Here’s a helpful 22-page guide by National Geographic that explains many of the basic concepts of photography, from lens types to composition. It’s a free excerpt taken from the 400-page book “National Geographic Ultimate Field Guide to Photography“, and is a great read for anyone just starting out.
In response to the “widespread, continuing pattern of law enforcement officers ordering people to stop taking photographs or video in public places”, the American Civil Liberties Union has published a helpful article that clearly details what your rights are as a photographer in the United States.

If you use Photoshop, you’re probably experienced with the uber-useful — and oft-abused — Clone Stamp tool, but what about the Clone Source panel that’s been around since CS 4? This brief but informative tutorial by Photoshop guru Brian Wood is a great primer for that panel, and also includes some general Photoshop tips and tricks that you might not have known.
This photograph was taken by a lens with some “obstruction” on the front element. Aside from the blurry patch of nastiness in the bottom portion of the frame, the rest of the image looks pretty decent. What do you think the “obstruction” is? A little dirt? A smudge where the photographer accidentally touched the front element? A scratch? The answer is a little closer to a scratch than a smudge… Click here to see the answer
It’s not every where you get to watch and hear someone picking the brain of a National Geographic photographer. The Topeka and Shawnee County Public Library recorded this video interview with photographer Jim Richardson and asked him to share about his experiences and words of advice. Richardson also has an interesting FAQ page on his website that answers a lot of questions about shooting for the famous yellow-bordered magazine.
Photographer Ben Canales created this great video tutorial teaching the basics of shooting the night sky. He goes over how to shoot quick test shots to set up your composition before discussing more in-depth tips and tricks for capturing the final shot, including the “Rule of 600″:
[...] the quickest way to determine the longest exposure that is possible for any given focal length lens, without the stars streaking, is to divide that focal length into 600. (This is the formula for 35mm. Larger formats are laxer, smaller formats more unforgiving). [#]
For example, with a 50mm lens on a full frame camera, you can only expose for 12 seconds (600/50=12) before the stars turn into star trails. It’s a good rule of thumb to keep in mind!
Learning how to control depth of field with your camera isn’t too difficult, but do you know the science behind how it works? This uber-educational 20-minute video lesson gives a thorough explanation of depth of field and the different factors that affect it. It was made by artist Justin Snodgrass, and is also available for download (and in parts) over on his website.
Ovation TV made this interesting video showing acclaimed photographers Albert Maysles, Sylvia Plachy, Andrew Moore, Timothy Greenfield Sanders and Gregory Crewdson answering various questions about photography and sharing words of advice regarding things they’ve learned over the years.
Ever wonder what actually happens between the time you press the shutter button on a DSLR and when the image shows up on the LCD screen? Canon made these two videos explaining how their DSLR cameras work and how they use CMOS sensors to turn photons into photos. You’ll probably find this pretty interesting if you’ve never learned about CMOS sensors before. For a more in-depth lesson, check out the sensor tutorial over on Cambridge in Colour.
