We are the UK distributor for this product. Parameters controlling this process are user-adjustable in the interactive mode. PhotoGraV applies a simultaneous smoothing and edge strengthening to the image. PhotoGraV automatically 'stretches' an image's grayshades over the entire grayshade range but also provides user-controlled adjustment of clipping and gamma parameters and histogram equalization in the interactive mode. Other common halftone patterns are also provided by PhotoGraV in a user-adjustable form but, for most images and materials, these 'standard' halftones are not nearly as powerful as the adjustable diffusion dithering. The adjustable density of the diffusion dithering is in addition to the more standard grayshade adjustments that are also provided by PhotoGraV. Further, the density of the diffusion dithering is user-adjustable and has been optimally pre-tuned for the engraving materials supported by PhotoGraV. Further, PhotoGraV's mode allows you to adjust any of PhotoGraV's processing parameters and to see the resultant effect on the simulated engraving in near real time a second or two. PhotoGraV provides a significant number of advantages over general purpose graphics programs for laser engraving photographs: 1 PhotoGraV's capability provides a way for you to inspect the appearance of the final product before you actually engrave it.
