The driver for the Epilog 24TT has a "Photograph" setting under Raster->"Basic Options". Does anyone know how this differs from Raster->"Basic Options"->"Clip Art"?

Do I need to convert images to 1-bit images? Or will driver take care of dithering for me? I've tried it out, but the results don't seem to be all that much different from Raster->"Clip Art".

If anyone has a 24TT and has any tips for photo-engraving, I'd much appreciate it.

Thanks,
Dave
