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 bright should a flash be?
Augustin-Jean Fresnel may want to take issue with your second paragraph... Mind you, that is more about shaping and directing the light, but the perception is brighter. :)

comment How bright should a flash be?
Wow, sorry, but I think this question is way too broad. The way I read it, it's the start point for a rather large book on the topic of lighting... What are you trying to do? The amount, and nature, of lighting varies from scene to subject to purpose. There's no magic answer here.

comment Are photo releases necessary when using event photos in my portfolio?
+1 - I agree, I've never heard of this being an issue.

comment Is it risky or difficult to wet clean an image sensor?
Sensor shake for this is handy, but not perfect. With my K-5s, I will do the menu based option on lens change, otherwise I just have it on startup. It's not 100%, but it really cuts down the overall volume of dust.

comment What are common beginner mistakes in photography?
@mattdm - Part of the premise of the site is that general questions have an answer that can be accepted. This is not such a question, I think, there will be a lot of answers that are equally valid. Such a question then can be closed as subjective, a vote for this already exists, or it can be more generally informative as a wiki page. I think wiki makes sense here, it can be useful and, as a wiki, is more open to editing than it would be otherwise and that, hopefully, leads to more useful outcomes.

comment What are common beginner mistakes in photography?
Bingo! I agree, 100%. It can get far worse than that too... It gets to the point where some think it's the gear that makes the image.

Assuming you shoot the big 2, not all of us do.

comment What are common beginner mistakes in photography?
I have to say, I actually preferred the first shot. It had a lot more depth and contrast to it, the second looked washed out and plain. Sorry, you may need a better example... :)

comment How can I get the same image with the same 50mm lens on both FF and APS-C?
@Itai - Crop the FF stills to the same field of view as the APS-C and I think you'll find that perspective is the same.

comment How can I get the same image with the same 50mm lens on both FF and APS-C?
@Itai - faulty intuition this time, I'm afraid. Call it crop factor or focal length multiplier, it means that 33mm x 1.5 gives you an approximate 50mm lens on APS-C.

@Jukka - Point taken.

This looks to me like it's more appropriate for community wiki, there's no "right" answer here to accept.

comment What is the best way to hang or mount photos for a showing?
+1 - Love the quote too.

comment Are there dSLR cameras which can take movies without a rolling shutter artifact?
CMOS or CCD? An even quicker search would rapidly assure me that just about every dSLR in the 35mm format is CMOS based... :)

@Jay - Fair, done!

comment Why is Nextgen / wordpress is reducing the quality of my photographs?
I think Alix has the root cause. The GD2 library is the one used in Wordpress/NexGen and your display in the site context is using resized images.

comment Are Konica and Minolta lenses interchangeable?
Some interesting detail here: buhla.de/Foto/Konica/eHexanonHaupt.html (it's in English)

comment Can lens focus speed affect continuous shooting speed?
Is it a menu setting to control focus lock and shutter release? It is on Pentax, not so sure with Canon.

comment Does Canon have a no lemon policy on EF lenses?
+1 - On a side note, I think you can get by, on the bodies, with a 7D and a 5D for the "pro" designation. That's actually pretty cheap to some degree, the Pentax pro body is the 645D at $10,000. Though it would really appear, at least in Canada, that it is sufficient to say that you're pro to have Pentax accept it. :)

comment Why don't most cameras support PNG format?
Given that TIFF is the basis for the various raw formats, I'm not sure that you can assert your last paragraph.
