Recommended Posts


managed to get some phone shots of the screen


first do the single stack and tuned it so ithe image starts to dim and the histogram peak gets sharper


you may have to adjust focus











then add the d/s

and increase exp and tune to give a nice sharp histogram again and tweak S/S and D/S slightly to give as uniformly  even brightness image as poss


drop gamma to give a good contrast and increase zoon to focus up



increase gamma back to 1

and image away checking focus as temp changes
