Hello all,
Is it possible to make tungsten light look "white"? I've taken many photographs, and although tungsten is easy to color correct - I haven't been able to make it "white". Is it possible for night scenes? Day scenes? Is there a filter for this effect? CTW (color temperature white)?

Oh, one more question, does anyone recall how Saving Private Ryan had the "strobe" effect when the soldiers were in the middle of the action. If so, please advise on that topic also.

Thanks.

C.L.

Tungsten should look neutral on film balanced for it (3200K). Household lamps are slightly warmer than 3200K (more like 2800K) but that can be corrected in post if needed.

"Saving Private Ryan" used a 45-degree shutter angle to get jerkier, strobing motion. At 24 fps with a normal 180 degree shutter, the exposure time is 1/48th of a second per frame. At 90 degrees, it is 1/96th and at 45 degrees, it is 1/192nd.

Hello,

Adding a little blue gel can "trick" the brain into thinking the light is whiter, but only if there is a normal or warmer light in the shot. Decide which side you want normal and which side "whiter". You will also need to take notes on which light is which so you'll get the proper effect in color timing.

The use of normal light on the front of the face and a blue-gelled back light rimming the opposite side is a common trick for night, exterior scenes. Especially, night, street scenes.

Hope that's useful.
