Get Precise Color Control with the Top 5 Gel Filters for Correction

Whether you’re shooting photos or videos, getting accurate colors is crucial for creating professional, appealing results. But lighting conditions don’t always cooperate, and you’re left with ugly color casts or scenes that just don’t look natural.

That’s where gel filters come to the rescue! These thin colored sheets can be attached to your camera or lighting and provide precise color modifications to get scenes looking their best. But with so many gel options out there, how do you know which are the best for color correction?

In this photo blog, we’ll be exploring the top 5 gel filter recommendations for balancing colors and fixing color casts. You’ll learn the ideal situations for using each filter, their pros and cons, and see real before and after examples showing these gels in action.

If you want to gain total control over the colors in your images and videos, then adding these versatile gel filters to your toolkit is a must! Let’s dive in and up your color correction game.

A Brief Introduction to Using Gels for Color Control

Before jumping into the top gel filter picks, let’s look at what exactly these colored filters are and how they manipulate light.

Gel filters, also called color correction gels or color effect gels, are thin, translucent sheets of plastic or polycarbonate that professional photographers and videographers attach over their light sources to alter the color quality of the emitted light.

They come in a wide range of standardized colors and densities, and work by absorbing or blocking certain wavelengths of the visible color spectrum while allowing others to pass through. This subtractive color mixing lets you transform the look of scenes with just a single gel.

Some key color theory principles that are helpful to understand when working with gels:

  • Color temperature – this refers to the warmness or coolness of light, measured in degrees Kelvin (K). Lower K values are warmer, while higher values are cooler blue and white light.
  • Tint – the amount of green or magenta in a light source, which affects the overall color cast.
  • Saturation – the intensity and richness of colors. Filters lower saturation by absorbing more light.

By manipulating these core attributes, gels can effectively neutralize or remove color casts, create color effects for stylistic purposes, or match the color between multiple light sources. Now let’s look at how to choose the right gel filter for your needs.

Factors to Consider When Selecting Gel Filters

With hundreds of gel filter options out there, it can be tricky to decide which ones are right for your shoot and lighting scenario. Here are some key considerations to keep in mind:

  • Existing light color and color temperature – Analyze the lighting you already have on location so you know what color issues need correction. Is it very warm, cool, green, magenta, etc?
  • Your goals – Are you looking to balance multiple lights, enhance color accuracy, create a stylized effect, or meet a certain final color temperature? This determines if you need a subtle correction gel or something more bold.
  • Color correction gels vs. creative effect gels – Make sure you select a filter designed for either balancing and correction or more extreme creative impact. These are formulated differently.
  • Gel density – Lighter (lower) densities cause subtler changes, while heavier (higher) densities create more dramatic modifications for intense lighting mismatches.
  • Testing gels beforehand – Try out gels and compare results before committing to the best option. Appearances can vary on camera vs. in person.

Keeping these factors in mind will ensure you choose the right gel filter for the job!

The Top 5 Gel Filters for Color Correction and Adjustment

Now that you know how to select the ideal gel filter, let’s look at the top recommendations in 5 key color categories.

1. CTO – Balancing Cooler Light Sources

Color Temperature Orange gel filters lower color temperature and add warmth to a scene. They counteract the bluish, cool lighting from daylight or electronic flash.

Ideal uses:

  • Balancing midday sun or flash with warm artificial light indoors
  • Warming subjects lit by open shade or overcast sky
  • Matching the color temperature of tungsten and flash lighting

Pros:

  • Provides a neutral, balanced look with mixed lighting
  • Warms up skin tones that look too blue or cold

Cons:

  • Can mute blues and greens too much if too strong of a gel is used

2. CTB – Balancing Warmer Light Sources

Color Temperature Blue gels raise color temperature and add coolness to a scene. They counteract the yellow/orange light from tungsten bulbs or at sunrise/sunset.

Ideal uses:

  • Balancing incandescent or sunrise lighting with daylight
  • Matching lighting to the cool look of shade or open sky
  • Neutralizing scenes where sunlight reflects warmly off buildings or pavement

Pros:

  • Removes warm color casts for accurate, natural colors
  • Makes lighting consistently blue across multiple sources

Cons:

  • Can desaturate warm colors like yellows, oranges and reds too much

3. Plus Green – Neutralizing Magenta Color Casts

The Plus Green gel reduces magenta or pink color casts from some light sources. It’s essentially the opposite of a minus green filter.

Ideal uses:

  • Balancing magenta-leaning fluorescent or LED lights
  • Correcting purple fringing from lenses
  • Neutralizing pink sunsets or blue hour lighting

Pros:

  • Removes strong magenta casts from modern light sources
  • Makes greens properly saturated and vivid

Cons:

  • Can dilute bold magenta colors like fuchsia too much
  • Not useful if there is no unwanted magenta in scene

4. Minus Green – Neutralizing Green Color Casts

The Minus Green gel is the opposite of the Plus Green filter. It reduces green color casts from some light sources.

Ideal uses:

  • Balancing green-leaning fluorescent or mercury vapor lights
  • Correcting green color fringing from lenses
  • Neutralizing green color casts from foliage reflections

Pros:

  • Removes unwanted green casts from artificial lights
  • Makes reds and magentas properly vivid and saturated

Cons:

  • Can reduce natural green colors too much if overdone
  • Not useful if no green color cast needs removal

5. Straw/Yellow – Warming While Retaining Highlights

Straw or Yellow gels add warmth while still allowing blue highlights to retain punch and pop. They provide a nice balance.

Ideal uses:

  • Warming subjects while keeping skintones bright
  • Adding richness without overly saturating warm tones
  • Retaining highlight sparkle in blue skies, water, eyes, etc.

Pros:

  • Warms with subtlety and retaining vibrant colors
  • Prevents highlights from blowing out or losing detail

Cons:

  • Won’t fully correct strong blue color casts from cool lighting

FAQ – Common Gel Filter Questions Answered

If you’re new to using gels, here are answers to some frequently asked questions:

How do you securely attach gels? Use gaffer’s tape on the edges of gels, spring clamps, gel holders, and filter frames to affix them to lights without adhesives touching the gel itself.

What light intensity loss occurs with gels? Most correction gels cut up to a stop of light or less. Higher density creative gels can cut 2 stops or more.

Can you layer multiple gels? Yes, you can combine gels for more nuanced color balancing. But limit layers to 2-3 for sufficient light transmission.

What are good gel brands and sources to buy from?
Rosco, Lee Filters and GamColor are top professional gel brands. Buy from photography retailers or rental houses.

How can you modify gels if an exact color match isn’t available? Use gel diffusion sheets or mix the gel color with a neutral density filter to tweak the strength.
