A lens hood is a small attachment placed at the front of a camera lens. ðž Its primary purpose is to block stray light from hitting the lens, which can cause unwanted glare or lens flare in your photos. Think of it as sunglasses for your camera. ð By preventing light from entering at extreme angles, it improves contrast and color saturation in your images. It also offers some physical protection for the lens itself, guarding against accidental bumps and scratches.
