Using gels and Tungsten white balance

Now that I have my radio triggers and can trigger 2 flashes off camera, it is time to actually put them to use. Previously, I have been too lazy to take any pictures that really stretched my knowledge, but after viewing

where a guy takes a picture every day for 365 days each one better than anything I have ever done, it was time to start learning again.

This project was done with a tungsten white balance, giving the ambient light a blue hue. I then used a second strobe with a full CTO to add the orange color, and placed that inside my largest gridspot. The retricted orange light in theory should exactly counteract the blue from the tungsten white balance, giving a regular colored area where it strikes. For the sake of reference, all the images were shot in a white hallway.

The first two images are just the blue tinted pictures from the white lights turned blue through the tungsten white balance. It is an interesting note, but when the amount of light is too great, it actually becomes white, instead of colored. If you want to change the color of a wall, you are actually better off using a lower power as a higher power will dilute the color with too much light.





The second two images show the effects of the CTO, where the model has regained his normal skin color.
