What does opengate photography mean?

It means that the membrane door is fully open. It can record the maximum resolution that the sensor can record, but it will add masks according to the frame settings in the actual machine. To get all the data, you need to remove this mask.

The word "OpenGate" cannot be directly translated as "open door", but it is usually called full pixel imaging or full door opening in the industry. This is different from cutting or over-mining. Cutting only uses part of the sensor. Open the gate or completely open the film door to completely release the sensor pixel information. On some high-end models, this feature requires a special fee.
