1. Understanding the Basics
* What are Colored Gels? Transparent sheets of colored plastic that fit over your light source. They alter the color of the light emitted.
* Types of Gels:
* Color Correction (CTB/CTO): Change the color temperature of your light. CTB (Color Temperature Blue) cools down the light, while CTO (Color Temperature Orange) warms it up. These are often used to balance different light sources.
* Creative Gels: A vast array of colors for adding creative effects.
* Neutral Density (ND) Gels: Reduce the amount of light without affecting the color. Useful for balancing bright light sources.
* Light Sources: You can use gels with speedlights (flashes), strobes, or even continuous lights. Make sure the light source doesn't get too hot, as some gels can melt or burn with prolonged exposure to high heat. LEDs are a good, safer option.
* Gelling Tools: You'll need a way to attach the gel to your light source. Common options include:
* Gel Holders: Clip or magnetic attachments specifically designed for holding gels.
* Gaffer's Tape: Heat-resistant tape (essential for holding gels in place, especially on strobes).
* Clothespins: Can work in a pinch, but less reliable than dedicated holders.
2. Planning Your Shot
* Concept & Mood: Decide what kind of mood you want to create. Think about the colors that evoke that mood (e.g., red for passion, blue for melancholy, green for mystery).
* Color Harmony: Consider color theory. Will you use complementary colors (opposites on the color wheel, like blue and orange) for contrast, or analogous colors (next to each other, like blue, blue-green, and green) for a more harmonious look?
* Subject & Wardrobe: Choose a subject and wardrobe that complement your chosen color palette. A red dress will look different under a red gel than a blue one. Consider skin tones. Some colors can make certain skin tones look sallow or unnatural.
* Lighting Setup: Plan your lighting setup. Will you use one light with a gel, multiple lights with different gels, or a combination of gelled and ungelled lights?
3. Lighting Setups & Techniques
Here are some popular and effective colored gel portrait setups:
* Single Light with Gel: The simplest. Place your light with a gel to one side of your subject. Experiment with the angle and distance to control the intensity and shadow patterns.
* Two Lights, Different Gels:
* Complementary Colors: Place one light with a warm gel (e.g., orange, yellow) on one side and another light with a cool gel (e.g., blue, purple) on the other. This creates a dynamic, contrasting look.
* Color Gradient: Use two lights with similar, but slightly different colors (e.g., light blue and dark blue) to create a subtle gradient effect.
* Rim Lighting with Gels: Place one or two lights behind the subject, pointing towards their shoulders and head, with colored gels to create a colored outline. This works well to separate the subject from a dark background.
* Background Wash: Place a light with a gel shining directly onto the background. This can add depth and visual interest to a plain background. Experiment with the distance of the light to the background for different levels of saturation.
* Gelled Key Light, Ungelled Fill Light: Use a light with a gel as your main (key) light, and an ungelled light to fill in the shadows. This gives a more balanced look, with the color being less overwhelming.
* Using a Gobo with Colored Gel: A gobo is a stencil that creates patterns of light and shadow. Combine a gobo with a colored gel to project colored patterns onto your subject or background. This is more advanced, but can produce very interesting effects.
* Negative Space: Sometimes, the absence of color is just as powerful as the presence of it. Experiment with letting the colored light fall only partially on your subject, leaving areas in shadow or with natural skin tones.
4. Gear & Settings
* Camera Settings:
* Manual Mode: You'll need to control your aperture, shutter speed, and ISO to get the correct exposure.
* White Balance: Experiment with your white balance. Auto white balance can sometimes correct the colors too much. Try setting it to "Tungsten" or "Fluorescent" to see how it affects the final image. Shooting in RAW gives you more flexibility in post-processing.
* Metering: Pay close attention to your meter. Gels can throw off your camera's metering system. Take test shots and adjust your settings accordingly. Underexposing slightly can often enhance the color.
* Power Settings on Flashes/Strobes: Start with low power settings and gradually increase them as needed. This helps prevent overexposure and allows you to fine-tune the intensity of the color. Consistency is key, so if you find a power setting that works well, try to stick with it.
5. Post-Processing
* RAW Editing: If you shoot in RAW, you'll have more control over color correction, white balance, and exposure adjustments in post-processing.
* Color Grading: You can further refine the colors and mood of your images in post-processing. Experiment with color curves, selective color adjustments, and split toning.
* Contrast & Clarity: Adjusting contrast and clarity can help make the colors pop and enhance the overall visual impact.
6. Tips & Tricks
* Start Simple: Don't overwhelm yourself with too many colors at once. Begin with one or two gels and gradually add more as you become more comfortable.
* Test Shots are Crucial: Take plenty of test shots to see how the colors are interacting with your subject and the environment. Adjust your settings and lighting as needed.
* Distance Matters: The distance between the light source and your subject affects the intensity of the color. The closer the light, the more saturated the color will be.
* Diffusion: Using a diffuser (softbox, umbrella) with a gel will soften the light and create a more gradual color transition.
* Experiment! Don't be afraid to try new things and break the rules. The best way to learn is to experiment and see what works best for you.
* Use a Colorimeter/Spectrometer (Optional): For serious color accuracy, a colorimeter can measure the color output of your lights with gels and help you dial in precise adjustments in post-processing.
* Safety First: Be mindful of heat. Avoid placing gels too close to hot light sources and monitor them regularly. Use heat-resistant tape.
Example Color Combinations and Their Effects:
* Red & Blue: Dramatic, contrasting, can evoke a sense of conflict or passion.
* Orange & Teal: Popular combination. Warm skin tones under orange are balanced by the cool teal in the background or as a rim light.
* Pink & Purple: Dreamy, ethereal, feminine.
* Green & Yellow: Unusual, can create a sense of unease or mystery. Think alien or sci-fi.
* Monochromatic (Different Shades of One Color): Sophisticated, unified.
By understanding the principles of colored gel photography and experimenting with different setups, you can create truly unique and creative portraits that stand out from the crowd. Good luck!
