Infrared and IDP

From the outset IDP has seen the use of infrared and other specialist photographic and image manipulation techniques. Digital infrared photography is a valuable tool in the arsenal of the digital photographer, adding value and increasing knowledge and understanding of an object's history and usage. It cannot always produce the results we would hope for but the technique is non-destructive, so even if it reveals only small amounts of hidden or obscured information, it is worth the effort.

Infrared imaging and photography can reduce the need for invasive and expensive conservation and cleaning, helping to maintain the historical integrity of the original object virtually removing wear and tear by digital means.
