A range of solutions for softening and spreading a light beam and reducing the contrast ratio between highlight areas. The range includes polyester diffusion filters, frosts, flexi-frosts, perforated diffusion, grid cloths and spun materials all in different densities for a wide range of lighting effects. A note on light balancing vs. conversion gels. CTO and CTB gels also come in a variety of strengths; 1/2 CTO, 1/4 CTO, 1/8 CTO & 1/2 CTB, 1/4 CTB, and 1/8th CTB. Gels at a fraction of the strength are referred to as a light balancing gels. They are useful for warming or cooling certain light sources, as opposed to fully converting a light source.

Please keep in mind that many of the conversions are approximate and are subjective. Chromaticities are given for the Lee gel colors for your convenience. "n/c" denotes that there is no conversion available. These gels are manufactured by companies like Roscoe, Lee and ExpoImaging. Gels come in all sizes from large rolls to precut sheets. My preferences are the Rogue Gels made by ExpoImaging as they are the perfect size for flash heads and are attached using an elastic band. Each gel is marked for its strength and light loss.

13 Dec 2007 A CTB gel converts tungsten light of 3200K to 'daylight' color. So let's look at a Kelvin temperatures chart for various lighting conditions. 13 Dec 2019 Cover a speedlight with a Rosco #3202 Full Blue CTB gel. Again, photograph the chart in RAW.

The quick reference chart shows how each filter alters the color temperature of a GamColor CTB filters will raise the color temperature of an incandescent light 

And you do that with a tungsten gel, also known as a CTO gel. (Color temperature orange.) They can also go the other direction (physically converting a tungsten source into daylight) by using a CTB (color temperature blue) gel. Simple to mount, you just tape or velcro them to the flash. Leave a little space to vent the heat from the tube:

Use CTB gels to color balance flash to shade, or blue sky ambient light sources. Use Plus Green gels in combination with CTO gels to color balance flash to fluorescent ambient light sources. Identify your light source, select the appropriate color correction gel(s), then attach the gel(s) to your flash. This Roscoe 1/4 Blue CTB Color Conversion Gel Filter is traditionally used to convert tungsten lighting to daylight. CTB (Color Temperature Blue) filters are available in a full spectrum of degrees (strengths) which, depending on your needs, can be used to either raise the temperature of your lighting or to create different lighting interpretations.
