Submitting Panorama Images
Image size: Your images should be no more than 1400 pixels along their longer dimension. Only horizontal panoramas will be accepted (no vertical). They should be 1400 pixels wide and no more than 700 pixels high.
Image size: Panorama prints can be as large as 18” x 36” (a ratio of .5), mounted on a mat board up to 22” x 40”. If for example you choose a panorama print of 24” wide it should be no taller than 12”. Vertical panoramas are ok. Note that in both cases (Digital and Print) panoramas may be created by stitching together images or from a cropped image.
