Bit bored at work. This happens, like most places I guess. All or nothing.
Thought I would give ISO 25600 a go.
EM1 Mk2 (I have better cameras), 40-150 f4 at 150 wide open.
C1 only. Grainy, unsurprisingly, but still sharp and the colour is workable.
With some ON1 NoNoise love.
Compared, they look similar at these sizes, but at 100% there is a clear difference.
I got up close to the actual sticker and the roughness on the edges is from the ticket printing. Fully useable in print and even on screens.
A bit more processing. Generally, the best process for me is to do most in C1 before dropping the file over the ON1 as a tiff, then exporting out of ON1 pretty much on standard settings.
