it allows you to shoot fast and not touch the camera's physical shutter. A Promote control or similar is an absolute must for programming your brackets. For those, the dynamic range is more limited and you can get away with 4 exposures. At the other end of the exposure spectrum you have overcast, cloudy days. For night shots, you need to add one or two long exposures at the bottom end to extract detail from the super-dark shadow areas and the night sky. For daylight scenes, 6 brackets are usually enough to capture everything.

From there, I step up by 2EV until I get all the details out of the shadows. My bracketing is always based on the given lighting conditions, but normally I start with the fastest possible shutter on the MK II (1/8000s).

It takes a bit of practice to get a hang of this technique, but it works! I didn't want to see a tripod visible in my nadir and so I added another capture with the tripod moved away from the original position and the center arm of the Nodal Ninja flipped. In summary, that's 8 pictures in total to cover a full 360x180 degree HDR. Later, I added a 'zenith' and 'nadir' shot to fill in the tripod location and fill a gap at the top of the panorama. With the 15mm, I was able to take a set of 6 images (with a 72 degree offset) to cover the entire 360-degree horizontal range, and still have enough overlap for high-quality stitching. I experimented with several, but in the end the 15MM was a clear winner. The lens choice was a bit more complicated. It was the best camera camera on the market at that time, and remained so for a long time after. Despite this, I was committed to getting the best out of my image-based lighting renders and so I set out to teach myself.Ĭamera/Sensor choice was pretty clear from the get-go: Canon's EOS 5D Mark II.

On top of all that, almost nobody was using gamma correctly (and many still don't!). The Preetham 'physical sky' models that many render engines had implemented were similarly unimpressive and did not produce the results I was after. Back then, a chrome sphere was the standard method for HDR capture and the limitations of this method meant that they were not suitable for sharp, detailed reflections. When we started using HDRs and image based lighting back in 2007-2008 the quality of most HDR images was poor and there was a very limited selection to choose from.
