Hello Fisher - good to hear from you again, and look forward to your pictures of a 'glowing green fish
Many of the 'reaction' pictures that I post, have been taken with the torch in one hand, and the camera in the other - shouldn't be a problem unless you have the DT's
, although you may find that a quality torch performs better than a very small key ring type (they would work, but produce a smaller beam). You could also try asking someone else to hold the torch whilst you snap the pictures. I don't really know why it should be considered ....
VERY difficult taking photos of
glow in the dark - I would think it is a lot more difficult in the daylight
But a little intrigued that you have a 'blacklight torch' - as blacklight is usually reserved for the tubes (they have a dense blackish coating on the glass, so that when in use the viewer isn't blinded by the u.v. light - and its always amusing to see the U. glass light up from what appears to be just a black glass tube.
Can assure you that if you get a reasonable quality u.v. torch, you'll be a dab hand in no time at taking pictures with the torch in one hand and the camera in the other - the only thing you need is the dark
. See here for torches....
