It has - the 'image brightness' setting sets both gamma and brightness/contrast according to some fiendish Hamrickian scheme. I still preferred them as separate parameters, but that's the control to twiddle with - in practice it works well - to achieve a scan which does not clip either end of the histogram. You'll also want to set VS white point to 0.01 and black to 0.0. Like I said, aim for a rather pallid preview scan which exhibits neither full blacks nor whites. Use the levels shadow and highlight eyedroppers in PS to adjust to taste. Regards Tony Sleep http://www.halftone.co.uk - Online portfolio & exhibit; + film scanner info & comparisons
