Ways to Save
Quantum's TTL adapters for FreeWire wireless transceivers let your camera control flash exposure without wires. For location portraiture (beach, desert, park, etc.) use wireless TTL when photographing subjects at longer distances, when TTL cables are not practical. For commercial photography mount a Qflash in a light box and shoot wireless TTL for camera controlled soft lighting. Quantum's wireless TTL adapters work with both Qflash T & Qflash X series.
