1. Understanding Color Theory Basics (Helpful, but not mandatory):
* Primary Colors: Red, Yellow, Blue. Mixing these can create almost any other color.
* Secondary Colors: Green (Yellow + Blue), Orange (Red + Yellow), Violet (Red + Blue).
* Complementary Colors: Colors opposite each other on the color wheel. Using these together creates a strong contrast (e.g., Red and Green, Blue and Orange, Yellow and Violet).
* Warm vs. Cool Colors: Warm colors (reds, oranges, yellows) tend to feel energetic and inviting. Cool colors (blues, greens, purples) tend to feel calm and mysterious.
2. Essential Gear:
* Colored Gels: A set of gels is crucial. You can buy pre-cut gels or sheets you cut yourself. Look for gels designed for photography; they're heat-resistant. Popular brands include Rosco, Lee, and others. Start with a basic set of primary colors, then expand as needed.
* Lights: You'll need one or more lights. Speedlights (flash guns), studio strobes, or even continuous LED lights can work.
* Light Stands: To position your lights correctly.
* Gel Holders/Clips: To attach the gels to your lights. These can be simple clips or more sophisticated magnetic holders.
* Light Modifiers (Optional but Recommended): Softboxes, umbrellas, snoots, grids, and barn doors will help shape and control the light and further refine the impact of the gels.
* Light Meter (Optional): A light meter helps you get accurate exposure readings, especially when using multiple lights.
* Background (Optional): A plain background will help the colors stand out more. White, gray, or black are good starting points.
* Camera: Obviously!
3. Setting Up Your Lights and Gels:
* Single Light with a Gel:
* Placement: Place your light to one side of your subject, or directly in front for a more dramatic, flat look. Angle the light to create shadows that enhance the form.
* Gel Attachment: Secure the gel to your light using a gel holder. Make sure the gel is securely attached and doesn't block the light sensor on your flash (if applicable).
* Experimentation: Adjust the power of the light and the angle to see how the color changes the mood of the portrait.
* Two Lights with Gels: This is where things get interesting!
* Complementary Colors: A common setup is using complementary colors on two lights. For example, put a blue gel on one light and an orange gel on the other. Position them on opposite sides of your subject for a dramatic and colorful look.
* Color Separation: Position the lights to light different parts of your subject. One light might illuminate the face, while the other highlights the hair or background.
* Background Light: Use one light with a gel to illuminate the background, and another light (with or without a gel) to light the subject. This can create a striking effect.
* Rim Lighting: Position lights behind the subject as rim lights, each with a different gel. This creates a vibrant outline around the subject.
* Multiple Lights with Gels: For more complex setups, you can use three or more lights. Experiment with different color combinations and light modifiers. You could have a key light, a fill light, and a background light, each with a different color gel.
4. Camera Settings:
* White Balance: This is *crucial*.
* Custom White Balance: The *best* method. Take a picture of a neutral gray card or a white object lit by your gelled lights. Set your camera's custom white balance to that image. This ensures accurate colors.
* Preset White Balance: Try using a preset like "Tungsten" (incandescent) or "Fluorescent." These might get you close, but you'll likely need to adjust the colors in post-processing.
* Auto White Balance (AWB): Avoid AWB. It will try to neutralize the colors from the gels, defeating the purpose.
* ISO: Keep your ISO as low as possible (typically ISO 100) to minimize noise. Increase it only if necessary to achieve a proper exposure.
* Aperture: Choose an aperture that gives you the desired depth of field. Wider apertures (e.g., f/2.8, f/4) will create a shallow depth of field, blurring the background and drawing attention to the subject. Narrower apertures (e.g., f/8, f/11) will give you more depth of field, keeping both the subject and background in focus.
* Shutter Speed: Your shutter speed will be determined by your lighting setup. With flashes, you'll typically be shooting at or below your camera's sync speed (e.g., 1/200th of a second). With continuous lights, you can use a faster shutter speed to control ambient light.
* Shooting in RAW: Always shoot in RAW format. This gives you the most flexibility in post-processing to adjust the white balance, exposure, and colors.
5. Post-Processing:
* White Balance Adjustment: Fine-tune the white balance in your editing software (e.g., Lightroom, Photoshop) if needed.
* Color Correction: Adjust the hue, saturation, and luminance of the colors to achieve your desired look.
* Dodging and Burning: Use dodging and burning to selectively lighten or darken areas of the image, enhancing the contrast and shape.
* Split Toning: Split toning can be used to add subtle color casts to the highlights and shadows, further enhancing the mood of the portrait.
6. Tips and Techniques:
* Experiment! The key to mastering colored gel photography is to experiment with different color combinations, lighting setups, and camera settings. Don't be afraid to try new things and see what works.
* Subtlety vs. Drama: You can use gels for subtle color shifts or bold, dramatic looks. Start with subtle changes and work your way up to more intense effects.
* Less is Often More: Sometimes, using just a touch of color can be more effective than overpowering the image with too much color.
* Skin Tones: Be mindful of how the colors affect skin tones. Certain colors can make skin look unnatural or sickly. You can often correct this in post-processing. Using a very light tint of color on a key light can be effective and less harsh.
* Gel Strength: Gels come in different strengths. A "full" gel will block more light and create a more saturated color, while a "half" or "quarter" gel will be more subtle.
* Distance: The distance between the light and the subject can affect the intensity of the color.
* Use a Model Release: If you're shooting with a model, always get a model release form signed.
* Consider the Theme: Think about the theme or story you want to tell with your portrait. Choose colors that complement the theme.
* Communication with Your Model: Explain your vision to your model, so they can understand the mood and emotion you're trying to create. This will help them pose and express themselves in a way that complements the colors.
Example Setups:
* Cyberpunk/Sci-Fi: Use neon pink and cyan/teal for a futuristic, edgy look.
* Mysterious/Noir: Use deep blues and purples for a sense of mystery and drama.
* Dreamy/Surreal: Use pastel colors like lavender, light blue, and pink for a whimsical, ethereal feel.
* Retro/Vintage: Use warm colors like amber, orange, and sepia for a nostalgic look.
By understanding the basics of color theory, experimenting with different lighting setups, and using post-processing techniques, you can create stunning and unique portraits with colored gels. Have fun and let your creativity shine!
