Some flowers in my garden.
(Note some comments below are in relation to a problem that i think turned out more to be cos my monitor needed recalibrating!)
----- original description below -----
The first time i've had this noticably happen - i've run out of shades of a colour!
Zoom in on full and look to the bottom left and it's quite heavily pixelated, even tho it's saved on the maximum jpg detail setting.... ! Even the original Raw file shows signs of heavy banding and dithering...
I guess the sRGB* colour gammut is no match for my garden!
(* = or even the adobe colour gammut - i shoot in adobe colour and only convert to sRGB when saving to jpg)
