CF capacity supported by EOS-1Ds really 8 GB?
It might be related to a cluster size that a camera can read. If 8GB is a limit than it means that maximum cluster size that can be read by build-in card controller is 4KB.

comment When scanning a printed photo, the resulting file is of less quality or resolution than the original?
mattdm - it's perfect theory if you assume that all of the pixels on a print can be automatically mapped to their perfect representation of the pixels on a final image. As I tried to point out - that's not possible. Old rule from the University of Technology that applies to everything: "every measurement includes some uncertainty" - in that case: measurement is scanning, uncertainty is imperfections of scanned image.

comment Why is micro 4/3 autofocus so much faster than DSLR live mode focus?
Depth of field is also a huge factor. With greater depth of field you can allow yourself to focus faster but less accurately. It's a trick most commonly known from compacts - when they got several pre-programmed focus settings and simply jump between them what takes far less time than slowly checking each possible step. But mirrorless cameras use that as well mixed with plenty of guesswork that's possible thanks to shape-recognition software.

comment How to calculate the optimal pinhole size?
As far as I'm aware - differences between these will be rather insignificant in exposure (you'll learn them after few exposures and than just apply your own exposure compensation to balance out exposure exactly as you like it) - it's much more important to get a perfectly round pinhole, than whatever it's 34% bigger or smaller.
