I'm considering making a homemade hotlight Frankenstein monster, and was wondering something.

It'll be a 7 bulb (200-250 watt each) incandescent, one bulb in center, and six bulbs in a circle around it, bulbs mounted through/on a board, all THAT mounted on homemade tripod/stand thingy, with the light going through some sort of diffuser.

More for a fun cheapo project than really attempting to re-invent the lighting wheel. And heck, if it works, it works.

Question: can my D70 accurately compensate for the color temperature of standard cheap 2750K color temp incandescent bulbs through it's white balance functions, or would the extra cost for color balanced full spectrum incandescents be worth it to avoid color balance/temp issues?

Three things. First, I'm not a D70 owner but I'm sure that you can get pretty close on the white balance. It will probably be a bit warm -- but if this is a beauty kind of light, then that's a GOOD thing.
Second, if you shoot RAW you can adjust the white balance outside the camera. That's a good alternative if you're doing studio work. I hope you're not taking this monstrosity on location!
Third, I have been experimenting with the Reveal and similar bulbs. It doesn't cost that much more -- and my opinion is that it would be worth the $15 - $20 or so to go with the daylight bulbs.

I guess one other thought -- I'm always the safety monitor around here -- that thing will not only be heavy but also get pretty HOT. PLEASE be careful about whatever diffuser you use that it doesn't catch fire. Remember to bore a few holes in the backboard for heat relief. And the heat may cut down on bulb life as well.

"Daylight balanced" fluoressant tubes -- a little warm, but I like it!

Bob,

Thanks!

I figured the camera could get a close white balance, esp. w/raw later, good to hear it from others. I'll look into Reveal bulbs, thanks! [img]/ubbthreads/images/graemlins/smile.gif[/img]

Oh yes, I'll be very careful not to set fires. [img]/ubbthreads/images/graemlins/tongue.gif[/img]

Studio only of course... [img]/ubbthreads/images/graemlins/grin.gif[/img]

Hi Im a d70 owner and i would also say just do it raw then in nikon capture 4.1 yuo have total ajustment so you can set it how you like.

Im interested in what you are trying to make, is it just a defuesed light source or like in that picture above are you trying to make a ring flash type of effect.

I would like to build a light source that can make this effect and was thinking of using 2ft florecents in a square and shooting through the centre of it, but was unsure if they had the power to expose in my pictures if i used my flashes with them.

Anybody with any experience in this as im a bit of a cheap scate and dont want to spend out on a power pack and a ring flash as im using monoblocks at the mo.

What about just doing a custom white balance with the camera ? I shoot with a D100 so I am not sure if your D70 has that option or not. It should have it.

[/ QUOTE ]I have Thom Hogan's D70 ebook. According to it, the incandescent setting with a +2 compensation is 2800K and with a +3 compensation is 2700K. That should get you in the ballpark.
