As an laternative, you can run Process/Enhance Contrast, after setting Saturated pixels to 0.0 % and checking only the Normalize option. In this way the values are stretched to cover the full dynamic range.

Subject: Re: convert 8 bit to 16 bit
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/MutiplyŠ² and use a multiplier of 256. The image may initially display washed out, but if you do ³Image/Adjust/Brightnes and ContrastŠ² and set the Maximum to highest value the image will again look like the original.
