All images must be high quality jpeg (jpg) image files. Set your camera to the highest possible quality image, use good lighting on your painting without any glass in front of it, and use a tripod for your camera. (If you don't have a tripod, be sure you hold the camera still and that the two vertical sides of your painting are perpendicular with the sides of the image viewer. Having these line up is critical to avoiding distortion.)
You must crop out all parts of the photo that are not the actual painting; do not show mat, frame, etc, only the painting itself. Please save at 300 dpi resolution, with a size of 900 pixels on the longer side of the image (i.e. for a horizontal format, the width should be 900 pixels; for vertical format, the height will be 900 pixels; for a square format both dimensions are 900 pixels.) The upload system will not accept very large files, so you must reduce the native image size to these specifications.
For guidance on how to prepare your images using Picasa, PS Elements, Photoshop or iPhoto, PPSCC purchased these useful Step-by-Step Image Preparation Tutorials created by Christine Ivers, PSA. Click on the title of the image program you wish to use.
