We request that you use the standard Submission Form (PDF format) >> (print form then fill in) for data on slides/digital images submitted. We need accurate and consistent information for the data base. We also need your signature for release of the submitted slides/digital images.

Digital images should be very high resolution TIF files. Numbers will vary with the particular scanner/camera used, but resolution of 1350 pixels/inch, file size of 1 to 3 MB, and image size of 1024 to 768 pixels for width and height are common parameters. These images may be submitted on CD.

We return 2x2 slides that are not used. In some instances, sufficient examples of the condition or image have been entered into the slide bank and additional examples are not necessary. We do want multiple images and views, but not in excessive numbers. From previous experience, we know that not all slides will be transferred successfully during the digitizing process. Due to reproduction, transfer and other manipulation of images from the original slide during the process, details and visual acuity may be lost. Thus we attempt to eliminate problem slides during the selection process. We do not label each slide's problem but following is a list of some of the common problems encountered in slides that are returned:

  • Images that contain primarily red tints (a constant problem in tissues with blood or autolysis).
  • Images that have incorrect exposure (are too dark or too light).
  • Images that are not in sharp focus.
  • Images that are cluttered and not focused on a specific detail, lesion, area, etc.
  • Images that have distracting backgrounds (color distraction, clutter, flash highlights, etc).
  • Microscopic images that are not shot at sufficiently high magnification. A series of magnifications are needed for orientation, but images shot at less than 25X or 40X will not show needed detail on the digital image.
  • Images that are in vertical rather than horizontal format
  • Images that do not have a small, surrounding border of space around the lesion or area of interest (a small portion of each image may be lost at the margins during the transfer).
  • Diagrams with accompanying print that is too small to be read easily by the unaided eye (the print will not be visible on the digial image either).
