I have been trying out my refurbed 7D from Canon UK. Another awful day in the UK, so cannot attempt any lens calibration.
Anyway a vixen has a litter in the next garden and she likes to sit peacefully on the shed roof. This is one of the pictures at 1600. I happened to looked at the images as well as the others in the latest DPP and ACR67 and was surprised at the really awful blotchy noisy image. Is this what I should expect at ISO 1600?
Default sharpening in ACR and DPP, no noise reduction. Image was slightly undrexposed, so I raised it in both applications. THe ACR seems to be sharper, which accentuates the white pixels.
1/400 at F6.3 with a 100-400 at 400mm supported by a window sill
These are at 100%
