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]

I want to look at some ways to break out of the mold and take striking portraits by breaking (or at least bending) the rules and adding a little randomness into your portrait photography. I’ll share ten of these tips today and a further ten tomorrow (update: you can see the 2nd part here).
1. Alter Your Perspective

Most portraits are taken with the camera at (or around) the eye level of the subject. While this is good common sense – completely changing the angle that you shoot from can give your portrait a real WOW factor. [read]

3 Penguins Photography

When it comes to DSLR photography sometimes things can get a little complicated, this is especially true when it comes to making the first purchase after your kit lens. Do you choose a zoom lens, a wide angle lens, a prime lens or even a fixed aperture lens? Well don’t worry yourself to much because this article is here to help you.

Zoom Vs Prime

A zoom lens will allow the photographer to zoom which isn’t to surprising. The advantage of a zoom lens is the ability to zoom in and out on your subject to create the perfect composition. Zoom lenses are favored by most photographers because of this function, however zoom lenses usually have higher f-stops than prime lenses, and this means that they usually leave less light into a photo which will affect the shutter speed being used.

Over on my post 6 Tips for Setting Your Photography Prices, there has been some discussion about whether a photographer should ever sell original, unedited files. There’s also some questioning whether photographers should sell any digital files at all, edited or not. But then, that’s a common dialogue always going on amongst photographers.

I just thought I’d pick up on this idea that we would ever sell raw, unedited images. One reader commented that since she’s a photographer, her wedding photog sold her the complete package of raw files for her own editing pleasure. Honestly, as a photographer myself, I can understand why she would want more creative control over her wedding photos. But as with any facet of the photography biz, if you compare photographer practices to any other service, they don’t always make sense. [read]

You’ve probably heard of High Dynamic Range (HDR) Photography, it’s made quite an entrance into the world of digital photography.

If you haven’t, the HDR process is accomplished by taking multiple exposures of a high contrast scene (usually a landscape or cityscape), at different levels of brightness, and then combining the best light from each exposure into one image.

The end result is a stunning image that very closely resembles how the human eye views a scene. This process of digital manipulation has caused a bit of controversy and debate in the world of photography, especially with images that are “over-cooked.” One thing is for sure though, HDR is here to stay. When done right, this unique and in depth processing technique can produce beautiful works of art that mimic the way we view and remember a landscape or scene. [read]

While I have been dabbling in photography for a couple of decades, I never have ventured underwater with the craft except with the use of a small 110 film camera when I was a child and recently with a small Canon P&S. That all changed earlier this month when I was lent an Aquatech CO-7 Sport Housing for my Canon 7D from BorrowLenses.com for a trip to the Riviera Maya region of Mexico.

While this review will be specific to the Canon camera housing I was lent, Aquatech’s housing all share a commonality in making the most vital camera functions accessible. Also, the build quality and operation of the housing (opening, closing, fitting) are nearly identical across their product line. [read]

Okay, the 1.1 section had what was admittedly a pretty rudimentary exercise. Which maybe explains why many of you didn’t uh, actually do it.

This stuff is the equivalent of “wax on, wax off” in the beginning of Karate Kid, and you really want to explore these things in an environment where you are not also trying to make a real photo at the same time.

The point of this exercise is not so much to stretch yourself, but to just go and do it. Walk before you run. Start building an easy comfort zone and then stretch it.

For those who want to check out the results, you can see the tagged and posted results here. And it is good to see that most of you are navigating the Flickr posting and tagging issues just fine. [read]
