Aliasing and Anti-aliasing Examples

If there’s one thing that digital photography has no shortage of, it’s confusing vocabulary words. Aliasing, which is a common word in the world of digital everything (video games, CGI, photography), is one of those words that everyone has heard, but may not quite understand. And the anti-aliasing feature found on many digital cameras doesn’t do much to explain why you should use it. Not to worry though, for anti-aliasing is no where near as complicated as it may sound.

The Basics About Pixels

Most digital images are made up of square units known as pixels. If you take any of your digital photographs and zoom in a few times, you will notice that the closer you get, the more blocky the image appears. This blocky appearance is the result of the individual pixels becoming more pronounced as the digital image is increased in size. [read]

This week your challenge is to take and share an image on the theme of ‘close to home’.

This bounces off our post earlier today – 5 Photo Ideas for Shooting Close to Home – but you could also interpret it any way that you want and do something a little more abstract on the theme of Home.

Once you’ve taken your “Close to Home” image, upload it to your favourite photo sharing site and either share a link to it below or embed it in the comments using the our new tool to do so. Please note it sometimes takes us a while to approve comments with images as there’s a moderation queue – particularly over the weekend.

If you tag your photo on Flickr, Twitter or other sites with Tagging tag it as #DPSPHOME to help others find it. Linking back to this page might also help others know what you’re doing so that they can share in the fun.

PS: don’t forget to check out some of the great photos shared last week in the PHOTO WALK challenge.

Since I began writing here at DPS, I’ve been shooting out little lists of tips for photographing children. But each little point on those lists has so much potential for further exploration in and of itself and it would be a shame not to delve deeper. Today, I am reflecting back on a post called ‘4 More Tips for Photographing Children‘. Specifically, tip #2 “POV”. The tip was this:

“Try a different point of view. It can add an edge to otherwise same-same photo situations and give your kid shots a whole new life of their own.”

POV is excellent, but what different POVs are there and what statement do they make? How can you practice this tip in your everyday life photographing your kids? [read]

video-feature-digital-cameras.pngOver the last few weeks we’ve been asking readers whether they use the video feature on their digital camera.

While the largest response was ‘My Camera Doesn’t Have Video’ (35%) the break down between the other three responses was interesting. Here is the breakdown of responses from those who DO have the ability to take video from their camera (excluding the 35% that don’t).

I guess all up more people use the video feature on their digital camera than don’t – however there’s a fairly large proportion of those who have video at their finger tips who choose not to use it (some will use a dedicated video camera or perhaps a phone, others perhaps just don’t shoot video).

Black and White photography is among one of the most striking forms. Photos sans color require an enhanced use of lighting, shadows, and subject focus. Black and white photography brings out details usually overlooked in standard color photos. Subject studies is the discipline of concentration on one particular subject. Not quite still-lifes, though they share some similar qualities, subject studies focus on one particular object in view.[via Digital Photography School]

In the territory of the DSLR camera we seem to have inherited a duality that continues, model to model.

On one hand we have cameras with an APS-sized sensor, roughly half the area of the 35mm film frame. These benefit from the use of smaller, cheaper lenses, yet still capture well-accepted images.

In the other hand we have high end DSLRs with full size sensors, like this one, able to use ‘normal’ 35mm lenses, with no enlargement factor involved when comparing the field size. Bigger and more expensive lenses is the price we pay for a full frame sensor.

However, there is much going on behind the scenes as makers of high end medium format digital cameras watch with creeping anxiety as full frame DSLRs lift resolution levels, while offering comparable camera product at much lower prices. Watch out for the battle between Hasselblad and kin versus Canon, Nikon — and Sony.

Sony, in particular, is biffing the market with its attractive full frame pricing, as already seen in the A900 and now with the A850. [read review]
