Being so close to the release of the 2013 Arizona State University Football campaign, I wanted to take an opportunity on to talk about an image that I created many years ago while still a student at ASU. When many people ask me where I believe I crossed the line from hobbyist to professional, I tell them of this campaign, and actually place the beginning on a single image. The fact that the image still lives on my website is a testament to how much I enjoy it and how much it means to me. It is the photo that opened many doors in my career, yet very few people know the background behind its creation.
Check out this awesome exposure triangle graphic found in this Exposure Guide tutorial on the fundamentals of exposure:
When these three elements are combined, they represent a given exposure value (EV) for a given setting. Any change in any one of the three elements will have a measurable and specific impact on how the remaining two elements react to expose the film frame or image sensor and how the image ultimately looks. For example, if you increase the f-stop, you decrease the size of the lens’ diaphragm thus reducing the amount of light hitting the image sensor, but also increasing the DOF (depth of field) in the final image. Reducing the shutter speed affects how motion is captured, in that this can cause the background or subject to become blurry. However, reducing shutter speed (keeping the shutter open longer) also increases the amount of light hitting the image sensor, so everything is brighter. Increasing the ISO, allows for shooting in lower light situations, but you increase the amount of digital noise inherent in the photo. It is impossible to make an independent change in one of the elements and not obtain an opposite effect in how the other elements affect the image, and ultimately change the EV.
If you’re just starting out in photography, do yourself a favor and work through the Photography Basics page over on Exposure Guide. It’s a fantastic resource.

Gamification — the application of game design elements to non-game contexts — is a pretty hot idea right now in the online startup world. More and more startups are introducing things like badgets, achievements, leaderboards, points, and progress bars to encourage users to do things such as visit new businesses, answer questions, and, of course, play games. One particularly interesting application of gameification is in the area of education, using fun to motivate learning.
Video game developers have learned over the years that socially-shared achievements are a great way to encourage beginners to learn new tasks. Taking a page from their book, Adobe has a neat new game called LevelUp that encourages Photoshop learning using the same tricks. Available for CS5 and above, the extension encourages exploration and assigns missions to introduce features and tools that player might never have seen before. Tasks include removing redeye, whitening teeth, and replacing the colors in a photo.
Online SLR Camera Simulator is a neat flash app that helps teach the fundamentals of using an SLR camera by letting you tweak different variables and settings, then showing you what the resulting photograph would look like. It’s a great way for any beginner to become more familiar with a camera’s controls, though nothing beats going out and practicing by taking real photos — though this app would have been a lifesaver before the digital era.
This video by FotoTV features “microstock king” Yuri Arcurs leading a workshop and imparting all sorts of useful tips that you’ll find useful even if you have no interest in doing microstock — things like working with models and capturing emotion. Get out your pen and paper and start taking notes!

Photographer Cosmin Bumbut was given the opportunity lead a photo workshop in one of the least likely places — in a women’s penitentiary in Romania. Bumbat furnished 14 women with six Canon PowerShots plus cards and batteries, and taught them basic photography. The photo workshop began meeting weekly, and within two months, the class had produced some 14,000 images.
The participants achieved what so many professional photographers strive to do: they wove together a very compelling visual story that also has a back story that is just as raw and captivating.
Bumbut has a small batch of additional photos on Punctum (be aware, there is some nudity in a few photos). The photos portray a very intimate portrait of the women and their daily lives from a refreshingly straightforward and honest perspective.
Ever wonder how top photographers deal with their files? Chase Jarvis just put out an awesome blog post and behind-the-scenes video describing his entire workflow from capture to backup. You’ll probably be surprised at how much backing-up his studio does for all its data, and how much storage space they deal with. He points out at the end that all his strategies are scalable, so you don’t need to have infinitely deep pockets to achieve roughly the same amount of redundancy (albiet on a much smaller scale). I guarantee you’ll find this video interesting!
