Hello everyone

I would like to hear about your preferences, likes and dislikes regarding the various colours of fluorescent powders with regards to the quality of the resultant capture of the latent print.

I prefer the yellows and greens as the appearance of the capture is green to orange which - IMHO - is better suited to the abilities of the bayer pattern CFA on the camera sensors.

Anyone use pink powders? How would you capture them? Please quote the illuminating frequency, barrier filter colour / frequency and general thoughts on IQ of the capture.

What cameras are you good people using? Please also mention lens combinations and preferences about those...

We typically use Canon EOS 500/550D cameras with the Canon EF-S 60mm macro. We also use the Nikon D700 with the Nikor 60mm Nano-coated lens.

Cheers everyone.

When all the fancy different color powders started coming onto the market, somebody told me "Any color powder is okay as long as it's black." I might add, "and put the lift on a white card."

Colored powders are like fishing lures -- the tackle section of WalMart sells thousands of different lures. If you have a favorite and it catches fish for you, the only thing the other lures are good for is more profit for WalMart. Likewise for powders, they make more profit for the fingerprint supply companies. Whether they develop more prints is a different matter.

Reason I ask is that pink powder requires red light and our cameras do not seem to capture well at the red end of the spectrum...unless I am missing something...which is entirely possible...

Cheers all!
