Thanks Jase.
Plenty of food for thought.
When I process i initially do all my callibration and stacking in Maxim then do a linear stretch to Max Pixel and save as tiff; after which I bang away in PS2. Are you saying this is wrong or that i have clipped the white during the processing. I may have been a bit over eager with the curves
