Digital Photography Tips - Background Part 2

Last July 3, 2007 I post regarding Background and leave a word to make experiment on it... Do you try it or not if not !!!
Here's another way to get a more diffusely blurred background is to use a lens with a long focal length such as the 70-200mm f/2.8 Lens used for the above Monster Buck picture. It will be much more difficult to blur a background with the 16-35mm f/2.8 Lens of Canon, 17 - 55mm f2.8 of Nikon or 17 - 35mm f2.8-4 lens of Sigma. All focal lengths yield the same depth of field when used at the same aperture setting and subject framing. But, the image compression a telephoto focal length provides magnifies the already blurred background. The result is a background that appears more diffusely blurred.

Shutter Speed 125/1 sec, f/2.8 using 70 - 200mm f/2.8 lens

Using a higher focal length has the additional advantage of including less background in your picture. A higher focal length lens has a smaller angle of view. Pretty simple - less background in your picture leaves less room for distraction. This may be a reason to choose the 180mm f/2.8 Macro Lens over the 100mm/105mm f2.8 Macro Lens. Again, less background in the picture reduces the chance of distractions.
