Exposure time or shutter speed is the length of time when the digital sensor inside the camera is exposed to light. The amount of light that reaches the digital sensor is proportional to the exposure time and a larger exposure time means more light will reach the sensor.
The value used in the EORA3D App is presented in milliseconds(ms). The relationship between the exposure time and ISO are dependant on each other to ensure the best results for a scan. Much like a digital camera, the exposure triangle explains this relationship:
The exposure time values here represent the ms values in the EORA3D App i.e. 1/1000 = 0.001 = 1ms.
These values range from 0.1ms to 10ms.
Smartphones do not allow the aperture to be adjusted in the hardware of the device. For this reason, we do not have a setting to adjust the aperture in the EORA3D app.
