About

GR Control

Read full description

GR Control turns your phone into a wireless remote for your Ricoh GR so you can step into the frame while staying in full control. Perfect for travel selfies, group shots, or studio tethering. No extra hardware. No cables. Just open the app, connect and shoot. [For travel photographers] You're always behind the lens, so you're almost never in the shot. GR Control changes that. Set up your frame, step into it, and trigger the shutter from your phone. No asking strangers, no missing yourself from your own trip. [For street photographers] Street photography lives in unguarded moments. But the second your camera goes up, faces change, and whatever was real a moment ago isn't anymore. GR Control helps you avoid that by keeping the camera down. Mount low, frame from your phone, and shoot without anyone noticing. Live View lets you compose from any angle, such as ground level, overhead, or around corners. The shot looks natural because it was. [For studio and tethered shooting] With high-speed image sync, GR Control transfers each shot to your phone or tablet automatically, the moment you press the shutter. Review full images on a larger screen without pulling cards or running cables. Your subject stays ready, your session stays moving, and nothing breaks the rhythm. [Key Features] - Live View — real-time preview on your phone screen for precise framing. - Full camera control — Aperture, Shutter Speed, ISO, EV, White Balance, Metering Mode, Drive Mode, Focus Mode, Self-timer, Image Control effects, and more. - Image sync & Wireless tethering — automatic photo transfer for quick review after every shot. - Offline gallery — browse and review synced images even when the camera is off.
