Some pictures taken at ISO 1000 1/640 sec using a borrowed Canon 7D to investigate how much noise there is at higher ISOs.
The images were fairly noisy but Neat image has done a pretty good job removing the noise.








The frozen water was an almost pure cyan colour. The sky at this stage was grey as there was still high level fog.
A little later the fog lifted and there were glimpses of the sun. I changed to the 15mm fish eye as I kn ow it will shoot direct into the sun with no appreciable flare.
