If the photo is dark, you can improve it in the following ways: 1) Lower the shutter speed from 1/500 sec to 1/100 sec, or even slower, such as 1/50 sec; 2) Increase the ISO number from ISO 100 to ISO 200/400/800, etc.; 3) Switch the position to allow more ambient light to enter the camera's image sensor through the lens. ✅【Warm Tips】The camera does not display aperture value, has no autofocus or image stabilization. Even slight camera shake will significantly affect image quality. We recommend using a tripod simultaneously to stabilize the image.
