Using Colored Gels to Create Unique and Creative Portraits
Colored gels are a fantastic tool for adding dynamism, mood, and artistic flair to your portraits. They're relatively inexpensive and versatile, allowing you to transform your shots in countless ways. Here's a breakdown of how to use them effectively:
1. Understanding Colored Gels:
* What are they? Transparent sheets of colored plastic designed to be placed in front of light sources. They filter the light, changing its color.
* Types of Gels:
* Correction Gels (CTO, CTB, etc.): Used to correct the color temperature of light sources to match each other. For example, CTO (Color Temperature Orange) warms up a cool blue light source.
* Creative Color Gels: Available in a wide range of colors, from vibrant reds and blues to subtle greens and yellows.
* Neutral Density (ND) Gels: Reduce the intensity of light without changing its color. Useful for balancing light ratios.
* Key Properties:
* Color Temperature Shift: How much the gel changes the color temperature of the light.
* Density: How much light the gel blocks. Denser gels are darker and require more light.
2. Essential Gear:
* Colored Gels: A variety pack is a good starting point to experiment with different colors. Rosco and Lee Filters are reputable brands.
* Light Source(s): Speedlights, strobes, or continuous lights (LED panels, etc.) can be used. Speedlights are often a good entry point.
* Gel Holders/Clips: To attach the gels securely to your light source. Velcro, tape, or dedicated gel holders are options.
* Light Stands: To position your lights strategically.
* Light Modifiers (Optional): Softboxes, umbrellas, reflectors, grids, snoots, barn doors. These shape and control the light further, enhancing the effect of the gels.
* Camera & Lens: A portrait lens (50mm, 85mm, etc.) is ideal.
* Trigger (if using off-camera flash): A wireless trigger to fire your flash remotely.
3. Basic Techniques:
* Single Light Setup (Beginner):
* Background Wash: Place a gelled light directly behind your subject to create a colored background.
* Edge Light: Position a gelled light behind and to the side of your subject to create a colored rim light, separating them from the background.
* Key Light with Color: Use a gelled light as your main (key) light. Be mindful of skin tones – subtle colors often work best.
* Two Light Setup (Intermediate):
* Split Lighting: Use two lights, each with a different color gel, positioned on opposite sides of your subject for a dramatic split-color effect.
* Key & Fill with Color: Use one gelled light as the key light and another gelled light as a fill light (perhaps with a more subtle color or no color at all) to soften shadows.
* Background & Subject Separation: Use one gelled light on the background and another (possibly with a different color) on the subject to create separation and visual interest.
* Multiple Light Setups (Advanced): Incorporate more lights and gels to create complex and multi-layered effects.
4. Creative Ideas and Inspiration:
* Complementary Colors: Use colors that are opposite each other on the color wheel (e.g., blue and orange, red and green) for a vibrant and contrasting look.
* Analogous Colors: Use colors that are next to each other on the color wheel (e.g., blue, blue-green, green) for a more harmonious and subtle effect.
* Monochromatic Color Schemes: Use different shades of the same color for a unified and stylish look.
* Emotional Impact: Different colors evoke different emotions. Consider the mood you want to create:
* Red: Passion, energy, danger
* Blue: Calm, serenity, melancholy
* Green: Nature, balance, envy
* Yellow: Happiness, optimism, caution
* Purple: Royalty, mystery, creativity
* Color Blocking: Use distinct blocks of color to create abstract and graphic portraits.
* Experiment with Textures: Use textured backgrounds or props to add another layer of visual interest to your gelled portraits.
* Silhouette: Backlight your subject with a gelled light to create a silhouette effect.
* Abstract Lighting: Use multiple gelled lights and light modifiers to create abstract patterns and shapes on your subject.
5. Tips and Tricks:
* Start Simple: Don't try to do too much at once. Master the basics with one or two lights before adding complexity.
* Use a Light Meter (Optional): A light meter can help you accurately measure the light output from each light source, ensuring consistent exposure.
* Watch Your White Balance: Set your white balance based on the color of the gel you are using. Auto White Balance can sometimes be fooled by strong colors. Experiment with custom white balance settings.
* Pay Attention to Skin Tones: Strong colors can cast unflattering tints on skin. Use gels sparingly on the key light or use them in conjunction with a neutral fill light.
* Use Flagging: Flags (black foam core or fabric) can be used to prevent light spill and control the direction of your light.
* Distance Affects Intensity: The closer the light source to your subject, the more intense the color will appear.
* Test, Test, Test: Experiment with different gel combinations, light positions, and camera settings. The best way to learn is by doing.
* Shoot in RAW: Shooting in RAW format gives you more flexibility to adjust colors and exposure in post-processing.
* Post-Processing: Use post-processing software (e.g., Photoshop, Lightroom) to fine-tune the colors, contrast, and sharpness of your images.
Example Setups:
* Mysterious & Dramatic:
* Key light: Softbox with a deep blue gel, positioned slightly to the side.
* Fill light: Bare bulb flash with a purple gel, aimed at the background.
* Energetic & Vibrant:
* Left: Speedlight with a red gel, pointed at the subject's face.
* Right: Speedlight with a yellow gel, pointed at the subject's face.
* Calm & Serene:
* Background light: Softbox with a light blue gel, placed behind the subject.
* Key light: Reflector to bounce ambient light onto the subject.
By experimenting with these techniques and letting your creativity guide you, you can use colored gels to create truly unique and memorable portraits. Remember to have fun and don't be afraid to break the rules! Good luck!
