Opened my saved blend file after the last tutorial, and there was no backdrop image. Re-selected the source file in one of the Image nodes, and it appeared except that most of the image is missing. Only a small rectangle along the bottom is visible. Changing the Draw Channel to Color shows most of the image as black. The Combined, Alpha, and Depth outputs of each of the three image nodes are all confined to this same small area. Grateful for any help!
