Software architect and developer, currently Senior Manager, Software Engineering at a financial institution 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 Why do pro photographers use huge lenses to take portrait shots?
Interesting read... visualsciencelab.blogspot.com/2011/09/… I now, officially, wonder if the "what the pros use" is more of a marketing thing than a reality...

comment What is one “stop”?
@ysap - Hmm... I see what you mean. Yeah, I'll update.

comment What is “pixel density”?
@Ysap has given the technical answer, but hardware specifications are seldom a real measurement of camera quality. If it were, there would be little point in having reviews...

comment Why are larger sensors better at low light?
@Matt Grum - For sure, but the vast majority of people will never, ever, notice or likely care. They're content, just as they were when they shot 110 film in a Kodak brick and printed on 4x6. Nothing wrong with that, but image quality isn't really a selling point to them.

comment Why are larger sensors better at low light?
@Itai - That's because many people won't actually print them. They either post online, use them as computer backgrounds, or display them in a digital frame. Photo printing seems to be getting less and less common, sadly.

comment Are mirror-less cameras good enough to buy instead of a DSLR for home/amateur use?
Yeah, that's what I've been hearing. The EVF is besting the pentamirror, but not quite up to the pentaprism for now. Of course, the operative word(s) are "for now." ANd then there will just be us dinosaurs holding onto our OVF in the same way many held onto film... ;)

Where do you stand on EVF versus OVF? You didn't really talk to the viewfinder but not a few of us see the electronic option as a drawback at this time (future there may change).

comment Are mirror-less cameras good enough to buy instead of a DSLR for home/amateur use?
@mattdm - Yeah, I can buy that. It's only fairly recent that there's been a move away from the 4/3rds in the mirrorless or, at least, non-reflex so I think many of us tend to think that the EVIL cameras are all in that realm.

I agree with @dpollitt, it's basically the same question. I have to say, though, if the T3i is a scare away, then you're probably out of the dSLR market because it's as consumer friendly as it gets really.

comment Could you recommend an under-$30 tripod for a DSLR?
+1 - I absolutely agree, a $30 tripod would be an utter waste of money.

comment How to postprocess photos with lots of blue haze?
@ysap - Indeed, curves is the more powerful option and also one that, fairly often, can confuse the newcomer. Depends on how much tweaking he wants to do. :)

comment How to postprocess photos with lots of blue haze?
@ysap - Mine is channel by channel which may account for the subtle difference, but yes, it's just a different tool for the same action and result. Some may find it a little easier, that's all.

comment What's the standard photo dimension on mobile devices?
I think this isn't really a photography question, it's more of a hardware question marginally related to photography. In any case, you could probably figure it out by looking at the specifications for the major phones through Wikipedia.

comment How do I eliminate green-screen bounce?
Have a look at this: photo.stackexchange.com/questions/9418/… which is my very similar problem with chroma key and portraits. It may fix it for you.

comment How do I select all pixels that match an exact color value in Adobe Photoshop?
@Unsigned Code Labs - There's a Stack site in Beta that I think is better suited to this: graphicdesign.stackexchange.com

I don't think this is a photography question...

comment Can I publish (online) a photo I took of someone else's house?
@MikeW - I think if the permissions defining you allowing to be there include no photography, then you could stumble on trespassing as a result of violating those conditions. Jurisdictions may vary, however, in this regard.

comment Is there a photo print provider I can use to offer a “Buy a print” feature on my own website?
@eisberg - I haven't used them, but you might want to just ask them about that. I would be surprised if they didn't.

comment What is the difference between in-lens image stabilizing and sensor-based image stabilizing?
Pentax K-5 with their new GPS module are able to keep the sensor attuned to earth rotation for up to 5 minutes because it's free floating and can be adjusted in three dimensions. They call it the astrotracer feature and it works very well.

comment How can I affect color of a water droplet shot?
ElendilTheTall has covered the basics I think. The bounce from the backdrop is how I did these: grumpyjohns.com/2009/psychedelic_water_art
