Hello

What will be the ideal option for hair/back light along with Diva-400 as key light.
I added Arri 650 then noticed that different color temperature will cause WB problem , I have the Sony EX1 and Canon XHA1.
My aim is to shoot one person interview mostly will be indoor.

Thanks

My habit has always been to use the same "type" of light for key-fill-backlight set. In this case a Diva 200 would be appropriate.

Solution #1: John's post above: use a Diva 200 for a back light if you are using a 400 for a key.

Solution #2: are you tubing the Diva with tungsten bulbs? If they are daylight, there will be a huge difference. The cheapest way to correct that problem would be to gel the 650 (which is probably way too hot and needs to be scrimmed way down) with 1/2 CTB. The back light will then be pleasantly warm. However, if your interviewee is silver haired, add another 1/4 to 1/2 CTB to cool the light even more.

Whether you tube with tungsten or daylight, Divas tend to have a green spike. A 1/8 or 1/4 minus-green gel (magenta) should cure that. Osram tubes seem to run to a more true color.

There was a series of posts on CML about how the EX1 seems to react to Divas differently from true tungsten lights. I found no convincing posts. In any case, test with some color-correcting gels to even things out. A little trial and error and you should be good to go.

Remember, color variations run along two axes: the blue-orange axis (CTB/CT0) and the Green-Magenta axis (Plus-Green/Minus-Green.)

How about getting the Arri 150 as kick/back light and use 3200 tungsten bulbs with the Diva 400 , will this work ?
