Canon 1D Mark IV - A hands on Review

[Sabyasachi Patra]

ISO 3200:
This cormorant flew and landed near me. Settings used ISO 3200.
Processing: Image processed in Lightroom with the default noise reduction ie. (Luminance at 0 and Colour at 25), default sharpening, brightened by 1/3rd stop and full frame image. Remember, that brightening or opening up the blacks results in more noise.

Verdict: There is noise visible in the blacks. However, this appears like the ISO 800 of my 1D Mark II. I will do some further testing on this. Also, it may be noted that if you miss the exposure and pull up the shadows a lot, then it may be a different story. If your exposure is right, then you would be smiling.
Overall, the files are great. They require very less processing. The noise is well controlled. I won’t mind using the ISO 3200 if required.
(I haven’t tested the high ISO noise reduction functions. That has to wait for a later date).
