Gels are primarily used to modify the color temperature of light, allowing photographers to adjust the overall color balance of their images.

Gels are primarily used to adjust the color temperature of light, while filters are used to create various effects, such as diffusion, color correction, and special effects.

CTO (Color Temperature Orange) gels are commonly used to add warmth to the light, creating an incandescent or tungsten-like look.

CTB (Color Temperature Blue) gels are used to reduce the color temperature of light, making it appear cooler and more daylight-balanced.

ND (Neutral Density) filters are used to reduce the intensity of light without affecting its color, making them useful for controlling exposure and creating shallow depth of field.

Polarizing filters are used to reduce reflections and glare from non-metallic surfaces, such as water, glass, and foliage, enhancing the clarity and saturation of colors.

Diffusion filters are used to create a soft, ethereal look by scattering light and reducing harsh shadows, often used in portrait and fashion photography.

UV (Ultraviolet) filters are used to block ultraviolet light, which can cause a bluish cast in outdoor photographs, especially in high-altitude or coastal areas.

Gels and filters can be used in various combinations and techniques to create unique and artistic effects, such as color splashes, light streaks, and creative color grading.

Gels offer several advantages over filters, including portability, ease of use, flexibility in shaping, and higher temperature tolerance.

Considering the color temperature of the light source is crucial to achieve accurate color reproduction, create specific color effects, and prevent damage to the gels or filters due to excessive heat.

Gels and filters can be used individually or in combination to adjust the color temperature, reduce unwanted color casts, and achieve the desired color balance in an image.

Graduated filters have a gradual transition from one color to another, allowing for smooth color correction across a portion of the image, while solid filters have a uniform color and are used for specific color effects.

Radial ND (Neutral Density) filters are used to create a vignette effect, gradually darkening the edges of the image while keeping the center bright.

Gels and filters can be used in various creative ways to add color to shadows, create color splashes, and combine different colors to achieve unique and artistic effects.
