Any picture can be converted to monochrome black-and-white or sepia tints. The same original can have quite a different 'feel' to it depending on the tone of the final print.

The originals on the left have been restored and then reproduced in in a modern monochrome and then in sepia finish on the right.. It is possible to use other tints as well called duotone as shown here in shades of blue. These can be reproduced in high quality full gloss photo posters of 36" x 24"
and make terrific works of art
