Infrared and Ultraviolet clip on flash emitters.

I was doing some night shooting, the UV dosen't seem to mind to much what time of day it is. Day Time UV is only 10 percent of light from the sun the way I understand. I have been looking at covers for speed lites that have two panels of IR with the other side UV. These are pretty cheep for what they do and if any one knows any places that sell these baby's I sure would like a little help. I do like what I have been able to do and it will be at least another year before I can buy some better flash's for my little UV camera,,,,thanks peeps, you are my only hope.

Re: Infrared and Ultraviolet clip on flash emitters.

They work like a diffuser and slide down over a hotshoe speed lite. They have two flat sides facing forward and each one opposite a few degrees of each other. One side IR the other UV, I am trying to get a feel for the limits I face in accessories. Hi Chrisa, thanks for your response, I get fed up searching on the net some times. I know there are some enter search rules for better searching but I don't do very good I need education.

Seen these LED illuminators ? Not quite a diffuser - could not find them.

Phantom lite Infrared, Full Spectrum, Ultraviolet illuminators

They are also available on Amazon.

Re: Infrared and Ultraviolet clip on flash emitters.

Wow, now that's a good search, and the prices aren't all out of wack. These look better then the flash lite I used to experiment with. Thanks Chrisa, I got that marked.

Re: Infrared and Ultraviolet clip on flash emitters.

Yeah they look interesting - note you need an extra bit to get them to act as a flash. Might be tempted to get one to try with IR myself at somepoint.

Re: Infrared and Ultraviolet clip on flash emitters.

Hi Chrisa, that's temping to get some IR light I think would isolate at night real well. The test's I performed with my lights that work pretty good didn't show any shadow over kill. So last night I have been wanting a 90 degree viewfinder for years, went on and picked up one of the illuminators. I got the UV and an all spectrum with the hotshot bracket. It says you can use it by it self or with the camera. Don't know what is what at the price but there is just not that much out there for beginners like me. All I really need at this point is a little extra light. Using the 9 volt battery it might work out fine. Thanks for your input, it is welcome anytime,,,

Re: Infrared and Ultraviolet clip on flash emitters.

Good search Chris It's strange that this didn't come up earlier, as LEDs can be very specific in their spectrum output and useful for this kind of work. Better than the article I read where a guy from Germany had gone as far as removing the yellow coating from the xenon flash tube in order to get better UV output. Only problem is the intense power delivered by flash compared with the LEDs but sounds interesting enough to experiment with.

Re: Infrared and Ultraviolet clip on flash emitters.

Let us know how you get on with them. I'll be interested to see what you make of them.

Re: Infrared and Ultraviolet clip on flash emitters.

This is one I've been looking at for awhile, I just didn't know how to paste on my pad. Quantum Instruments QF80 – Qflash UV/IR Wave Reflector | Camera News & Reviews

Looks like down farther in the review that they have some smaller ones. I have one speed lite a 430 II. I really don't mind after Christmas getting something like this.

There are those quarts lenses that cost as much as a house and they are just something to dream about. I still have not been able the find the ones that slide down over the speed lite, I did not mark them and can't find them,,geezzzzz

Re: Infrared and Ultraviolet clip on flash emitters.

Photography of the Invisible World Klaus Schmitt is really the go-to guy, he has a lot of info kicking about on cheap (affordable) uv capable lenses and such,.

I think if we assume the camera is set to record a certain spectrum (uv or IR) then really you can use the flash as it is,. since the rest of the light won't be captured,. i.e. I'm not sure I see much value to filtering out the visible spectrum from the generated flash at source (unless you are doing covert photography and don't want the subject to 'see' the flash)

Re: Infrared and Ultraviolet clip on flash emitters.

Hi silver,
Thanks for the link, I think your 2nd one and the person klaus is the real deal. I picked up his transition between film and digital. His recommendation on Nikor lenses is an option for me as adapters work nicely for canon. I might loose auto focus but I haven't used it yet for my most successful pictures.
My interest in the Q80 flash is that I have 3 invisible light cameras. One of them as far as I understand a UV/ IR conversion will let 20 percent across the spectrum pass. The others near IR and near UV both reflected and adsorbed light. I could have missed something but the flash passing these 3 fields of light or just the two on the ends would give better light or faster shutter speed on the UV considering 10 percent daylight from the sun. I did get caught off guard with the UV but I love the look of it. I have read about a chapter from klaus, he seems to have a whole book. Anyway I will have these brighter lights by this Wednesday. I should get a better feel for it. I have shot at night with just one light that has 12 led's, these coming have much more. I have not tried using the camera flash and will give it a go. thanks for your helping hand I've takin a grip on everybody that's offered. I have learned so much about light the last three years and it's very interesting looking and comparing what we see and do with it. I love the fine art look to invisible light.

Re: Infrared and Ultraviolet clip on flash emitters.

there's a group (it's been a while since I was there) of very ardent UV shooters at nikongear Invisible Spectrum Zone (UV/IR) - Nikongear.com - Klaus posts (or posted) there and also people like Bjørn Rørslett / Ultaviolet Photography in Colour

I don't know off hand all the bits and bobs but I do recall a stern warning about skin/eye damage from certain uv sources depending on wavelength so worth making sure on that

Re: Infrared and Ultraviolet clip on flash emitters.

I came across a web site
"universe kogaku America inc." They have lens and adapters for c mounts and t mounts for universal mounting including eos canon. They are quartz lenses that are down around the price of normal and higher class lenses. My question is would the T- mount give poor performance ? I have a T- mount for a telescope and it seems like it would work. These people talk like they are expanding into digital slr photography.

Re: Infrared and Ultraviolet clip on flash emitters.

That reflector from Quantum looks interesting - but the price of the flash

I am thinking of getting some flash or maybe LEDs for some winter play with my IR camera.

I not that Silver mentions the flash makes no difference - maybe I will try that sometime. If the LEDs are no good ?? Then maybe the diffuser could be "Adapted" to fit a speedlite via some DIY

When I had the bank of UV lights on the camera flash could be seen in the picture, when I turned the UV off I couldn't see the camera flash. Some of the light must enhance the UV from the flash. Doesn't make sence to me but that's what it looked like. I really need to spend some quality time with my little camera

I have no idea how much UV spectrum you get from a standard flash but I do know there's a fair few who use standard speedlights to add light to IR pics so that for sure works (not personally tried it but have seen enough pics to know it works)

Re: Infrared and Ultraviolet clip on flash emitters.

Back to my very first question. The clip on emitters were a kind of filtered filter shaped cup like and fit down over a speed lite emitting UV and IR. I still have not been able to find them . I think maybe they were on the Klaus site invisible world. There is so much information there it could have been a 3rd party link.
I know the speed lite had an effect as I was shooting in the surface of my ovation and it reflected back as a burned out spot. The pictures I posted in "photos for fun", I can't remember if I had the flash on, I would guess I didn't.

I think it's time for more photos and less talk,,,
