My red roses are severely wilting at present. However, in a pinch they still can make the motif for whatever photographic gear is trained upon them. In this case the enigmatic "Enigma" 125mm f/1.2 mirror lens on my NEX-5N monochrome. Added a dab of colour later as the roses are, or at least, were, red once upon a time. This is a full-spectrum capture, implying a mix of IR and visible light. No significant UV present as I'm indoors behind triple glazing.
