(4) PhotoGraV combines the enhanced image with the dithered image before thresholding the result. 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. (3) Although the following two functions are provided by other graphics programs, only PhotoGraV allows you to adjust the functions' parameters and see the effect on the simulated engraving in near real time. 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. (2) PhotoGraV provides a diffusion dithering process that has been designed specifically for laser engraving. PhotoGraV's simulated engraving is not merely an overlay of the input photo on a simulated engraving material but rather is produced by a Power/Lens model using the actual binary image that you would eventually send to your engraver. Further, PhotoGraV's interactive 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 simulation capability provides a way for you to inspect the appearance of the final product before you actually engrave it.
What can I do in PhotoGraV that I can't do in these graphics programs?Ī. I'm currently engraving photographs that I've processed in PhotoShop (or CorelDraw or PhotoPaint or. Samples | Q & A | Downloads | BUY IT NOW !ġ. Acrylic Printing: Awards, Plaques, etc.
