If you’re a fan of learning things through Khan Academy, then you might enjoy learning about how ISO works in this similar-styled tutorial by Dylan Bennett. Bennett might not have Salman Khan’s soothing voice, but he does his best to break down the magic of digital camera sensors into easy to understand ideas. For a more detailed and comprehensive understanding of how things work, check out Cambridge in Colour’s excellent tutorials.

In a paper published in Science this week, Japanese researchers reported on a discovery that jumping spiders use a method for gauging distance called “image defocus”, which no other living organism is known to use. Rather than use focusing and stereoscopic vision like humans or head-wobbling motion parallax like birds, the spiders have two green-detecting layers in their eyes — one in focus and one not. By comparing the two, the spiders can determine the distance from objects. Scientists discovered that bathing spiders in pure red light “breaks” their distance measuring ability.
Phonar, the free and open undergraduate photo class we wrote about a couple months ago, is now underway. While the physical class can only be attended by students at Coventry University, the general public can take part through the assignments and recorded materials shared through the website. Here’s the first assignment that’s due on October 13th:
Garner a portfolio of 8-10 images from different photographers whose work inspires you. Choose carefully, as though your edit was going to appear as a spread in a printed magazine, you may choose to lay them out as such if you wish, with attention to scale, pace and flow etc.
The portfolio must directly address a theme of your choosing – it could be a personal theme or a topical one, the choice is yours.
Participating is a great way of getting a taste of what taking an undergraduate photography course is like.
The Art Institutes, one of the nation’s largest for-profit school systems where people can receive an education in photography, has come under fire. Last month, the US Department of Justice filed a massive lawsuit against the company behind the schools, Education Management Corporation, accusing it of fraudulently collecting $11 billion in government aid by recruiting low-income students for the purpose of collecting student aid money. Whistleblowers claim that students graduate loaded with debt and without the means to pay off the loans, which are then paid for with taxpayer dollars.
Marc Levoy, the Stanford professor behind the “Frankencamera” project, teaches a course on digital photography called CS 178. The class website is a treasure trove for anyone looking for some great free education in photography:
An introduction to the scientific, artistic, and computing aspects of digital photography – how digital cameras work, how to take good pictures using them, and how to manipulate these pictures afterwards. Topics include lenses and optics, light and sensors, optical effects in nature, perspective and depth of field, sampling and noise, the camera as a computing platform, image processing and editing, history of photography, and computational photography. We’ll also survey the history of photography and look at the work of famous photographers.
#phonar, short for “Photography and Narrative”, is a free and open undergraduate photography course run by Jonathan Worth at Coventry University in the UK. Worth spent nearly 15 years as a successful commercial portrait photographer in New York before taking this part-time teaching position, and invites some pretty prominent photographers to guest lecture in the class. Participants have access to recorded lectures, assignments, and special discussions.
You can check out the material from last year’s class on the course website, or participate in this year’s class starting in October by signing up here. There’s also a second course in the Winter called #picbod. Yay for free online education!
Canon created this short but interesting video showing how its SLR cameras evolved from the Canon Flex in 1959 to the latest DSLRs that currently dominate the industry.

Shooting in JPG mode is convenient because you instantly have a file you can throw onto the Internet, but if you’re serious about photography, you might want to think about shooting in RAW if you aren’t already. The reason is that only shooting JPG is the equivalent of letting the camera make a print for you and then tossing the negative — something film photographers would never do. Here’s a simple diagram by Haje Jan Kamps and Reddit user jannne to help you understand the differences.
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.

Google’s new Books Ngram Viewer is a cool new site that allows you to search for words and view a graph of how the usage of that word has fluctuated over time. A quick search of the word “photography” in books published between 1835 and 2008 provides a pretty interesting look at the history of photography.
