Not all film recorders will yield the same sharpness on a slide or negative, as the size of the spot of light that illuminates the CRT varies from manufacturer to manufacturer and from model to model in any one manufacturer's line. PhotoGraphic Specialties uses Lasergraphics LFR Mark III film recorders with Extended Density Range to give you the sharpest slides, whether you order 8K OR 4k imaging. We do not offer 2K imaging as there are no benefits to you in either cost or speed at this resolution.
