Using Colored Gels to Create Unique and Creative Portraits
Colored gels can transform a portrait from ordinary to extraordinary. They add mood, drama, and a unique visual flair that's hard to achieve with just natural light. Here's a breakdown of how to use them effectively:
1. Understanding the Basics
* What are colored gels? They are translucent sheets of colored plastic or acetate placed in front of a light source to change the color of the light it emits.
* Types of Gels:
* Corrective Gels: Used to modify existing light, like converting tungsten light to daylight or vice versa.
* Creative/Color Gels: Designed to add color and create interesting effects. They come in a vast range of hues, from vibrant reds and blues to subtle pastels.
* Gel Holders: You'll need a way to attach the gels to your lights. Common options include:
* Speedlight Gel Holders: Designed specifically for attaching gels to speedlights.
* Clip-On Gel Holders: Can be clipped onto the front of reflectors or barn doors.
* Gel Frames: Large frames that hold gels for studio strobes.
* Gaffer Tape (emergency solution): While not ideal, gaffer tape can temporarily hold gels in place. Just be careful they don't melt from the heat.
* Light Sources: You can use colored gels with:
* Speedlights (Flashes): Portable and versatile, excellent for on-location shoots.
* Studio Strobes: Powerful and consistent light source, ideal for studio work.
* LED Lights: Often don't get as hot as strobes, so less likely to melt the gel, and allow for a continuous light that you can preview.
2. Planning Your Shoot
* Concept is Key: Don't just throw gels on haphazardly. Start with a clear idea of the mood, style, and story you want to tell. Consider:
* Color Psychology: Colors evoke different emotions. Red can signify passion, anger, or danger. Blue can represent calmness, sadness, or trust. Research color psychology to make informed decisions.
* Subject's Personality: Consider the subject's personality and choose colors that complement their character.
* Wardrobe and Background: Ensure the colors of the gels work well with the subject's clothing and the background. Neutral clothing and backgrounds are generally easier to work with.
* Sketch It Out: Visualizing your concept through sketches or mood boards can help you refine your ideas.
* Consider the Mood: Are you going for a dramatic, moody look, a vibrant and energetic feel, or something more subtle and ethereal?
3. Gel Setups: Ideas and Techniques
Here are some common gel setups, with explanations and tips:
* Single Gel – Background Color:
* Setup: Place a gelled light source behind the subject, aiming at the background. Use a second (un-gelled or a complementary gel) for the main subject light.
* Effect: Creates a visually striking backdrop and separates the subject from the background.
* Example: Blue gel on the background, warm white (or slightly gelled warm) for the subject.
* Single Gel – Rim Light:
* Setup: Place a gelled light to the side or slightly behind the subject. This creates a colored outline or "rim" of light along their silhouette. Use a second light for the main subject.
* Effect: Adds depth and drama, highlighting the subject's shape.
* Example: Red gel as a rim light, soft white light on the front of the subject.
* Two Gels – Split Lighting:
* Setup: Use two lights, each with a different colored gel. Position them on opposite sides of the subject.
* Effect: Creates a visually stunning effect with half the subject bathed in one color and the other half in another.
* Example: Blue gel on one side, red gel on the other. Experiment with complementary colors like orange and blue for a dynamic look.
* Two Gels – Layered Color:
* Setup: Use two gels on a single light source, placing one on top of the other.
* Effect: Creates a unique and unexpected color blend.
* Example: Combine a cyan gel with a yellow gel to create a green light.
* Subtle Color Pops:
* Setup: Use a single, subtly colored gel on your main light or fill light.
* Effect: Adds a hint of color and mood without being overpowering.
* Example: A very light lavender or peach gel on the main light to create a soft and flattering glow.
* Gel + Gobo:
* Setup: Use a gobo (a stencil placed in front of a light) along with a colored gel.
* Effect: Projects colored patterns onto the subject or background, adding texture and visual interest.
* Example: Use a leaf pattern gobo with a green gel to simulate dappled sunlight.
4. Key Considerations & Tips
* Light Metering: Gels affect light intensity. Use a light meter to accurately measure the exposure and adjust your camera settings accordingly.
* White Balance: Your white balance will be significantly affected by the gels. You can:
* Adjust in Camera: Experiment with different white balance presets (e.g., tungsten, daylight) to see what works best.
* Custom White Balance: Take a photo of a gray card illuminated by the gelled light and use that to set a custom white balance in camera.
* Post-Processing: Shoot in RAW format and adjust the white balance in post-processing.
* Power Settings: Start with low power settings on your lights and gradually increase them until you achieve the desired effect. This helps prevent overexposure and allows you to fine-tune the color intensity.
* Distance: The distance between the light source and the subject affects the spread and intensity of the color.
* Diffusion: Use diffusion panels or softboxes to soften the light and create more pleasing gradients.
* Experiment! Don't be afraid to try different combinations of gels, light placements, and camera settings. This is where the real creativity happens.
* Skin Tones: Be mindful of how gels affect skin tones. Some colors can make skin look unnatural or unhealthy. Neutral or slightly warm gels are generally more flattering for skin.
* Gel Strength: Gels come in different densities. A full-strength gel will have a more intense color effect than a half or quarter strength gel.
* Safety: Always use heat-resistant gels, especially with high-powered lights. Keep gels away from direct contact with the light bulb or element to prevent melting or fire hazards.
5. Post-Processing
* Fine-Tune Colors: You can further enhance the colors and adjust the overall look of your portrait in post-processing software like Adobe Photoshop or Lightroom.
* Adjust White Balance: Refine the white balance to ensure accurate skin tones and overall color balance.
* Dodge and Burn: Use dodging and burning techniques to highlight specific areas and add depth to the image.
* Color Grading: Experiment with color grading to further refine the mood and style of your portrait.
Example Scenario:
Let's say you want to create a portrait with a futuristic, cyberpunk vibe.
1. Concept: Dark, moody, futuristic.
2. Color Palette: Blues, purples, and cyans.
3. Setup:
* Main Light: Softbox with a cyan gel.
* Rim Light: Speedlight with a purple gel positioned behind the subject.
* Background: Dark grey seamless paper or wall.
4. Subject: Wearing dark clothing with metallic accents.
5. Post-Processing: Enhance the blues and purples, add a slight vignette, and sharpen the image.
In Conclusion:
Using colored gels can be a fun and rewarding way to elevate your portrait photography. By understanding the fundamentals, experimenting with different techniques, and carefully considering your concept, you can create stunning and unique portraits that stand out from the crowd. So grab some gels, get creative, and start experimenting! Good luck!
