Color Temp with Photogenic 1250


Does anyone know the specific color temp of a Photogenic 1250 strobe light? Someone suggested that strobes should say their color temp output in their material, but I can't find any info about this. I still struggle with WB in the studio, having tried auto, flash and daylight. I'm wondering if I set a specific number if that would help. Thanks!

  Tara,
Most studio strobes will center around 5,500K or daylight (+-) 200K.
Deviating downward will cause a slight blue shift, upwards, a slight shift to the red.
Neither excursion will give you poor color balance.

  Hi Tara,
Just wanted to mention that shooting in Raw will allow you to easily change/correct color balance after the shot with Photoshop ACR or other RAW editing software.

Marc D. Bell   Hi Tara,
I'm sure you're metering your lights, correct? When shooting with strobes (my preferrence is Paul C. Buff's: White Lightning) you should adjust your color temperature ("K" Kelvin) and take shots of something with several colors in it. Then shoot a couple of shots with all Kelvin temp. settings and find which setting gives you the results you desire. I would also keep a list of images you shot and which K setting temp. you used to capture the image. It's much better to learn from experience and not simply go into a photo altering program to fix your images. I'm sure you will figure it out. Good luck!

Tara R. Swartzendruber   OK, I hesitate to respond because I think some of you might just roll your eyes at me.... BUT, here goes.
I did ask photogenic. The color temp of my main and fill light are 5800, the temp of my backlights are 5200 (also photogenic). I have the most trouble with light haired people (i.e. my light-brown haired baby shows up more blond). I have tried many ways of adjusting the lights and camera (for exposure), and the way that I generally use them seems to work the best...other settings make my white background more blue or grey. I want it to be white. So I've focused on white balance to see if I can correct things there. But 5800K gives a slight orange cast to the white background (although it exposes the hair correctly), which I can correct somewhat using "levels," but I'd like to get things more correct. I know some of you will say to use a light-meter, but my style of photography just doesn't seem to allow this very well. I take pix of babies/little kids who don't just stay in one place so I can meter them, they move all around and I, too constantly move. I know what settings (exposure)work good when I am close to their face, and when I am futher back, etc.... the biggest problem is that my light-haired kids get "lighter" and sometimes men's/teen guy's faces show up more red than they should (esp. on black background), so I am trying to adjust white balance. I have tried a number of different settings, but nothing seems to work quite right. Anyone who has helpful advice for me on what I am doing right or wrong, I would welcome...

Ok, in my 2nd call to photogenic I learned that my kit was all corrected to 5400K. SO, since that is not a preset K option, I set my WB to flash which the D80 says is set to 5400K.
This is the option I get....still looks a bit grey/redish. If I change my exposure to get rid of the grey/red, the subject looks washed out. Any ideas?
