5DMIII Field Test - High ISO / HDR

[Neon Rosell II]

Finally had time to test the high ISO capabilities of the 5DMIII. Went to LMEP this morning to try how the ISO 25600 photo would look like. And also how an HDR shot on birds would look like. The on board HDR merging merges the 3 different exposure in to a Jpeg file.

Here are several photos to compare the original and the PP'ed photo would look like.

5DMIII + 600 mm f4 IS + 2x Kenko TC, f 7.1 (f14), 1/60 sec, ISO 25600, Tv priority, auto HDR mode, Tripod-Gimbal support in available light. Subject distance 8.0m

FF, adjusted exposure to +0.45 in ACR, Down res for web upload


FF, PPed with my work flow, NR applied on BG


Cropped from PP'ed photo above.


The HDR photo appears to have motion blur, but it was actually due to the not so perfect merging of 3 raw files. Here is the PP'ed raw file with neutral exposure. NR was applied in ACR 6.7 then after my usual workflow was used.

Very nice, Neon! PP'd photo looks good. ISO 25600 seems usable when in-capture exposure is optimized and careful processing is done.

Were you able to do a side-by-side comparison against your 5D2 in a controlled environment?

Wow!! Neon, it won't be long before you can take bird pictures in complete darkness with good results... Thanks for sharing.

Trying to get a better work flow for the new body and here are photos PPed with noise reduction in ACR.

f4, 1/60, +3/4 Ev, ISO 25600


f4.5, 1/160, ISO 4000


f4, 1/160, ISO 3200
