A method for generating a presentation of a region-of-interest within an original image for display on a display screen, the region-of-interest being at a depth within the original image and being occluded by a portion of the original image at a lesser depth, the method comprising: applying graduated transparency to the original image to generate the presentation, the graduated transparency reducing occlusion of the region-of-interest by making transparent at least some of the portion of the original image occluding the region-of-interest, the graduated transparency when applied renders within the presentation a focal region having a maximum level of transparency at the depth of and for the region-of-interest at least partially surrounded by a shoulder region where transparency decreases with lessening depth from the maximum level to that of the original image surrounding the shoulder region to provide context for the focal region with respect to the original image; and, displaying the presentation on the display screen.
