Does anyone know of a way to convert a negative image (typically a B&W or even color negative photographed on a copy stand with a high resolution camera and macro lens)to a positive image in Lightroom?
We make a lot of these exposures from exisitng negatives and would like to automate the process in lightroom as it would faster than working in Photoshop.

It's much easier for B&W than color.
Here's what you do:
Lightroom v2.0:Develop Module
Under the "Tone Curve" Panel, next to the Point Curve drop down menu, choose "negative".
That will show you how it's done for B&W. With color, you'll need to futz around with the HSL sliders to correct for the orange mask.
Or you can photograph your color negatives with a matched bluish-green light source or CC filter to mitigate the orange mask before digital capture.
