Studio "hot lights" + film type


I'm going to do some Christmas portrait work soon. I will use studio "hot lights" and umbrellas with off the camera flash for fill. Can I get by with daylight film without suffering color shift problems. Or should I use tungsten film. Would daylight film with a tungsten filter work?

  It depends on what "hot lights" you're using. There are some that are color corrected for daylight film. I suspect yours are not. If not you will get a color cast. Tungsten film is fine or a blue filter. There are a couple of filters for this. One is stronger than the other depending on what the actual color temp of your lights is.

  I am wondering why you are going to use flash for fill while using Tungsten lights. You will end up with a mixed light situation, which if you shoot for the the Tungsten light as your main light by either using tungsten film or blue filtration may give you a slight blue cast in your somewhere in your photo. I do not understand why you just do not use tungsten for both main and fill light. It is probably better to go with one type of light source to keep it simple, otherwise if you still want to use mixed lighting, you should experiment with this effect before your actual shoot. Additionally, remember that depending on the power of your hot lights and speed of film you might be working with a pretty slow shutter speed. I recall a shoot which required 1/60 at F5.6 on 400 speed tungsten film. This wasn't too bad, but there were some exposures that had motion blur and of course the inherent lost of depth of field. Tungsten, depending on the power, in general does require less motion from the subject & camera and/or faster film than flash to avoid motion blur. Consider this when using filters with daylight film because then your losing additional stops due to the filter factor.

Happy Shooting!
