I came across this website that offers a Photo to Canvas Printing service. They can convert any image whether it is from a digital camera, a photograph, 35mm slides and transparencies. They offer photo restoration as part of the service and can correct any imperfections such as red eye. They can also combine several images for you, convert a picture to black and white and restore damaged pictures.
If you want to combine a lot of photographs you can choose from several options, one of which is a memory board containing as many as twenty small photographs. I think this option is a really nice idea and would make a really nice personal present. Other options available include a filmstrip effect where you can combine four of five images separated by a film strip.
They offer the prints on a wide range of finishes including art paper, art canvas, photo paper and clear film. A family and friends package is also available so that if you order a main piece of art, you can have an additional two A3 duplicates for an extra £100. All the prints are offered with a full money back guarantee so that if for any reason you are not satisfied they will issue a full refund.
