Jumping into UV fluorescence
Snoogly:
In another sideways step into images vs photographs I am in the early stages of indulging in UV fluorescence. It’s ironic that the used Speedlight only cost ¥2000, whereas the filters cost **##**! Still waiting for a 62-67mm step ring to mount the two filters.

I cannot create a totally dark ‘studio’ anywhere in my home, so I will be limited to nighttime excursions outside. But is total darkness really necessary? Curious to hear from aficionados who capture UV fluorescence images out in the wild.

If you are into UV fluorescence and not the reflected UV photography, you would be better off getting a 365nm UV flashlight at Amazon or eBay. Those flashlights seems to come with the UV-pass filter glass at the front. Just keep your eyes off of their reflectors and be careful of the treatment and choice of the 18650 battery.

Head over to our 'sister' site www.ultravioletphotography.com and dive into the vast amount of stuff about UV-induced and other kinds of amazing fluorescence found there :).
One or two UV 365mm LED torches are pretty cheap on eBay and you can do a lot of UVIVF captures with such simple light sources. You only need filtration to block UV itself -- anything else is pretty standard photo gear.
In general, using a flash is not a great idea since you have little perception or control of the fluorescence induced.
The fluorescence of lint and dirt particles will amaze, or annoy, you depending on how clean you considered your subject to be before actually capturing the fluorescing image. Be warned.
Hints: lots of plastic material found in your household will fluoresce in bright colours. An old classic that never fails is a bottle of tonic water.

Indeed, yes! Here you see some of my humble proof of many things in your household capable of fluorescing. :)
