Professional colour-correction gel roll

This Lee Filters 3/4 C.T. Blue gel roll converts tungsten lighting to a cooler, daylight balance for accurate colour rendition. The 48 by 25 foot roll on a one-inch core suits studio photographers and videographers who need large, custom-cut sheets for multiple fixtures.

Verify fixture dimensions and heat output

Measure each light source to confirm the 48-inch width covers the aperture and that the gel can be trimmed to shape. Ensure the fixtures run within the filter’s rated heat resistance so the material remains stable during long sessions.

Roll format enables custom sizing

The continuous 25-foot length lets you cut exact pieces for fresnels, panels or windows without waste. A standard one-inch core fits common gel frames and holders, so the roll integrates directly into existing grip equipment.

Questions about this item

What comes in the box and do I need to buy a holder or core separately?

The roll ships on a 1-inch core ready to mount on standard gel frames or filter holders; frames and holders are sold separately.

How do I decide between the 48-inch width and the 25-foot length for my setup?

Choose the 48-inch width to cover large fixtures or multiple lights at once; the 25-foot length lets you cut many smaller pieces for ongoing jobs.

What does the 3/4 C.T. Blue rating actually do to the light on set?

It converts tungsten sources toward daylight by raising the colour temperature roughly three-quarters of a full CTO step, cooling the output for mixed-light balance.
