Re: want to mimic sunlight w/o heat for indoor pho
Good job of explaining, lenny45!
The so called daylight flourescent bulbs, and there are several of them at different spreads of the spectrum, are great for plants and the really expensive ones are for reptiles.
Lenny also nailed the answer earlier when he recommended tungsten film/bulbs or flash/digital.
Most camera stores carry a dark blue bulb meant to simulate daylight on daylight film but usually (IMHO) leave a somewhat noticable warm cast to the photos. If you have a really good operator at your photo lab, they can correct for most of it. I have yet to see a one hour photo shop or Wal Mart style send away lab take the trouble to do so. The best choice in send away developing is Kodak. Select the deluxe developing (read most expensive) and they will color correct as much as is possible.
There are also some very inexpensive flash units on eBay that work reasonably well if you have a light meter to measure exposure. If it is in your budget, get a unit that has a slave feature so it will fire when the camera flash fires, thereby providing fill to balance the lighting and make a more pleasing photograph.
