Profoto Gel Kit for A1 Flash

The Profoto Gel Kit for A1 Flash contains four light balancing filters that neatly fit into the supplied Gel Holder, which quickly clicks onto the A1’s magnetic mount. The Full, 1/2 and 1/4 CTO filters are basically graduated conversion filters that warm the A1’s daylight-balanced output. The full gel is a complete conversion to approximately 3200K, while the 1/2 is aggressively warm to match other fixtures, or for creative effect. The 1/4 CTO provides a warm late afternoon look. Lastly, the 1/2 Plus Green filter helps balance the output with fluorescent lights.
