high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range between the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods.
Magic Lantern has developed firmware fad-on that will enable HDR video on Canon T2i (550D) T3i (600D) and 60D HD DSLR Cameras an it’s FREE! We’ve been expecting HDR Video Cameras to become the norm for years and this is a big leap in that direction. So much effort is going into 3D camera development that HDR isn’t getting it’s fair due. This firmware ad-on solution will likely turn a lot of heads and start a movement in the industry toward HDR video cameras development & design.
The firmware ad-on does not overwrite Canons camera firmware, it ads on to it. The Free firmware ad-on can be downloaded here http://magiclantern.wikia.com/wiki/Release_2011Dec22
HDR imaging is a technique that combines images with a range of exposures to provide higher range of detail from shadow to highlight. Photographers were doing this manually long before digital imaging, but digital solutions make it much easier and feasible, even for video. HDR Video has been accomplished by using multiple cameras in the past, but I’m not aware of any mainstream solutions like Magic Lantern’s firmware will provide. The firmware switches exposure between frames and creates two videos which can later be edited back together to to create a single High Dynamic Range Video. Many advanced still photographers are accomplished HDR technicians. The thought of combining 30FPS Video is mind boggling but today’s computational imaging hardware and software is capable of such mind boggling feats.
Magic Lantern’s first firmware add-on enhanced the sound and video capabilities of the Canon 5D Mark II. Sadly, the HDR Video firmware ad-on will not support the 5D Mark II or the 7D. Below is a video outlining the capabilities of the Canon 5D Firmware add-on. This video explains how the firmware ad-on works.
