Using Colored Gels to Create Unique and Creative Portraits
Colored gels, or gels as they're often called, are thin sheets of translucent plastic placed in front of your light source to change its color. They are a fantastic tool for adding drama, mood, and visual interest to portraits, transforming ordinary shots into something truly unique and creative.
Here's a breakdown of how to use colored gels effectively:
1. Understanding the Basics:
* What are Gels? They come in various colors, densities, and sizes. They're usually made of heat-resistant plastic or polyester to withstand the heat from continuous lights or flashes.
* Why Use Them? Gels offer a wide range of possibilities:
* Add Mood & Atmosphere: Warm colors (reds, oranges, yellows) evoke warmth, passion, and energy. Cool colors (blues, greens, purples) create a sense of calmness, mystery, or coldness.
* Creative Effects: Use them to create interesting color contrasts, simulate specific lighting conditions (like a neon sign), or simply add a pop of color.
* Color Correction: While less common in creative portraits, gels can be used to correct the color temperature of a light source to match ambient lighting.
* Separation and Emphasis: Use different colors to separate the subject from the background or to highlight specific features.
* Gel Types:
* Color Correction Gels: Adjust color temperature (e.g., CTO - Color Temperature Orange, to warm up a cool light).
* Color Effects Gels: Produce vibrant colors for creative effects.
* Neutral Density Gels: Reduce light output without changing color.
2. Essential Equipment:
* Gels: Start with a basic set of primary colors (red, blue, green, yellow) and some warmer (orange, amber) and cooler (cyan, magenta) tones. Gel sample packs are a good way to explore different options.
* Light Source:
* Strobes/Flashes: Generally preferred for their power and short flash duration.
* Continuous Lights (LEDs, Halogen): Use caution as some gels can melt under the heat of high-wattage lights. Make sure your gels are rated for the type of light you are using. LED lights are generally safe.
* Gel Holders/Speedlight Gels: Devices to attach the gels to your light source. These can range from simple spring clips to dedicated gel holders with grids or snoots. Speedlight gels are often pre-cut to fit standard speedlights.
* Light Stands: To position your lights.
* Light Modifiers (Optional): Softboxes, umbrellas, grids, snoots can be used in conjunction with gels to further control the light.
* Tape (Gaffer Tape): For securing gels temporarily. Never use regular tape on light sources! It can melt and become a safety hazard.
3. Lighting Setups and Techniques:
Here are a few common lighting setups using colored gels:
* Single Light with Gel: The simplest approach. Place a single light with a gel on it to illuminate your subject from one side. Experiment with different angles and gel colors to see how it affects the mood.
* Example: Red gel for a dramatic and sensual effect, or blue gel for a cool and mysterious look.
* Two Lights with Complementary Colors: Use two lights, each with a different gel color (e.g., red and blue, orange and teal, green and magenta). Position them on opposite sides of the subject for a striking and dynamic look.
* Example: Orange and Teal is a very popular combination often seen in movies and photographs.
* Background Light with Gel: Use a light with a gel to illuminate the background, creating a wash of color that contrasts with your subject. This can help to separate the subject from the background and add depth.
* Example: A neutral background with a blue gel creates a cool and modern feel.
* Rim Light with Gel: Place a light with a gel behind the subject to create a colored rim light, outlining their silhouette. This is a great way to add dimension and drama.
* Example: A red rim light can make the subject appear powerful and energetic.
* Split Lighting with Gels: Light one side of the face with one gel color and the other side with a different gel color. This creates a dramatic and contrasting look.
* Example: One side lit with a warm yellow and the other with a cool blue.
* Mixed Lighting (Gels + Natural Light): Use gels to augment or contrast with natural light. For example, use a gelled flash to add a pop of color to a natural light portrait.
* Gels on Multiple Lights: Get creative by using different gel colors on multiple lights to create a complex and layered lighting effect.
4. Practical Tips for Using Gels:
* Start Simple: Don't try to do too much at once. Begin with a single light and a single gel color, then gradually add more complexity.
* Control Your Ambient Light: Dim the ambient light as much as possible to allow the gel colors to truly shine.
* Experiment with Light Modifiers: Use softboxes, umbrellas, and grids to shape and control the light from your gelled flashes. Grids are particularly useful for preventing light spill onto the background.
* Distance Matters: The further the light source is from the subject, the softer the light will be.
* Use a Light Meter: A light meter can help you to accurately measure the light output of your gelled flashes. This is crucial when you are using multiple lights.
* Shoot in RAW: Shooting in RAW format allows you to adjust the white balance and color temperature in post-processing. This gives you more flexibility to fine-tune the colors in your images.
* White Balance: Set your white balance *after* applying the gels. Often, "Tungsten" or "Fluorescent" presets can work well as a starting point. Experiment to find what looks best. If shooting RAW, you can adjust this in post.
* Consider Skin Tones: Certain gel colors can make skin tones look unnatural or unhealthy. Be mindful of how the gel color is affecting your subject's complexion and adjust accordingly. Often, it's best to not have a gel directly on the face.
* Be Mindful of Color Theory: Think about the color wheel and how different colors interact with each other. Complementary colors (e.g., red and green, blue and orange) can create a visually striking contrast, while analogous colors (e.g., blue and purple, yellow and orange) can create a more harmonious look.
* Pay Attention to Shadows: Colored gels can create interesting shadows. Experiment with the placement of your lights to see how the shadows fall on your subject.
* Don't Overdo It: While gels can be a lot of fun, it's important to use them in moderation. Too much color can be distracting and overwhelming. The best gelled portraits often have a subtle and nuanced use of color.
* Post-Processing: You can further enhance the colors and effects of your gelled portraits in post-processing using software like Adobe Photoshop or Lightroom. Adjust color balance, contrast, and saturation to achieve your desired look.
* Practice, Practice, Practice: The best way to learn how to use colored gels effectively is to experiment and practice. Try different setups, colors, and techniques until you find what works best for you.
* Safety First: Always use heat-resistant gels and be mindful of the heat generated by your light sources. Never leave lights unattended. Keep gels away from open flames.
5. Examples of Creative Gel Applications:
* Cyberpunk Aesthetic: Use neon pinks and blues for a futuristic, high-tech look.
* Film Noir Inspired: Employ deep reds and cool blues to create a dramatic and mysterious atmosphere.
* Fantasy/Dreamlike: Combine pastel colors like lavender and baby blue for a soft and ethereal feel.
* Abstract Color Play: Use multiple lights with different gel colors to create abstract patterns and shapes on the subject.
* Retro/Vintage: Experiment with warm tones like orange, amber, and yellow to evoke a sense of nostalgia.
In conclusion, colored gels are a powerful tool for creating unique and creative portraits. By understanding the basics of color theory, lighting techniques, and equipment, you can unlock a world of possibilities and transform your portraits into works of art. Don't be afraid to experiment and have fun!
