I ask because Kodak has just introduced an interesting product, a deep red
LED safelight designed for use with dental X-ray film: http://www.kodak.com/global/plugins/...ntal/D5-28.pdf This might be ideal for illuminating observatories too. Does anybody know how much it costs? I understand that LED safelights are made for ordinary darkroom work too, but my understanding (possibly mistaken) is that they're orange. Ah, to get back into the darkroom! Too busy! |

I believe Marty, if he's not being the Sun,
is a dentist, so perhaps he can chime in with this sources. Esmail Well, I'm not really a REAL dentist... I have an office I go to and fix people's teeth, but I wear jeans and boots, and I haven't had one of those "doctor suits" since I got out of dental school. (Worst professional image on the planet.) My webbybox doesn't seem to work on that hyperlink, but I'll see what I can come up with. Dental Xray film is pretty much just a fast orthochromatic film so that it takes a low dose of radiation to expose it, and it can be opened under a red light, like photographic printing paper. I used to use sheets of dental film in old glass plate cameras just to play with 'em. I'd think if there's a buck to be made, LED safelights should be available to regular photographers with darkrooms. ? . Marty |

Orange LED safelights have been around for a while. The red one caught my eye because of its usefulness in observatories. |
