Thumbing with IR

I don't know how many of you know this, but most digital cameras can see the near infrared wavelengths commonly used in remote controls (and which also frustrate sunset shots without an IR cut filter).

I was curious to see if I could spot any anatomic details (blood vessels, tendons) in my left thumb, so I took my older of the two Nikons I own (the Coolpix 2500 in this case), shined a remote control through it and...not quite the "T-ray imaging" featured on 'Red Planet', but what the hey!

    IR exposures
    That Sony of yours may be more sensitive to IR by design, which would likely mean reasonably short exposure times.

    The IR Thumb shot I took with the Nikon E2500 took a whole second--the longest shutter time that camera will do (my Nikon E5400 can stay open for as long as 10 minutes if I want).

    I'd like to see some 'night mode' shots from your Sony!
