While digital photos are preferred for both the quality and ease in transfer, you may certainly send us your paper photos to be scanned in at the highest quality (600dpi). Our scanning process automatically performs basic color adjustments as well as dust and scratch removal to assure the best quality possible for your video slideshow. We can also scan negatives as well as slides. Photos that have been cropped at odd angles, used in scrapbooks, or have extensive tears or water damage are not recommended for slideshows. In addition, having a variety of horizontal and vertical photos will give more dimension to your slideshow.
