There is a progression that takes place in the journey that is our lighting knowledge. At first it is learning the ways of ambient light (read: I don’t want to buy a flash). As our career progresses we decide to buy our first flash and throw that sucker straight on the camera, only to question why the shadows on faces are gone… along with the artistic merit. Soon after that we discover a site like Strobist and point the flash at the ceiling and realize our first “Eureka” moment as a photographer. From there we buy our first off camera strobes and it is all downhill…
Off camera strobes are something that I think should be classified as a different genre in the medium of photography. I say this because they are a part of the knowledge base that some photographers will never need to understand to be successful (like photo-journalists and landscape photographers). However, for advertising photographers like myself, they are crucial to my workflow and often make or break an image. We often talk about how bringing lights to an image creates mood, but rarely discuss how it can destroy it, but I digress.
At a certain point in your career, you will reach a level of knowledge that must expand outside of its F-Stop constraints and into an on set Kelvin world that is not just a derivative of white balance. I am of course talking about gelling the lights. For the standard still photographer, this is probably a skill set that will not be critical to his or her success, as it might slow down time on set and impede efficiency. However, if you ever want to work in Hollywood (or at least Los Angeles) you should be driving to the store to pick up a gel set before finishing this blog.
Now the reason I mention Hollywood is that movie and set lighting are more of a product of the color of a light, rather than its brightness. How often do you watch a film or tv show and think, “is every light that green in a dark alley?” What you are taking in is actually quite special, for it is a color palette painting the on-screen action. If you want a nice example of this, watch Man in the High Castle on Amazon Prime. In it you will see light coming through windows that appear like they lit with an neon sign… quite beautiful really.
But you are probably wondering, “how do I incorporate this into my photography?” It is really quite simple, practice (after buying the gels at the store which you are currently driving to). There are multiple ways and theories behind approaching split lighting with color. One would be to perfect the hell out of your orange and blues (natural balance), while the other would be to master the effects set (your greens, yellows, reds etc). Going with the natural gels route, you will find your lightings beginning to compliment the skin of your model. As an added bonus, you will also find that you specular highlights will also gain more depth and form will have more dimension.
The second approach, lighting with the non-natural set (effects colors) will give the image a unique artistic quality not found in the natural tones. Here is where it gets a little dangerous, because (as is the case with adding lights) using the non-natural color set can destroy an image, especially a portrait. The reason for this is that we need to have context and balance for the eye of the viewer to not have aversion. Imagine yourself standing in a room with a single green lightbulb. While the light from it is probably fun, the reality doesn’t strike you as normal, because light in our minds is white.
As with all photography tips, the answer of how to do this properly is the hard part, you need to learn both. In this way you will be able to tell the viewer’s eye where the balance is with the knowledge built from the natural color gels, as well as create a narrative with the color set. Sure there are rules to be bent (or broken) will bringing color into lighting, but the fundamentals must be your base upon which you build.
Now for a couple tips to help you along the way:
- Learn lighting first with no less than three heads. This way you will understand the purpose of a key, fill and kicker before trying to modify them.
- When practicing, underexpose so you can get an idea of the true color tone before cranking the light up and dialing out the saturation with watts.
- This is the biggie…. KNOW YOUR CAMERA’S SENSOR!!! Not all cameras process color the same way. Some put heavier reception on the in green or red channels, and knowing what tones will have more depth will compliment your efforts.
