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 Is the low-light advantage of larger sensors attributable to the sensor itself or to the larger aperture of the lenses?
Folks, I've closed this question because it has fired off a ton of moderation flags as a consequence of the massive quantity of comments (92 total) and edits as a result of being less than clear. Each answer has then led to subsequent, large, comment-based discussions and this is not a discussion forum. This could, however, be a really good chat event that becomes a blog post.

@KartickVaddadi - Answering the question with a link to "go there and read" is not answering the question on this site. It is very likely to get deleted as a consequence.

comment Is the low-light advantage of larger sensors attributable to the sensor itself or to the larger aperture of the lenses?
@KartickVaddadi - The amount of light coming through the lens is independent of the sensor. The amount of light the sensor reads is dependent on the size of the sensor because the smaller sensor reads a smaller portion of the image circle, but the amount of light at any given part of the image circle is the same regardless of the sensor. I have to be honest, at this point the question is becoming a lesson in optics and is getting to the point where it is unanswerable. The sheer volume of commentary is beginning to indicate it is a bad fit for the site and I'm close to closing it again.

If you read the comments, you'll see why they got complicated...

comment How can I sync EXIF information when using a pre-saved PSD template?
I would also recommend learning to use photoshop actions so that you don't put it into this PSD file when editing inside of Photoshop.

@KartickVaddadi - Aperture is only measured one way, it's a ratio of the size of the entrance pupil to the focal length. If you measure the entrance pupil, then you get different apertures. The aperture is what matters for the amount of light being transmitted.

@KartickVaddadi - Every time you try to clarify, the semantic meaning of your question seems to change, I can't read your mind. In any event, you don't measure the physical diameter of the aperture that way for a reason. The point of f/# is to be dimensionless with respect to the lens length so that we can know for the same f/# that the amount of light will be the same, allowing is to select appropriate ISO and shutter speeds. The ISO selection will absolutely impact your noise amount, but if all things are equal, then the sensor quality will determine noise.

@KartickVaddadi - the physical size of the aperture opening will transmit different amounts of light on different focal lengths and will correspondingly mean a different f/# is in play. You keep changing the goalposts on the question I think.

@mattdm - But it's still not going to make the APS-C sensor noisier... That's where he seems to be stuck.

comment What are good settings to use for exposure bracketing?
The camera type isn't really relevant, so I think this is a duplicate of the linked question.

comment Does pixel size make a difference in image quality?
I'm inclined to agree with Matt, the linked question describes how they relate. Does that answer your question in this regards?

comment Is there a DSLR fixed lens camera?
@EsaPaulasto - if it's two prisms, it's not a mirror, but it's splitting hairs at this point. It's a dead concept from what I can see.

@mattdm - Let's see how it goes then... :)

Have you reached out to either company at all? What was their feedback?

comment What gear do I need to trigger off camera Nikon speedlights from Sony NEX6?
@MichaelClark - If I recall, Sony has moved away from the old Minolta hot shoe and gone to the standard format. The NEX6 shoe looks normal to me.

+1 now that I've actually seen the source image...

Hmm... works if I click directly (rather than opening in a new tab).

@Frank - Well, that's partly because none of us can access the image you linked to...

Missed that... Might work, but not sure if the virtualized hardware will support it.

The big change in Mountain Lion was that 32 bit apps that required kernel extensions were DOA and it wouldn't surprise me if these were needed given the purpose. It's not really analogous to Windows in this respect.
