For best quality, they have to make slides from negatives, with digital
duplication you can get excellent result. You can even get a result that is
much better than original with some software editing, contrast and color
adjustment...etc. I have a Polaroid Propalette 8000 at home that can output
slides up to 8000 lines resolution. You simply can't distinguish whether the
slide is output from the machine or shot with a camera.

>Last week I attended a slide show of underwater photography taken between

>all been taken with single or multi flash lighting at depths between 25 and
>100 feet. The photographer / diver mentioned that they had been taken using

>
>2. To what extent would or could the slide photos be a guzzied up effort

>3. How common is print to slide conversion for these awe inspiring slide
