Should I activate the flash function of the smartphone camera when using the JBL PROSCAN app?
The flash and torch functions are deactivated within the JBL PROSCAN app. Uniform and shadow-free illumination is essential for the precise performance of the test with exact results. Occasional shadows or over-illumination cause faulty measurement results due to the sensitive "eyes" of the smartphone camera, which aligns the colour dots of the JBL PROSCAN COLORCARD. A daylight-bright room or a measurement under the open sky / at the window always ensure the right light. The COLORCARD takes over the interpretation through the lighting mood and different camera types. Artificial light with strong colouration should be avoided.
