Hi Ash,
After converting to 16-bit with ³Image/Type/16-bit² the pixels will be the
same values as the original, but stored in 2 bytes instead of one. To
stretch the values to the full range use ³Process/Math/Mutiplyв and use a
multiplier of 256. The image may initially display washed out, but if you
do ³Image/Adjust/Brightnes and Contrastв and set the Maximum to highest
value the image will again look like the original.
