Canon Digital Learning Center Tips For Underwater Photography


Underwater Photography
Ikelite underwater housing for the Canon EOS 70D

The Canon Digital Learning Center (CDLC) posted a long and detailed article about underwater photography. From the article’s incipit:

With its richly colored landscapes and fascinating sea creatures, there are few places more beautiful to photograph than the underwater world. Whether you’re scuba diving among sharks or snorkeling along a reef, the photographic possibilities are endless and intriguing.

Of course, underwater photography can be a little intimidating since it presents unique photographic challenges. But you’ll get immediate feedback with your digital SLR, so you can make adjustments when necessary and it won’t be long before you’ll be showing off images of your underwater adventures to fellow divers, snorkelers and land-locked shutterbugs. To help you gear up and grab those once-in-a lifetime shots, here are some guidelines and tips to get you started.

The MIT Gives You A Free Documentary Photography and Photojournalism Course (Online)

A Free Documentary Photography and Photojournalism Course

This is off brand, still I think many of you might be interested.

The MIT (Massachusetts Institute of Technology) put this class online, the class was originally thought in 2009. The course we are talking about is Prof. B. D. Colen’s Documentary Photography and Photojournalism: Still Images of a World in Motion, published through MIT’s Open Courseware project. The description:

This course is an introduction to the great tradition of documentary photography. Students learn to see the world around them in a new way and produce a documentary project. The course requires reading and writing about photography, as well as doing it on a regular basis. The class emphasis is on thinking about why people photograph, what photographs do and do not mean to us, and on doing documentary work, on telling stories with photographs. This is not a technical class, and it should not be considered an “introduction to photography.” I work on the assumption that any student signing up for the class has at least a minimal sense of the difference between f stops and T stops, and can find his or her way around a camera. While there will be some technical discussion in class, it will be limited.

The course material is pretty rich, with syllabus, readings, assignments, image gallery and more course material that can be downloaded. It’s free, it’s good, it’s there for you – all you need is a bit of motivation :-)

Canon’s New DPP 4.0 Works With SL1/100D, T4i/650D, EOS M, 70D, and T5i/700D Raw Files (with a little trick)

Canon DPP 4.0

A few weeks ago Canon released Digital Photo Professional (DPP) 4.0, a completely new version of  Canon’s well-known RAW conversion software. And the disappointment was big when it turned out that DPP 4.0 supports only Canon’s new full-frame bodies (EOS-1D X, EOS-1D C, EOS 5D Mark III, and EOS 6D). No support for the rest of us?

Slrclub user T.K_Photo (spotted by DicaHub) found a way to make DPP 4.0 work with RAW files from the following Canon DSLRs:

The trick is pretty simple, indeed. All you have to do is to change a value of the EXIF data. It works only for the above mentioned cameras because these cameras use Canon’s “Color Data Version = 10″ (which is stored in the EXIF data). You need a tool to edit EXIF data (ExifTool by P. Harvey is a very good one). All you have to do is:

ExifTool Windows interface


  • select the CR2 file to modify
  • click the “ExifTool direct” button
  • Enter the following command: -Canon:CanonModelID=”EOS 5D Mark III”
  • Ignore the warning

Mac OS X interface


  • Load the CR2 file to modify
  • Go to “Your commands” tab
  • In the “Parameters” box enter: -Makernotes:CanonModelID=”EOS 5D Mark III”
  • Click the “Go” button

Your camera model is still stored in the EXIF, the parameter you are going to change is a specific one. It should also work if you enter “EOS 6D” or one of the other supported FF bodies. ExifTool can be downloaded here, a graphical interface for MAC OS X can be found here. A note: when you download DPP 4.0 you have to enter the serial number of your Canon DSLR. I downloaded DPP 4.0 from the EOS 5D Mark III support page using my EOS 70D’s serial number.

Is it worth the effort? Judge by yourself with the 2 images below, which show the results on a RAW file from an EOS M (image credit: T.K_Photo/Slrclub). The first one is DPP 3.14, the second one DPP 4.0. Head over to Slrclub to see full size images, but even from the samples below you can note that the file produced by DPP 4.0 has more details and is sharper.
