Photography Basics: Beginners Guide to Aperture

As part of our Photography Basics series we talked about Exposure already and this time we are going to cover the mystery of aperture. Aperture is probably the least understood setting of everything on your camera. While shutter settings are very easy to understand, to long of a shutter speed and you will get blurring, pretty simple stuff. Same with ISO, too high of ISO and you introduce digital noise. But learning how to use aperture properly can kill brain cells faster than a frat house kegger party.

How to Calculate Depth of Field

A big stumbling block for many new camera users is how to figure out how much depth of field a particular image will have it in given the focal length of the lens, the aperture used and the distance to the subject.

Lensbaby Composer and Optic System 7

Lensbaby Composer and Optic System

In the beginning there was the original Lensbaby lens, a simple bellows system with push-pull focus and left/right and up/down sweet spot selection.

Now, the Lensbaby Composer promises a lens that is easier to use, better control over focusing, and a selection of different optic inserts to give you a variety of different effects.

Based on comments and emails I have received there are still some people that are confused about how the three elements of exposure play together to determine how dark or bright an image is. Today I want you to think of the three elements of exposure as the three points of a triangle each having an equal effect on the final exposure of the image.

Canon EOS 5D Mk II Hands-On Impressions

Oh Canon 5D Mk II, how doest I love thee, let me count the ways. That could pretty much sum up my impressions of the newest camera from the folks at Canon but it probably doesn’t tell you what you really need to know. I certainly don’t have the testing lab that DPReview or Popular Photography has to tell you all the little specs and test results, but as someone who is shooting all the time, I figured I would get my hands on one and see if it really is all that it is hyped up to be.

OnOne Software’s Focal Point 2

OnOne Software’s Focal Point

Focal Point is OneOne Software’s newest Photoshop plug-in that allows you to create images with selective focus and edge vignette effects. Using these techniques you can guide the viewer’s eye to the spot in the image that you want them to look at. Using an easy to use “focus bug” you can control the sweet spot, the amount and kind of blur. These types of effects have only been possible with expensive specialty lenses before. Does Focal Point deliver on the goods? We decided to try it out for ourselves and see what we thought about it.
