National Geographic is once again holding their annual Photo Contest , with the deadline for submissions coming up on November 30th.

Collected below are 47 images from the three categories of People, Places and Nature. http://www.boston.com/bigpicture/2010/11/national_geographics_photograp.html

The World's Best Photos of bokeh and leica. Flickr Hive Mind

http://fiveprime.org/hivemind/Tags/bokeh,leica Flickr Hive Mind is a search engine as well as an experiment in the power of Folksonomies . All thumbnail images come directly from Flickr , none are stored on Flickr Hive Mind . These photos are bound by the copyright and license of their owners, the thumbnail links take to you to the photos (as well as their copyright and license details) within Flickr . Because some other search engines (Google, etc.) index parts of Flickr Hive Mind , you may have been led here from one of them. Welcome to Flickr Hive Mind, almost certainly the best search engine for photography on the web. If you are a Flickr user and use Flickr Stats you may have seen people being led to your photos via Flickr Hive Mind (as a Referrer).

It is a somewhat complicated issue. The 40D, like the 30D before it, implements intermediate ISO's by software multiplication after digitization of the raw data. So there aren't really intermediate ISO's, as far as the camera electronics is concerned; instead, the camera overexposes by 1/3 stop at ISO 160-320-640 etc, and underexposes by 1/3 stop at ISO 125-250-500-1000 etc., using the nearest "main" ISO 100-200-400 etc.

http://www.the-digital-picture.com/Canon-Lenses/Field-of-view-crop-factor.aspx With the advent of Digital SLR Camera Bodies , the term Field of View Crop Factor has come into our world. The source of this term is the smaller-than-35mm sensor present in many of Canon and other manufacturers' DSLR sensors. Canon's EF Lenses still focus the image on the same plane as before, but sensors smaller than 35mm sensors do not capture the entire image. Thus, the image is "cropped". The Field of View Crop Factor (FOVCF from here on) refers to the amount of the image that is cropped. Here is a diagram illustrating the size differences between Canon's currently available DSLR sensors (I personally don't expect to see any new sizes introduced by Canon in the near future).
