Using Colored Gels to Create Unique and Creative Portraits
Colored gels are a fantastic, inexpensive way to inject personality, mood, and visual interest into your portraits. They can transform a simple shot into something truly unique and creative. Here's a guide on how to effectively use them:
1. Understanding the Basics of Colored Gels:
* What are they? Transparent sheets of colored plastic (usually acetate or polycarbonate) placed in front of a light source.
* What do they do? Filter the light, changing its color.
* Why use them? To add mood, create visual effects, enhance skin tones (surprisingly!), isolate subjects, or create dramatic and surreal looks.
* Types of Gels:
* Color Correction Gels (CTO/CTB): Orange (CTO - Color Temperature Orange) converts daylight to tungsten color temperature. Blue (CTB - Color Temperature Blue) converts tungsten to daylight. Useful for balancing lighting when mixing different light sources.
* Color Effect Gels: A vast range of colors (red, blue, green, yellow, magenta, etc.) for creative and artistic effects.
* Neutral Density (ND) Gels: Reduce light intensity without changing color. Useful for balancing light ratios or creating motion blur.
2. Gear You'll Need:
* Colored Gels: Start with a basic kit containing a variety of colors (red, blue, green, yellow). Rosco and Lee Filters are popular brands.
* Light Source(s):
* Speedlights (Flashes): Versatile and portable, ideal for single or multiple light setups.
* Studio Strobes: More powerful and typically offer more precise control over light output.
* Continuous Lights (LEDs): Offer a "what you see is what you get" experience, but may not be as powerful as strobes or speedlights. Choose LEDs with good CRI (Color Rendering Index) for accurate color representation.
* Gel Holders: Essential for attaching gels to your lights. These can be simple clip-on holders or more robust magnetic systems.
* Light Stands: To position your lights.
* Modifiers (Optional):
* Softboxes: Create soft, diffused light.
* Umbrellas: Another option for soft light, often more portable than softboxes.
* Snoots: Concentrate light into a narrow beam.
* Reflectors: Bounce light to fill shadows and add highlights.
* Trigger (For off-camera flash): If you're using off-camera flash, you'll need a wireless trigger to fire your speedlights or strobes remotely.
3. Basic Techniques and Setups:
* Single Light Setup:
* Background Gel: Place a gelled light behind your subject to color the background. Experiment with different colors to see how they affect the overall mood.
* Key Light Gel: Gel your main light (key light) to bathe your subject in color. Subtle colors like light pink or peach can warm up skin tones, while bolder colors create dramatic effects.
* Two-Light Setup (One Gelled):
* Key Light + Rim Light: Use a key light (un-gelled or with a subtle gel) to illuminate the face and add a gelled rim light (placed behind the subject, slightly to the side) to create a colored outline. This separates the subject from the background and adds dimension.
* Key Light + Fill Light: Use a gelled key light for the main illumination and an un-gelled fill light (using a reflector or a second light) to soften shadows.
* Two-Light Setup (Both Gelled):
* Complementary Colors: Use two gels with complementary colors (e.g., blue and orange) to create a dynamic and visually appealing contrast.
* Split Lighting: Gel one light with one color and the other with another, and aim them from opposite sides of the subject to create distinct colored halves on the face.
* Three-Light Setup: Combines the above techniques for more complex and controlled lighting. You could have a gelled key light, a gelled rim light, and a fill light.
4. Creative Ideas and Tips:
* Match the Mood: Consider the emotion you want to convey. Blue and purple can evoke sadness or mystery, while red and orange suggest passion and energy.
* Experiment with Color Combinations: Don't be afraid to try unexpected color pairings. Analogous colors (colors next to each other on the color wheel) tend to create harmonious looks, while complementary colors create strong contrast.
* Subtle vs. Bold: You don't always need to blast your subject with intense color. A subtle gel can add a touch of warmth or cool tone without being overwhelming.
* Gel Strength: Gels have different strengths. A full CTO gel will significantly change the color temperature, while a half CTO will have a less drastic effect.
* Diffusion: Use diffusion materials (like tracing paper or diffusion gel) with your gelled lights to soften the light and create a more even color distribution.
* Backgrounds: Experiment with different backgrounds to see how they interact with the colored light. A white or neutral background will allow the colors to stand out, while a colored background can create a more layered and complex look.
* Skin Tones: Be mindful of how gels affect skin tones. Some colors can make skin look unnatural or unflattering. Consider using color correction gels to balance the light before adding creative colors.
* Model's Clothing: Choose clothing that complements or contrasts with the gels you're using. Neutral clothing will allow the colored light to be the focus, while brightly colored clothing can create a more vibrant and dynamic look.
* Eye Lights: Make sure your subject has catchlights in their eyes. This adds life and sparkle to the portrait. You can achieve this by strategically placing your lights or using a reflector.
* Color Theory: Understanding basic color theory principles (e.g., complementary colors, analogous colors, color harmony) can help you create more effective and visually appealing color combinations.
* Post-Processing: You can further refine your colors and adjust the overall look of your images in post-processing software like Photoshop or Lightroom. However, aim to get the lighting as close as possible in-camera.
* Practice, Practice, Practice: The best way to learn how to use colored gels effectively is to experiment and practice. Try different setups, color combinations, and light placements to see what works best for you.
5. Examples of Creative Concepts:
* Sci-Fi Portraits: Use blue and purple gels to create a futuristic or otherworldly look.
* Dramatic Portraits: Use red and black gels to create a high-contrast, dramatic portrait.
* Fantasy Portraits: Use green and yellow gels to create a magical or ethereal feel.
* Surreal Portraits: Use unexpected color combinations and abstract compositions to create surreal and dreamlike images.
* Neon Portraits: Use bright, saturated colors like pink, green, and blue to mimic the look of neon signs.
* Duotone Portraits: Use two complementary or contrasting colors to create a classic duotone effect.
In conclusion, colored gels are a powerful tool for creating unique and expressive portraits. By understanding the basics of lighting, color theory, and experimentation, you can unlock a world of creative possibilities and take your portrait photography to the next level.
