Hi The IR spectral properties do make quite a difference.
Some time ago I was involved in research into vision systems for incorporating into cars, to improve the view in fog/rain. We found that depending on cameras used the brightness of fabrics bore little resemblance to how your eyes perceived it. Some bright clothing that you might wear to be more visible when walking at night was almost black with IR (not very helpful :-) ... the good bit was I got to drive round a Jag with a full military type head up display fitted. The IR sensitivity effect has also led to a market for IR filters that allow you to "see through clothes" with cameras I've got some links to IR stuff at <http://www.northlight-images.co.uk/links.html#3> bye for now Keith Cooper Northlight Images http://northlight-images.co.uk Photography - Digital Imaging - Apple Mac Consultancy Tel +44 (0)116 291 9092 Mobile +44 (0)780 162 9397 =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
