Programmer most of the time and photographer most of the time. In a final analysis, I don't know what I'm more: programmer and photographer. Anyway, I do both for the others. This means that I'm a professional, no? Hummm...

comment Is Mirroring on one card is done through camera or through cards?
Perhaps I wasn't clear: I didn't say that camera copies the image "from main memory into a cache" but FOR the main memory it uses memory chips which are speed comparable with cache chips. Perhaps my use of therm 'buffer' for Main Memory is a little bit misleading...

comment Which focus mode should I use for a portrait shoot?
@dpollitt: For the said camera (Pentax K-30) the AF mode with 1 (one) center point is really 'the best'. See the proof at pentaxforums.com/reviews/pentax-k-30-review/… when you scroll down at 'Truck test' paragraph. You have there the AF modes compared in a 'Hit/Miss' table. Besides that, all nowadays top-of-the-line Canon cameras have the center points - 5 (five) for 5D3 and 1DX and 1 (one) for 6D and 7D2 - much more sensitive than other AF points. They start to work from F/2.8 have a double-cross (Star) pattern, -3 EV sensitivity etc.

comment How do I prevent my camera/lens from focusing on only a subject?
He does NOT have problems with choosing the wrong subject (or 'focus hunting/jumping'). He wants to have "everything" in focus.

comment How to keep shutter speed and aperture when changing modes on Canon 7D?
@l0b0: ...Also, your question was HOW TO KEEP Av/TV and not WHY THESE AREN'T KEPT. IMHO, while I tried to answer you in my comment above, spanning (sub)questions in comments section isn't a good practice.

comment How to keep shutter speed and aperture when changing modes on Canon 7D?
@l0b0: Because, at least historically speaking, these are the two things which affect the photograph in a much greater degree than all other factors while being the most dynamic parameters. This was especially true in the film days when the 'ISO' was "fixed" (you had a roll of film of a certain ISO) and, also, in the modern days when ISO is set to 'Auto' for a wide range of situations, hence the ISO 'disappears' from photog's attention. You can think at all other settings like a more or less stable 'frame' of settings in which you play with Aperture and Time.

Sorry, but I have to mention: Lightroom is the top SLOW dog for managing photos.
