Unlike the previous bows with were made using car headlight this set was made with a hi-power spotlight which shines the light into a nice beam and these bows are kind of unusual because inside the primary beyond the purple inner edge you can see a light colored band and beyond that a dark band. Must be the effects of divergent light or a more dense cloud of mist passed into the beam causing this effect. The enhanced image shows this effect quite well.
Hi Michael,
ReplyDeleteA nice set of photos! I've recently been thinking of having a go at something like this myself. What power spotlight do you recommend? Obviously nothing too under-powered, eh?
Best,
Alec
Well Hey there Alec!
ReplyDeleteGlad you enjoyed my spotlight rainbows. As far as the intensity of the spotlight goes I reccommend anything 10,000,000 candle power or over. Marko Rikkonen can give you ideas. Mine came from Tractor Supply.
Thanks for that, Michael. I've sourced one or two spotlights here in the UK which are relatively inexpensive. Rest assured I'll be giving it a try when the conditions are right!
