We've continued our preliminary testing of the Canon EOS-1D Mark III pre-release camera, now with high-ISO results under incandescent lighting, and some examples of what its unique High Tone Priority mode does.
In response to reader requests, I shot some 'indoor portrait' test images with the Canon 1D Mark III, to see how its high-ISO performance held up under lighting with a decidedly non-daylight white balance. (Household incandescent lighting, about 2800K.) Crops compare the results with equivalent images from the EOS-1D Mark II N. See the Incandescent Lighting sub-tab on the review
I also spent a little time playing with its enigmatic High Tone Priority exposure mode (C.Fn.II-3), and was again duly impressed. HTP is only available at ISO settings of 200 or higher, apparently due to pixel charge-capacity considerations, but it does an amazing job of holding onto detail in strong highlights. This strikes me as very much what Fuji was trying for (and achieving) with their SR sensor technology. Now, Canon's done the same, through the simple expedient of limiting the ISO to 200 and above, and twiddling with the tonal translation a little. Very impressive, check it out!
