What is a Lighting filter or ‘Gel’?

Professional photographic lighting filters are thin, specially tinted sheets of polyester film designed to allow a specific quantity and color of light to pass through them.

Rogue Flash Gels use professional lighting filter material from LEE filters in the UK which we process into kits specially designed for use with small flashes.

Rogue Flash Gels are Labeled with Color, Color Correction, and f/stop Loss Values

We print directly onto Rogue Flash Gels to ensure you always know what gel you’re using and to easily locate the one you need. Rogue Gels are individually labeled with the LEE Filter name of each gel color, as well as the gel’s measured f/stop loss value, and when appropriate, the Kelvin color temperature correction and corresponding camera white balance icon.

All lighting filters absorb light, and the f/stop loss tells you exactly how much light is absorbed by a particular filter. The f/stop loss values printed on our Rogue Gels were measured with a light meter in a controlled test. These values compare the metered exposure of the bare flash with the metered exposure of the flash with the Rogue Gels attached.

Attaching Rogue Flash Gels

You do not need to buy expensive or bulky gel holders, or use sticky hook-and-loop to attach Rogue Flash Gels to your flash. Included with each Rogue Flash Gel kit is a tabbed silicone band which is used to quickly attach Rogue Flash Gels to any standard size speedlight or shoe mount flash. Simply place the Rogue Gel Band around your flash head, then slip the ends of the Rogue Flash Gel under the band.

With a coverage area of 3" x 2.5" (76mm x 63mm) Rogue Flash Gels are large enough to cover even the largest flash heads, and they can be creased or trimmed for smaller flash heads as desired. Their innovative tabbed design allows them to be quickly attached to a wide range of speedlights using the included blue Rogue Gel Band (for standard flashes) or gold Rogue Gel Band (for smaller mirrorless sized-flashes).

CTO Gels

Attach CTO (“CTO” stands for Color Temperature Orange) gels to your flash to color balance your flash to warmer light sources:

• Full CTO for 3,000K ambient light (halogen, incandescent, tungsten)
• 1/2 CTO for 3,500K ambient light (sunrise, sunset)
• 1/4 CTO for 4,200K ambient light (cool white LED)
• 1/8 CTO for 5000K ambient light (warm daylight)

CTB Gels

Attach CTB ("CTB" stands for Color Temperature Blue) gels to your flash to color balance your flash to cooler light sources:

• 1/2 CTB for 10000K ambient light (shade)
• 1/4 CTB for 7100K ambient light (cloudy)

Plus Green Gels

Attach Plus Green gels to your flash in combination with CTO gels to color balance your flash to fluorescent light sources:

• 1/2 Plus Green + 1/2 CTO for 3,500K fluorescent tubes
• 1/2 Plus Green + 1/4 CTO for 4,200K fluorescent tubes
• 1/2 Plus Green + 1/8 CTO for 5,000K fluorescent tubes
• 1/2 Plus Green (do not add CTO) for 5700K fluorescent tubes
