Using Colored Gels for Unique and Creative Portraits
Colored gels are a powerful and relatively inexpensive tool to add visual interest, mood, and drama to your portraits. They allow you to transform a simple image into something truly unique and creative. Here's a comprehensive guide to using colored gels effectively:
1. Understanding the Basics:
* What are Gels? They're transparent sheets of colored plastic that you place in front of your lights to change the color of the light source.
* Types of Gels:
* Color Correction Gels (CTO/CTB): These are used to balance the color temperature of your lights to match the ambient light. We won't focus on these here, but they're good to know.
* Creative Color Gels: These come in a wide range of colors and are used for artistic effect.
* Diffusion Gels: These soften the light, making it more flattering. (Often used with colored gels).
* Choosing Gels: Start with a variety pack to experiment. Popular colors include:
* Blue: Cool, calming, futuristic, or dramatic.
* Red: Passionate, intense, angry, or romantic.
* Green: Mysterious, eerie, natural, or toxic.
* Yellow: Warm, happy, energetic, or vintage.
* Pink/Magenta: Playful, feminine, energetic, or dreamy.
* Orange: Warm, inviting, vintage, or sunset-like.
* Gel Holders/Grids: These attach to your lights and hold the gels in place. Grids can help control the spread of light, creating more focused pools of color.
2. Equipment Needed:
* Lights: Strobes (studio flashes) are ideal, but speedlights (portable flashes) work well too. Constant lights can also be used, but they generate more heat. *Important: Constant lights can melt gels, especially if they are hot. Use heat-resistant gels or keep the light farther away.*
* Light Stands: To position your lights.
* Gel Holders: Designed to attach to your specific light. Sometimes simple tape and clothespins will work in a pinch!
* Colored Gels: A variety pack is a great starting point.
* Camera with Manual Mode: Essential for controlling your exposure.
* Light Meter (Optional): Helpful for accurately measuring light output, especially when using multiple lights.
* Tripod (Recommended): Especially if you are working with slower shutter speeds.
3. Setting Up Your Lights:
* Single Light Setup:
* The simplest way to start.
* Place your light with the gel to one side of the subject.
* Adjust the light's position and power to achieve the desired effect.
* A reflector on the opposite side can help fill in shadows.
* Two Light Setup (Key and Fill):
* One light with a gel as the *key light* (main light) and another light (with or without a gel) as the *fill light* to soften shadows.
* Consider using contrasting colors for a more dramatic look (e.g., blue key, orange fill).
* Rim Lighting (Backlighting):
* Place a light with a gel behind the subject to create a colored outline. This works well for separating the subject from the background.
* Background Lighting:
* Shine a light with a gel directly onto the background. A seamless paper or muslin backdrop works well.
* Multiple Lights (Complex Setups):
* Experiment with using multiple lights, each with a different colored gel, to create layered and complex effects.
4. Camera Settings:
* Manual Mode (M): Gives you full control over your exposure.
* ISO: Keep it as low as possible (usually ISO 100) to minimize noise.
* Aperture (f-stop): Adjust the aperture for the desired depth of field. Wider apertures (e.g., f/2.8, f/4) create shallow depth of field and blurry backgrounds. Smaller apertures (e.g., f/8, f/11) create greater depth of field and sharper backgrounds.
* Shutter Speed: Set your shutter speed to sync with your flash (usually around 1/200th of a second for most cameras). If you're using constant lights, adjust the shutter speed for proper exposure.
* White Balance: This is crucial!
* Custom White Balance: The most accurate method. Use a grey card under your lighting conditions and set your camera's white balance to match.
* Tungsten/Incandescent: Can work well if you're using mostly warm-toned gels.
* Flash: A good starting point.
* Adjust in Post-Processing: You can adjust the white balance in post-processing, but it's best to get it as close as possible in-camera.
* Metering: Use your camera's built-in light meter to get a starting point for your exposure. Take test shots and adjust accordingly.
5. Creative Techniques & Tips:
* Complementary Colors: Using complementary colors (opposite each other on the color wheel, like blue and orange, or red and green) can create a visually striking and dynamic effect.
* Monochromatic: Using different shades and intensities of the same color can create a subtle and sophisticated look.
* Color Theory: Learn basic color theory to understand how different colors interact and evoke different emotions.
* Less is More: Start with a subtle approach and gradually increase the intensity of the colors. Too much color can be overwhelming.
* Diffusion: Use diffusion material (like tracing paper or a softbox) to soften the light and create a more pleasing effect.
* Experiment with Angles: Vary the angles of your lights to create different shadows and highlights.
* Combine Gels: You can layer gels to create new colors and effects.
* Black and White Conversion: Try converting your colored gel photos to black and white. The different colors will translate into different shades of gray, creating a unique look.
* Post-Processing: Use post-processing software (like Photoshop or Lightroom) to fine-tune the colors, contrast, and sharpness of your images.
* Consider the Mood: Think about the mood you want to create and choose colors that support that mood.
* Subject's Skin Tone: Be mindful of how the colors will affect the subject's skin tone. Certain colors can make skin look unnatural.
* Hair and Makeup: Coordinate the hair and makeup with the colors you are using.
* Background Choice: Choose a background that complements the colors of your gels. A neutral background can work well, or you can use a colored background that matches or contrasts with your gels.
* Direct vs. Bounced Light: Experiment with bouncing your colored light off a wall or reflector for a softer, more diffused look.
6. Examples & Inspiration:
* Split Lighting: One side of the face lit with one color gel, the other with another (or left in natural light).
* Cyberpunk: Use blue and pink/magenta gels for a futuristic, neon look.
* Film Noir: Use dark blue or green gels for a dramatic and mysterious feel.
* Abstract Portraits: Focus on the colors and shapes created by the gels, rather than the subject's face.
* Silhouette Portraits: Light the background with a colored gel, creating a silhouette of the subject.
7. Practice and Experimentation:
The key to mastering colored gel photography is practice and experimentation. Don't be afraid to try different combinations of colors, lighting setups, and camera settings. Take lots of test shots and learn from your mistakes. Have fun and let your creativity flow!
By following these guidelines, you can use colored gels to create truly unique and creative portraits that will stand out from the crowd. Good luck!
