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 Pentax K-5: Is it worth using the Premium JPEG quality setting?
I agree with Matt, but I usually skip the JPEG option and shoot only DNG with my K-5s since that gives me the best options. Since you can always convert in camera later, I don't see any reason to shoot only JPEG.

comment What would be examples of Principle of Alternation, other than chiaroscuro?
Alternation isn't just light and dark, it can be lines and curves, warm and cool, etc.

comment What are the advantages and disadvantages of using auto ISO on a DSLR?
@Freed they explain it in the manual, but the control of this does depend on the camera. For Pentax, it's call "Program Line" and is coupled with other settings to determine the behaviour. You can always try some sequences out with your camera to get a feel for the behaviour.

comment What are the advantages and disadvantages of using auto ISO on a DSLR?
@Freed - Not so, auto ISO in other modes does not mean unpredictable. The camera should allow you specify the creative parameter to favour adjustment. For example, in aperture priority, you can favour the shutter speed so ISO will rise before that or you can favour ISO and shutter speed will decrease. These aren't random at all.

comment Is it possible to get precise framing with an unstabilized lens with a long focal length?
@mattdm - Me too, normally I just use seagulls for practice, but I liked this one.

comment Do rented lenses usually come with cheap filters attached?
I think I'm more amazed that you were able to rent a Pentax lens!

comment What camera has the highest number of frames per second?
Are you asking about video frame rate or the frame rate of still cameras?

comment Upgrade Nikon D80
Pentax as well. The K-5 has a dedicated AF button, so I disable the half press on the shutter. Mind you, I've never noticed any real lag on the Pentax cameras, but this is still a better model IMHO.

comment How can I calculate vertical field of view from horizontal field of view?
@mattdm - 4mm diagonal is about 49 degrees, so maybe, but that's a fairly large margin of error for a pretty precise formula. Either way, that's the formula for field of view, regardless of horizontal or vertical. :)

comment How can I calculate vertical field of view from horizontal field of view?
That does imply, presuming the camera makes use of most of the real estate, that the numbers I ultimately gave are pretty close to the size you described... Geeze, you guys really need to get off this archaic measuring system, especially if you can't be consistent about it! ;)

comment How can I calculate vertical field of view from horizontal field of view?
@mattdm - That 3.2mm on the horizontal wouldn't yield a 47 degree angle of view with a 4.4mm focal length though, that math doesn't change.
