The Usual Suspects


UV Paint

Spray Painting Street Art Sam wrote: I have just started experimenting with photoshop but my prefered media is acrylics, graphite and charcoal along with mixed media. I'm putting a poster together at the moment in a 1960's psychedelic theme. My question is, is there any way to make a poster like this luminescent under an ultraviolet light bulb, the way the old hand painted psychedllic posters were? What kind of media would I use? The short answer is: wow! I love the idea. the long answer is try: http://scientificsonline.com/product.asp_Q_pn_E_3081643 (Edmund Scientifics) they aren't cheap and a lot of scientific suppliers won't sell to just anyone (unless you have a letter-head at a Univ or such -- always afraid of scaliwags and such). Unfortunately, the florescent effect is mostly just a sort of side-effect of the material. In chemistry there are specific reactions that you can measure (but of course then you purchase a UV spectrometer for $$$'s to do sci research). The Edmunt $30 light looks good. Here some of my thoughts on it: 1) UV light is (slightly) dangerous to the eyes. If you are using something like that light from Edmund Sci it should be ok. There are a few sites like: http://www.club-t-shirts.com/en/accessories.html But, then they don't want to sell you the chemicals. 2) The chemicals usually look white or grey-ish and "just happen" to floresce under uv light. You may have to provide SOME ambient light to high-light the traditional colour work (or ink on paper, etc) that you are doing. And then use the UV lights to pick up the florescent paint. What i'm thinking here is to use the flouresent dies to high light certain lines. Think of Lee Krasner's "cubist/surrealist" drawings, or Paul Klee's "cxartoons". Apply your normal media and then hgih light it with the uv-paint. 3) Fabrics (i seem to recall LINT from cotton t-shirts and some poly-ester fabrics) are flourescent as well. You'll have to experiment. You MAY find that crayons, pencis, and other traditional materials actually flouresce as well. You can never tell - it all depends on very specific chemical structures of the materials. And these are usually organic dyes or other materials that just happen to flouresce. LET me know if you find some stuff out. Again, be careful since a lot of paints or materials are toxic (just like our "good friends" Cadmium and Barium paints - v. toxic (espeically as a dust when scrap-ed or sanded!!!). Also, you can experiment with painting with somethings and covering them with varnish, gloss or matt medium, etc. But, i would guess that covering the UV paint or material will mask it and may LOOK transparent bu the gloss medium or varnish would cut off the UV light frequencies. Like i said, the first step is to get a uv lamp and then experiment with materials that you already have at hand to see if they flouresce. Then to "somehow" apply them to other work; i'm thinking "glitter" or paper collage here. As with ALL LIGHTING - think in terms of both static and moving sources. One UV light could be mounted on an oscilating fan and slowly waft back and forth, or even be used with revolving mirrors and such. And of course a KEY here in an installation space is SAFETY (and durability - like all "public space" scultpure expect a LOT of maintenence. Sounds like a way cool project (or as we old hippies are want sey, "Far out!!" take care and stay in touch, i'll try and get a uv lamp and do some experiments myself - i have (somewhere) a UV secret pen that i got with the "Get Smart" DVD. - frank
