What I learnt about camera exposure is that different light exposures exist based on whether the light is indoor or outdoor. It’s obvious that being outside is brighter than being inside a classroom. So, when it comes to the brightness of the light, whether it’s inside or outside. When it comes to that, you’ll need to calibrate your camera so that it’s not overexposed or grainy. All of the modes I learned about the camera taught me that you must make sure you have the proper iOS settings, as well as the shutter speed, because this will decide how the photo will turn out once you’re through. The more iOS there are, the brighter the image will appear.
