Thanks Discus,

Yes, with the hand held I often only noticed back on the PC. With the DSLR on a tripod sometimes we have the images coming straight to the PC before the shutter goes off so we see them quite quickly. We can also control the camera settings from the PC but we usually find that easier to do direct on the camera.

Thank you RosieC. I've let it dry out in the past but in my new setup I think I'll be able to keep it more moist. Hopefully it will recover. I will also try to let it cool down in the winter. :bowing
