Yellow postit on a everyday corkboard.
This picture was taken using a 12,8mp full frame Canon 5D at ISO 200 with a 50mm prime lens.
I have not used any noise reduction on this image, except for the dark areas.
The image has been manually cleaned for small dust particles but has not been filtered.
I develop all of my RAWs in Phase One (Capture One Pro) as a TIF file and with a sharpening set.
