Ok, there has to be some other cheap SOB out there who has come up with something like this, or tried to.
I have an SB50DX. It came with an infrared filter that allows the flash to be used as a command flash unit for wireless operation with other Nikon flash units. My thought is that since infrared is just an invisible component of light I should be able to use the flash with filter to fire my studio lights. Anyone else tried this and did it work. I was also thinking along the lines of coming up with an IR sensor to generate voltage to fire the flash.
I would try it myself except I cant find the filter just now and dont want to order a replacement if it wont work for me.
Thanks!

They make cheap infrared flash triggers that mount in your hot shoe. Someone rented my studio the other night and had one -- worked great triggering my lights!

I often use a standard sb28, or sb80 to fire my studio lights.

You set your main lights up and mount the sb28 on the camera. I have the camera on manual mode already, and I just put the flash on manual and set it to 1/32 or 1/16 manual power and turn the pivot head to bounce it off the ceiling.

It's enough light to fire the studio lights, but not enough to to register in the photo.

Or if you have a main light off to one side, you can aim the pivot head to throw light in the direction of the main light if you don't have a ceiling to bounce off of.

Sometimes when I have a light facing a direction where the "slave eye" doesn't want to see the trigger light coming from the camera, I tape a 3x5 card on the side of the flash and bend it to pick up the "trigger flash" and bounce it onto the slave eye.

Works every time.

I have a set of pocket wizards now, but that's how I did it for years.

Yes...it should work. [img]/ubbthreads/images/graemlins/smile.gif[/img]

I have a Infrared Flash trigger, and it is just a low powered flash with a plastic IR filter in front of it.

Being one really cheap SOB, I can do Jason407 one better. You can use a piece of developed, unexposed slide film as an IR filter. It really works. The film transmits in the IR, but not much at all in the visible. I've used such in front of a small, nonautomatic shoe-mount flash to trigger WL 5000 monolights. Since most solid state light sensors are sensitive in the near IR, most slaves will be triggered by this light.

If you've got a box of slides around, chances are you have an unexposed "end" stuck in there, available to try.

I've been using one of these for about 3 years. Used it on my old Nikon 5000 and now on my 10D. Have never had a problem with it and yes the trigger voltage is safe. Only 5 volts.

I also use the 50DX in IR mode to fire studio and have the Wein IR slave on the lights. It says up to 3000 feet range. It is small and very reliable.
