What is the Wake-Up(2-Shot) Method and what digital backs require this?

The “Two-Shot method,” for some One digital backs is a specific procedure required for certain older models, especially when used with other technical camera system.

What is the Two-Shot Method?

Normally, when you press the shutter button on a camera, the digital back “wakes up,” prepares to capture an image, and then captures it. In a “Two-Shot” or “Wake-Up” scenario, the digital back needs a separate signal to wake it up before the camera’s shutter is fired. WakeUp process to save battery power and to reduce the heat noises on picture.

This typically involves:

1. “Wake-Up” Signal: You manually send a signal to the digital back to “wake it up” or put it in a ready state. This is often done by pressing a small button on a specialized “wake-up” cable connected to the digital back’s multi-connector port.
2. Shutter Release: Within a short timeframe (usually a few seconds) after the wake-up signal, you then fire the camera’s shutter to take the picture.

The purpose of this method is often to conserve battery power on the digital back, as it’s not continuously in a “ready” state.

Which Phase One Models Require the Two-Shot Method?

The following models require the Two-Shot method for each shot

• Leaf Credo Series
• PhaseOne P20+P20+ / P21+ / P25+ / P30+ / P45+ (Kodak Sensor)

FYI, These models can use both the Two-Shot method (for battery conservation) and the Single-Shot method (where the back is always ready for capture, consuming more battery).

• PhaseOne P40+ / P65+ (Dalsa Sensor)
• PhaseOne IQ Series

Essential Accessories:

If you need to use the Two-Shot method, you’ll generally require:

• Phase One Multi-Connector (Multi-Cable): This cable connects to the digital back’s multi-connector port.
• Wake-up (Two-Shot) Cable or Converter: This cable typically has a button on it and connects to the multi-connector cable, sending the wake-up signal.
