HI all, i'm new to the forum. I have come here as no one i know seems to know the answer to my problem. I am using in visible u.v ink within drawings. You can see this ink when i light it up with led's. I am trying to work out how to photograph this if anyone can help please? I assume it will be an exposure or filter fix? I intend on buying a camera that can do this, but wasn't sure what was required.

The images I have been getting from, a camera phone and a digi cam (kool pix) have all been really over exposed.

Thanks

Darren
 
Try dialling in some deliberate underexposure. You can do this on most cameras by pressing the button marked +/- and the control wheel - have a look at your camera's manual to find out how to do it on your particular model.
 
Further to Nods reply.

As you mention using the camera phone or Nikon Coolpix,...........so daft question are you using the flash?
 
Are you using exclusively UVinks ? If so lookup Black light photography. However if using both uv and standard inks then I am wondering if as the subject is static you will need to do two exposures. One under black light and the second under ambient light, then combine the two images???
 
Further thought... Maybe try Manual mode (if available on your camera). Start at the camera's suggested settings (which may well be overexposed) then keep the shutter speed the same and try smaller apertures (larger numbers). If you get to the biggest number and the shots are still overexposed, increase the shutter speed. Eventually you should get something useable. Make a note of the settings that give the best results so you'll know what to use next time!
 
It's not really a camera specific feature, but you need something that you can mount on a tripod and that gives you total control of the exposure.
 
You say quote " You can see this ink when i light it up with led's" unquote


"Then why not just use led lights to show the ink up and then take a photo of the image with the led light on it?


One these should do the trick of lighting it up being led lights

You just need a black light (you can buy black light bulbs to swap out on.a standard desk lamp). As your subject is static you shouldn't need anything too powerful (or expensive).
