1. Gear You'll Need:
* Light Source(s):
* Speedlights (Flashes): Portable, affordable, and versatile. You'll likely want at least two.
* Studio Strobes: More powerful than speedlights, great for overpowering ambient light or using larger modifiers.
* Continuous Lights (LED panels, etc.): Easier to see the effect in real-time, but often less powerful. Not ideal for overpowering bright sunlight.
* Colored Gels:
* Gel Sets: Easily available online. Start with a basic set containing a variety of colors (red, blue, green, yellow, orange, purple).
* Individual Gels: Allows you to get specific shades. Rosco and LEE Filters are reputable brands.
* Gel Holders:
* Speedlight Gel Bands: Elastic bands with pockets for holding gels onto speedlights.
* Gel Holders for Strobes: Designed to clip or attach to the front of studio strobes.
* DIY Options: You can also use gaffer's tape (heat-resistant) to attach gels directly to your lights, but be very careful with heat buildup.
* Light Stands: To position your lights.
* Light Modifiers (Optional):
* Softboxes: Create a soft, even light.
* Umbrellas: Softer than bare bulb, more directional than softboxes.
* Snoots: Concentrate the light into a small, focused area. Great for hair lights or adding small pops of color.
* Barn Doors: Shape the light beam.
* Grids: Control light spill and create more directional light.
* Camera: DSLR or mirrorless with manual mode capabilities.
* Lens: Portrait lens (e.g., 50mm, 85mm) is ideal, but any lens can work.
* Optional:
* Reflector: To bounce light and fill in shadows.
* Light Meter: To precisely measure light output.
* Wireless Triggers: To remotely fire your flashes. Essential for off-camera flash.
* Colored Background Paper/Fabric: To enhance the overall color scheme.
2. Understanding Color Theory (Basic Principles):
* Hue: The actual color (red, blue, green, etc.).
* Saturation: The intensity or purity of the color.
* Brightness/Value: How light or dark the color is.
* Complementary Colors: Colors opposite each other on the color wheel (e.g., red and green, blue and orange). Using them together creates strong contrast.
* Analogous Colors: Colors next to each other on the color wheel (e.g., blue, blue-green, green). They create a harmonious and visually appealing effect.
3. Planning Your Shot:
* Concept: What feeling or mood do you want to create? Think about the story you want to tell. Examples:
* Moody and Dramatic: Dark colors, strong shadows.
* Energetic and Vibrant: Bright, saturated colors, dynamic poses.
* Surreal and Dreamlike: Unusual color combinations, creative lighting patterns.
* Color Palette: Choose a color scheme. Will you use complementary colors, analogous colors, or a monochromatic palette? Sketch out your idea.
* Background: Consider the background color. A neutral background will allow the colored light to stand out. You can use color backgrounds to match your lights for a more vibrant effect.
* Wardrobe: Choose clothing that complements your color scheme. Avoid overly busy patterns.
* Makeup: Subtle makeup is usually best, but you can also use makeup to enhance the colors of the gels (e.g., blue eyeshadow with a blue gel).
* Lighting Setup: Decide how many lights you'll use and where you'll position them.
4. Lighting Techniques and Setups:
Here are some basic lighting setups with colored gels. Experiment and modify them to your liking:
* One-Light Setup (Simplest):
* Place a single light with a gel to one side of your subject.
* Use a reflector on the opposite side to fill in shadows, or leave it for a more dramatic look.
* Two-Light Setup (Classic):
* Split Lighting: Place one light with a gel on the left side and another light with a different gel on the right side. This creates a dramatic and contrasting effect. Experiment with complementary colors.
* Key and Fill: Use one light with a gel as your key light (main light) and another light (without a gel or with a weaker gel) as a fill light to soften the shadows.
* Three-Light Setup (More Control):
* Key, Fill, and Hair Light: Use two lights as described above, and add a third light (with or without a gel) behind the subject as a hair light to separate them from the background.
* Two Backlights, One Front Light: Put two lights with gels behind the subject pointing towards them to create dramatic rim lighting around their body and add one light from the front to light the front of the face.
5. Camera Settings:
* Manual Mode (M): Gives you full control over your exposure.
* ISO: Start with the lowest possible ISO (usually 100) to minimize noise. Increase only if necessary to achieve proper exposure.
* Aperture: Choose an aperture that gives you the desired depth of field. For portraits, f/2.8 to f/5.6 is a good starting point. A wide aperture will create a shallow depth of field, blurring the background.
* Shutter Speed: Set your shutter speed to the maximum sync speed of your flash. This is usually around 1/200th or 1/250th of a second. Using a faster shutter speed than your sync speed will result in a black bar in your image.
* White Balance: Set your white balance to "Flash" if you're using flash, or use custom white balance and meter the light that is hitting the subject.
* Flash Power: Adjust the power of your flashes to achieve proper exposure. Start with low power and increase as needed. You can use a light meter for precise readings.
6. Metering:
* With a Light Meter: Aim the meter towards the light source and take a reading. Adjust your camera settings (aperture, shutter speed, ISO) to match the meter reading.
* Without a Light Meter (Chimping): Take a test shot, review the image on your camera's LCD screen, and adjust your flash power and/or camera settings until you achieve the desired exposure.
* TTL (Through-The-Lens Metering): Some flashes offer TTL metering, which automatically adjusts the flash power based on the camera's exposure settings. This can be a good starting point, but manual control is often preferred for more consistent results.
7. Creative Techniques & Tips:
* Color Combinations:
* Complementary Color Splits: Use complementary colors on opposite sides of the face for a striking contrast.
* Monochromatic: Use different shades of the same color for a subtle and elegant look.
* Analogous Colors: Create a harmonious and visually appealing effect with colors that are close to each other on the color wheel.
* Gel Intensity:
* Double Gels: Stack two gels of the same color to increase the intensity.
* Half-CTO/CTB: Use "Color Temperature Orange" (CTO) or "Color Temperature Blue" (CTB) gels to subtly shift the color temperature of the light. Useful for warming or cooling skin tones.
* Light Modifiers:
* Snoots: Use a snoot to create a spotlight effect.
* Gobos: Use a gobo (a stencil) to project patterns of light onto your subject or background. You can create your own gobos using cardboard or aluminum foil.
* Experiment with Shadows:
* Use hard light to create strong, defined shadows.
* Use soft light to create soft, diffused shadows.
* Fog/Haze: Add fog or haze to your scene to create a dreamy or ethereal effect. The colored light will be more visible in the atmosphere.
* Motion Blur: Combine colored gels with motion blur to create abstract and dynamic images.
* Background Color: Use gels to light your background as well as your subject.
* Skin Tone Considerations: Some colors can make skin tones look unhealthy. Experiment to see what works best. Generally, warmer tones (yellows, oranges) are more flattering than blues and greens. You might want to mix in a less intense white light as a key to get the best skin tones.
* Safety: Never leave lights unattended while gels are attached. Always use heat-resistant gels.
8. Post-Processing:
* Color Correction: Fine-tune the colors in post-processing.
* Dodge and Burn: Enhance the highlights and shadows.
* Sharpening: Add sharpness for a crisp and detailed image.
* Creative Effects: Experiment with color grading and other creative effects.
Important Considerations:
* Heat: Flash units generate heat. Don't use gels that are not heat-resistant, and be cautious about layering gels for too long.
* Gel Degradation: Gels fade over time, especially with prolonged exposure to heat. Replace them when they start to lose their color.
* Model Comfort: Communicate clearly with your model and explain what you're trying to achieve. Make sure they're comfortable with the lighting setup.
* Practice! Experiment with different colors, lighting setups, and camera settings to develop your own style.
By following these tips and techniques, you can use colored gels to create stunning and unique portraits that will set your work apart. Good luck and have fun!
