Software architect and developer, currently Director of Architecture at a Canadian software company in Toronto. I use a variety of technologies but at work it's generally C++, HTML, ASP (JScript), Flex, and SVG. For personal stuff, I tend to use PHP, C#, perl, and everything I use at work. :)

I've been designing and developing for well over a decade in the enterprise software market, first with IP billing, now with ticketing (no, not TicketMaster). I'm a classic case of a jack-of-all-trades, but my intuition is good and I pick up programming languages like a sponge picks up water.

I'm a moderator on Photography.SE and I'm an avid amateur photographer and especially enjoy nature and macro photography. I've also started getting into more studio oriented stuff, acquiring some lighting, background stands, and other gadgets for that purpose. My current weapon of choice is the Nikon D800. Check out my website for some of my photography DIY projects, some of which have been featured on the well-known DIY Photography site.

I'm now on 500px and you can see my portfolio that is in dire need of growth...

I'm also a moderator pro-tem on Pets.SE because I have a keen love and interest in animals. Over the years, I've had as companions dogs, cats, rabbits, hamsters, guinea pigs, fish, turtles, and budgies. As a result, I've learned a lot about caring and enjoying, sometimes the hard and sad way.

comment How can I get a 'touristy' photo of myself when travelling alone?
@jrista - It was not getting out that got me into playing around with other stuff. I was all nature at first too. @ysap - Try macro, water drop, or smoke photography. Lots of fun.

@jrista - Thanks, I was playing with film noir at the time, a genre I'd really like to do some more in. :)

comment Is there software which can identify the lighting in an existing photo?
Ah, the best software in the world is probably the human brain. Algorithms could be developed for this that could make reasonable approximations based on highlights and shadows, but why do it? The human brain is likely to jump to the answer faster under todays technology than a computer will.

@Itai - I tend to agree, but that's not what he asked... :)

comment Is high ISO useful for photography?
Both are my photos taken with a Pentax K-5... I'd say high ISO is handy. :)

comment What's the difference between PEF and DNG RAW formats?
I haven't seen it yet for Pentax, having gone K10 to K20 to K5, but sure, it's not an assurance since DNG allows for proprietary data.

comment What's the difference between PEF and DNG RAW formats?
Not sure I quite agree with you on the need for the converter updates for DNG. I bought the K-5 before the ACR update was out and had zero conversion issues with it when shooting DNG. I also was able to use Raw Therapee, which was much older, without issues as well. That's part of the big argument for using DNG.

comment Why are tripods forbidden in some public spaces and how to deal with it?
Same answer as me, but earlier, so I guess I should vote up. ;)

comment What is the point of film canisters?
@Evan and @jextee - Even better as salt and pepper holders for camping. :)

comment How can I test a new lens to make sure it is operating correctly?
and @whuber - Notice I didn't say how to use it, just that I said to use it. Just my take, real world means more to me, so my interest is in how it performs with real images and that's using it to me. It may be just an hour, but getting the lens into the situations you want to use it for is the real test that matters.

comment How can I test a new lens to make sure it is operating correctly?
I so want to say "use it" as an answer, but I don't want to sound like a jerk doing so. However, I think it's legit. In other words, don't expend effort on determining if it is "operating correctly" as it is meaningles, expend effort on determining if you like what you get from it.

comment What “start up” telephoto lenses do you recommend for Canon for wildlife photography?
I'm having a harder time with the "not sufficient for wildlife" statement. I have a friend shooting wildlife using this very lens on a Canon 7D, so what's not sufficient about it? In other words, are you sure that the lens is really your limiting factor?

comment Why might my camera show spots in video mode?
Yep, looks like dust to me too.

comment What is special about lenses with f-number < 1?
@jrista - Would the correction not be in the rear elements then?
