1. Understanding the Basics
* What are Colored Gels? Thin sheets of transparent, colored material (usually plastic) placed in front of a light source to alter its color. They come in a vast array of hues, from vibrant reds and blues to subtle tints and color correction gels.
* Why Use Them? Colored gels offer control over color, mood, and visual interest. They can:
* Create a dramatic atmosphere.
* Complement or contrast skin tones.
* Isolate the subject from the background.
* Correct color casts from ambient light (though this is less common in creative portraiture).
* Add a surreal or artistic flair.
2. Essential Equipment
* Colored Gels: Purchase a set of gels. Starter kits often include popular colors like red, blue, yellow, green, magenta, and orange. Lee Filters and Rosco are reputable brands. You can also find inexpensive kits online, but the quality may vary.
* Lights:
* Strobes/Flashes: Most commonly used. Provide a burst of powerful light that's easily controlled.
* Continuous Lights (LEDs, Halogen): Can be used, but be mindful of heat. Some gels may melt or fade under continuous high heat. LED panels designed for photography are often the best choice for continuous lights. You can see the effect of the gels in real time, which can be very helpful for beginners.
* Light Stands: To position your lights effectively.
* Light Modifiers: Softboxes, umbrellas, snoots, grids, reflectors – to shape and direct the light.
* Gel Holders: Attach gels securely to your lights. Common types include:
* Gel Frames: Slide into slots on the light or modifier.
* Clips/Clamps: For attaching gels to barn doors or other fixtures.
* Velcro: Can be used to attach gels, but be careful with heat from the light.
* Camera: A DSLR or mirrorless camera with manual mode is ideal.
* Lens: Choose a focal length appropriate for portraits (50mm, 85mm, or longer).
3. Planning and Conceptualizing
* Define Your Vision: Before you start shooting, think about the mood and aesthetic you want to create. What story are you trying to tell?
* Color Theory: A basic understanding of color theory is helpful:
* Complementary Colors: Opposite each other on the color wheel (e.g., red and green, blue and orange). Create strong contrast.
* Analogous Colors: Next to each other on the color wheel (e.g., blue, blue-green, green). Create harmonious and softer looks.
* Warm vs. Cool Colors: Warm colors (red, orange, yellow) tend to evoke energy and excitement. Cool colors (blue, green, purple) suggest calmness and serenity.
* Mood Board: Create a mood board with images that inspire you. This helps visualize the final result.
* Model's Skin Tone: Consider how the colors will interact with your model's skin tone. Some colors are more flattering than others. Darker skin tones can handle more saturated colors well.
* Wardrobe: The model's clothing should complement or contrast with the gel colors.
* Background: A neutral background (white, gray, black) is often best to let the gel colors shine. You can also use colored backgrounds or project patterns onto them.
4. Setting Up Your Lights
This is where the fun begins! There are many ways to set up colored lights. Here are some common approaches:
* One Light with Gel: The simplest setup. Place one light with a gel directly on the model. This creates a single, dominant color. Experiment with the light's angle (front, side, above, below) and distance.
* Two Lights, Two Gels: More complex. Use two lights, each with a different gel. You can:
* Complementary Colors: Position one light on each side of the model, using complementary colors for a striking effect.
* Separation/Rim Lighting: Use one light as a key light (main light) and the other as a rim light (behind the model to create a halo effect). Use a different color for each.
* Background Light: Use a gelled light to illuminate the background behind the subject.
* Three or More Lights: Adds even more control and complexity. You can use a key light, fill light (often with a softer color), rim light, and background light, each with different gels.
* Color Gradient/Vignette: Attach a gel to the light and use a snoot or grid to focus the light into a tight beam. Aim the light towards the backdrop, creating a colored vignette effect.
Key Considerations for Setup:
* Distance: The closer the light is to the subject, the softer the light and the stronger the color cast. Moving the light further away creates a harder light with less color.
* Power: Adjust the power of your lights to balance the colors and exposure. Gels reduce the light output, so you may need to increase the power.
* Angle: The angle of the light greatly affects the shadows and highlights.
* Modifiers: Softboxes will diffuse the light and create a softer, more even color. Grids will focus the light and prevent spill.
5. Camera Settings
* Manual Mode (M): Gives you complete control over aperture, shutter speed, and ISO.
* Aperture (f-stop): Choose an aperture based on your desired depth of field. A wider aperture (e.g., f/2.8) creates a shallow depth of field, blurring the background. A narrower aperture (e.g., f/8) creates a greater depth of field, keeping more of the image in focus.
* Shutter Speed: Set your shutter speed to sync with your flash (usually around 1/200th of a second). With continuous lights, adjust to control the ambient light.
* ISO: Keep your ISO as low as possible (e.g., ISO 100) to minimize noise.
* White Balance:
* Custom White Balance: The most accurate method. Take a photo of a gray card under your gelled light and set your white balance based on that image.
* Preset White Balance: Try different presets (e.g., "Flash" or "Tungsten") and see which one looks best.
* Auto White Balance (AWB): Not recommended, as it can struggle with colored lights and may produce inconsistent results. However, it's a starting point.
* Metering: Use your camera's built-in light meter as a guide, but be prepared to adjust your settings based on the results. Since gels affect color and brightness, relying solely on the meter can be tricky. Review your shots on the camera's LCD screen and adjust as needed.
6. Shooting and Experimenting
* Take Test Shots: Before your model arrives (or at the beginning of the shoot), take test shots to dial in your lighting and camera settings.
* Communication with Your Model: Clearly communicate your vision to your model. Provide direction and feedback.
* Move and Adjust: Don't be afraid to move your lights, change gels, and try different angles.
* Embrace Imperfection: Some of the most creative results come from unexpected accidents.
7. Post-Processing
* Color Correction: Adjust white balance, contrast, and saturation in your editing software (e.g., Adobe Lightroom, Capture One).
* Fine-Tune Colors: Make subtle adjustments to the individual colors to achieve your desired look.
* Retouching: Remove blemishes and imperfections.
* Creative Effects: Experiment with color grading, split toning, and other effects to enhance the mood.
Tips for Success
* Start Simple: Begin with one or two lights and gradually increase the complexity as you gain experience.
* Practice, Practice, Practice: The more you experiment with colored gels, the better you'll understand how they work and how to use them effectively.
* Research and Inspiration: Study the work of photographers who use colored gels well. Pay attention to their lighting techniques, color palettes, and compositions.
* Don't Overdo It: Less is often more. Avoid using too many colors or excessive saturation, as this can create a distracting and overwhelming image.
* Safety: Be careful when working with lights and gels. Make sure the gels are properly secured and don't obstruct the light's ventilation.
Specific Creative Ideas
* Monochromatic Portraits: Use different shades of the same color to create a cohesive and elegant look.
* Split Lighting: Divide the subject's face with two complementary colors.
* Silhouette Portraits: Place a colored light behind the subject to create a silhouette effect.
* Projected Patterns: Use gobos (metal or glass stencils) to project patterns onto the subject or background.
* Double Exposure: Combine a regular portrait with a colored gel image for a surreal effect.
* Color Harmony: Create a harmonious color palette by using analogous colors or colors with similar tones.
By understanding the basics of colored gel photography, experimenting with different setups, and embracing your creativity, you can create stunning and unique portraits that stand out from the crowd. Good luck!
