Chromatic Aberration (CA) typically shows up on a photograph as blue or purple near an edge that is high in contrast. It is caused by the lens having a refracting index that is different for varying wavelengths of light. What this means is that the speed of the light traveling through the lens does not stay constant across the whole image. Changes in speed of light through the lens causes Read More ...

A common way to get sharper images is to stop the lens down. It is generally excepted that the range of f/8 to f/11 is the sharpest. This has been a loose rule that I have followed while taking my photographs. But how can we be sure? Where in the f/8 to f/11 is the sharpest? How much difference does it make? These are some questions that I’ve attempted to Read More ...

This is a controversial topic that comes up often on photography forums. While most will agree that RAW is the way to go, there are still those that hang on to the notion that JPEG is better. While shooting in JPEG has it’s useful purposes, I believe RAW is the best way to get the most out of your photos. My goal in this article is to explain the advantages Read More ...

If you own a Canon XTi (400d), you probably have noticed the lack of a good white balance setting for indoor pictures under artificial light. Set the camera to automatic white balance or tungsten and the picture is too yellowish. Use a gray card (or sheet of paper) to set the white balance, and the picture is unnaturally white. None of the other white balance presets are any help either. Read More ...

F-stops are relative measurements of light. When I say relative, I mean, that there must be some context for a comparison. Saying f/4 for example, means nothing without mentioning what we are referring to. Most of the time we are talking about a particular lens. “I shot this picture at f/4″ implies f/4 on the lens used to take the picture. Ok, so what is an f-stop relative too? It Read More ...

Bokeh, from the Japanese word for “Blur”, refers to the image quality of the area of a photograph that is out of focus. Often, the best way to make a subject stand out, is to make the background blurred. To do this, we want to make the depth of field as shallow as possible while still keeping the main subject in focus. The depth of field is directly related to Read More ...

Camera ISO Settings Film has an ISO level associated with it and when it is loaded into the camera, the cameras ISO setting must be set to match. Digital cameras have an ISO setting as well, but it is just a setting somewhere in the cameras menu system. What exactly do these ISO levels do? The ISO level that you use to shoot your photos is a standard that tells Read More ...

To get the sharpest images possible, it is a good idea to stop down your lens to around f/8 to f/11. For some lenses this number might be as low as f/5. This range is where most lenses perform their best. Of course, you won’t get fast shutter speeds, but if you have a still subject and are using a tripod, stopping down the lens can make a big difference Read More ...
