Scan the album cover in segments. A 12 by 12 inch square piece of cardboard will not fit on a traditional flatbed scanner designed to scan 8 1/2 by 11 documents. Use the ridged border of the scanner to keep the cover square as you scan “slices” of the image. Up to four scans may be required to capture the entire album.
Open the individual image scans in software designed for photo enhancement and restoration. Adobe Photoshop and Corel Painter are among the most popular software titles that will provide the restoration tools needed.
Create a master file canvas sized to the original album cover. The image size should be 12.375 by 12.375 inches square.
Select the usable region from each scanned image and copy the image into the master file.
Orient the image regions copied into the master file so they overlap to form a mosaic of the entire image.
Adjust the individual layers by rotating them as needed so each layer segment is perfectly square with one another.
Zoom into the exact point where each image meets. Use blending tools supplied by the software to conceal image borders. The Airbrush and Photoshop Clone Stamp tools are particularly effective at masking edges while maintaining image continuity.
Merge the individual layers into a single final image layer when all adjustments have been made to accurately recreate the album cover.
