1. Understanding the Basics
* What are Colored Gels? Thin, translucent sheets of colored plastic that fit over your light source (flash or continuous light). They alter the color of the light it emits.
* Why Use Them?
* Creative Color: Adds vibrant and unusual colors for artistic effects.
* Mood Creation: Colors evoke different emotions (e.g., blue for sadness, red for passion).
* Separation/Isolation: Use contrasting colors to separate the subject from the background.
* Color Correction: Although less common in creative portraiture, gels can subtly balance color temperatures.
* Gear You'll Need:
* Colored Gels: Get a variety pack to experiment with different colors. Rosco and Lee are reputable brands.
* Light Source(s): Speedlights (flashguns) or studio strobes are common. Continuous LED lights can also work. Make sure they are dimmable if using continuous lights.
* Gel Holders/Attachments: These attach to your light source to hold the gels in place. Often specific to your flash/light brand.
* Light Stands: To position your lights.
* Diffusers (Optional): Soften the light coming from the flash, making the color transition smoother.
* Reflectors (Optional): Bounce light to fill in shadows and add highlights.
* Camera: DSLR or mirrorless camera with manual controls.
* Lens: A portrait lens (50mm, 85mm, or longer) is generally preferred.
2. Planning Your Shoot
* Concept/Theme: Determine the overall mood and story you want to tell with your portrait. This will influence your color choices.
* Color Palette: Decide which colors will complement each other or create the desired contrast. Research color theory! Look up things like:
* Complementary Colors: Colors opposite each other on the color wheel (e.g., red and green, blue and orange). These create strong contrast and visual interest.
* Analogous Colors: Colors next to each other on the color wheel (e.g., blue, blue-green, green). These create a harmonious and calming effect.
* Triadic Colors: Three colors equally spaced on the color wheel.
* Lighting Setup: Sketch out your lighting plan. Where will each light be placed? What color gel will be on each light? Consider using a lighting diagram app (e.g., Pocket Softbox).
* Model/Subject: Consider your model's skin tone, clothing, and hair color when choosing gels. Some colors might flatter them more than others.
* Background: Choose a background that complements or contrasts with your chosen colors. A neutral background (white, black, gray) is often a good starting point.
3. Setting Up Your Lights
* Safety First: Be careful when handling lights, especially strobes, as they can get hot.
* Mounting: Securely attach your gel holders to your light sources.
* Gels: Cut the gels to the appropriate size for your holders and insert them.
* Positioning: Place your lights according to your lighting plan. Experiment with different angles and distances.
* Key Light: The main light source. Often gelled.
* Fill Light: A weaker light to fill in shadows. Can be ungelled or have a different colored gel.
* Background Light: A light aimed at the background to add color or separation.
* Rim Light/Hair Light: A light positioned behind the subject to create a halo effect.
* Power Settings: Start with low power settings on your flashes and gradually increase them until you achieve the desired brightness.
4. Camera Settings
* Manual Mode (M): Gives you full control over your exposure.
* ISO: Keep it as low as possible (ISO 100 or 200) to minimize noise.
* Aperture: Choose an aperture that provides the desired depth of field. f/2.8 to f/5.6 is a good starting point for portraits.
* Shutter Speed: Set your shutter speed to the flash sync speed of your camera (usually around 1/200th of a second).
* White Balance: This is crucial. Experiment!
* Custom White Balance: Use a gray card to set a custom white balance. This is the most accurate approach.
* Preset White Balance: Try "Flash" or "Tungsten" depending on the colors you're using.
* Auto White Balance (AWB): Can be unreliable with colored gels.
* Post-Processing: You can adjust white balance in post-processing (Lightroom, Photoshop), but it's better to get it as close as possible in-camera.
* Metering: Use your camera's meter to get a balanced exposure. If you're using flash, your camera's meter might not be accurate. You might need to use a flash meter or rely on your LCD screen and adjust settings accordingly.
5. Shooting and Experimenting
* Take Test Shots: Take a series of test shots to fine-tune your lighting, camera settings, and gel colors.
* Adjust Light Positions and Power: Move the lights around and adjust their power levels to get the look you want.
* Experiment with Different Gels: Try different combinations of colors.
* Vary the Distance: Move the lights closer or farther away to change the intensity and softness of the light.
* Observe Shadows: Pay attention to the shadows created by the gels. They can add depth and dimension to your portraits.
* Pose Your Model: Guide your model with posing and expression to complement the mood and colors you're creating.
6. Post-Processing
* Color Correction: Fine-tune the colors in post-processing to achieve your desired look.
* Exposure Adjustments: Adjust the brightness and contrast of the image.
* Sharpening: Sharpen the image to enhance details.
* Retouching: Retouch any blemishes or imperfections on the skin.
Tips and Tricks
* Start Simple: Begin with a single gel on a single light and gradually add more complexity.
* Diffusion is Key: Use diffusion (softboxes, umbrellas) to soften the light and create smoother color gradients.
* Gel Strength: Gels have different densities (strengths). Some colors might be very saturated, while others are more subtle. Experiment with ND (Neutral Density) gels to control brightness without changing color.
* Color Theory: Learn about color theory to understand how different colors interact with each other.
* Gel Compatibility: Be aware that some gels can melt or fade if used with very high-powered lights.
* Consider Skin Tones: Blues and greens can sometimes make skin look sickly. Warm colors (reds, oranges, yellows) tend to be more flattering.
* Don't Overdo It: Subtlety can be just as effective as bold color.
* Practice, Practice, Practice: The more you experiment, the better you'll become at using colored gels.
Creative Ideas to Try
* Double Lighting: Two lights, each with a different complementary color (e.g., red and cyan).
* Split Lighting: One side of the face lit with one color, the other side with a different color.
* Backlighting: Use gels to create colorful backlights that rim your subject.
* Silhouettes: Use a strong colored backlight to create a silhouette of your subject.
* Abstract Backgrounds: Shine colored lights directly onto a blank wall or backdrop.
* Moody Portraits: Use darker, more saturated colors to create a dramatic and evocative atmosphere.
* Thematic Portraits: Use colors that match a particular theme or holiday (e.g., red and green for Christmas, orange and black for Halloween).
* Monochromatic Portraits: Use different shades and tints of the same color.
By following these steps and experimenting with different techniques, you can create stunning and unique portraits using colored gels. Have fun and let your creativity flow!
