High definition video recording is a standard feature on digital cameras these days. If you’ve never really understood the terms 1080p, 1080i, and 720p, here’s a short and sweet explanation that’ll bring you up to speed. Benjamin Higginbotham of Technology Evangelist describes the differences between varieties and why you can consider 720p “better” than 1080i.
Even if you have a good command of using f-stop numbers and properly exposing photographs, you might not understand the math behind why f-stop numbers are what they are. Here’s a simple (albeit math-filled) explanation by Dylan Bennett of what f-stop is, including a simple trick you can use to memorize the f-stop scale.
Last week, a collection of 36 prints by William Eggleston was sold for $5.9 million at auction. The top ten list of most expensive photographs ever sold doesn’t contain a single work worth less than a cool million.

Next Media Animation is a Taiwanese company that regularly creates animations that report on news stories and current events (here’s one they made after the death of Steve Jobs). Earlier this week they released the animation above that explains the rise of Instagram and it’s impending arrival on Android. The style is very… unique.
Here’s an interesting 12-minute video that offers one explanation into how the world of art works. Even if you don’t agree with the philosophy and worldview described in the video, it’s still an eye-opening tour of the different things that influence and power the mysterious world of art.

The woman was upset because she thought that $3,000 for a wedding photographer was “wack” because all we do “is hang out at a wedding taking tons of photos and editing them” and that we are “making so much money its crazy.”
I first read this post earlier today while I was running errands and my head almost exploded. I immediately started drafting a horribly mean and punishing response in my head, but by the time I got home, I realized that this is probably a common misconception and that maybe I should try to explain why photographers charge what we do for our work.
Confused about what Google’s new Photovine photo sharing app is all about? Here’s a short video published yesterday that explains the service without blinding us with hairy-chested dudes. “Instead of just posting a photo, you plant it and watch it grow.”
Aside from the fun-factor of “vines” planted for random topics, it seems like the service could be useful for spreading images of real-time news stories (e.g. protests, disasters, etc..), similar to what Twitter does with text and hashtags.
