Non-UV flash

1 year 9 months ago #691599 by grafxman
I often take photos inside museums. Some do not allow flash. They claim the UV destroys their paintings. I typically use a video light in those cases. However nothing beats a flash for removing reflections from light bulbs, windows, etc. So now I am wondering if there is anyway to block the UV that the flash emits? I would need written proof to carry with me so I could show it to the museum folks if such a thing exists. My Canon flash has built-in filters but none of claim to block UV. Any ideas?

Video lights may affect paintings and yes, UV is deadly stuff
for their paintings. But speed lights? Well, they emit no UV.

Light is free… capturing it is not!

Thanks for your quick reply. Can you provide documentation that camera flash units do not emit UV light? I will need to print something out to carry with me as proof that there will be no UV light emitted by the flash unit.

That should be easy to google… isn't it?

Yeah, that's what I thought. However, anytime UV and Flash are used as search terms the results typically talk about using the flash for UV photography. Everyone wants to do black light photography. Flash specs rarely mention anything about UV output or lack there of.

The fact that flashes must be tweaked to emit UV
should put you on the right track. Good night sir.
