When you’re shooting in cold weather conditions, there are a number of considerations that you need to remember when shooting, and one of them is that a cold camera will tend to fog up once you move back into a warm environment.

This isn’t just annoying, but that moisture build-up on the camera could get inside the optics or the electronics and cause issues. Maybe not at first, but down the line you could hit a snag with corrosion or mold. Here’s how you prevent it. » MORE

For digital SLR owners, the megapixel war is over. Six megapixel is the magic number for most consumers who want “big prints” (ie. 8×10) and ten megapixel is the magic number for publication. Anything more is gravy.

Much more, and you could be running into alternate problems. When you cram more pixels onto a sensor of the same size, you’re making the pixels smaller, and smaller pixels have less capacity to handle light. » MORE

Today we’re talking about color spaces. There isn’t a good general understanding of color spaces and their limits, and because of that - there is a lot of confusion and bickering about what to use. These are shark infested waters we’re wading into. If we’re not back in 30 minutes, call the authorities.

While there are plenty of color spaces available out there, the two that are most often available on digital SLR’s are Adobe and sRGB. While you can convert these to any other space in post processing, there’s typically not much benefit, so the question is - sRGB versus RGB (or Adobe RGB)… what’s better? What are they? » MORE

You remember Radiopopper - the RF piggyback units that are designed to extend your range beyond that you can get with existing systems inside the Nikon or Canon flashes. There were a few different units, set to be released in a staggered schedule - but the news of them has been received with suspicion amongst many pro shooters who already use similar systems. Many claim they are vaporware - hardware that will never be approved for use in North America and thus, never see the light of day.

Radiopopper might beg to differ - and has several new images posted that show off the design of the little unit.

Engadget reported earlier this week that Canon had an “eye-based biometric photo watermarking system” patent pending. That is, the camera will have a sensor which will read the user’s iris and will record a registration code embedded in the image at the moment of power-off. » MORE

The “magic lens” is Adobe’s first crack at manufacturing camera hardware. The company is well known and respected as a software developer, but this could signal a shift towards gear, or it could end up being a one-off experiment for Adobe.

The lens (video of it after the jump) is actually 19 lenses piled together and aimed at slightly different angles. The result is an image that lets you control the perspective (a little bit) and the depth of field in post processing. » MORE

The pre-PMA announcements are flying fast and furious now, as Sony announces two more digital SLR’s for their line up.

The new A300 and A350 cameras will fall between the existing A700 and the A200, and offer some new features. » MORE

There’s a great show in Canada called “How It’s Made”, which airs on the Discovery Channel. They get invited onto the factory floor for all sorts of manufactured items. This video follows the process of putting together a lens on the JML Optical assembly line. As you would likely guess, the process will vary between manufacturers, but this might give you a little insight as to why those camera lenses are so expensive. » MORE
