I was wondering, how often does everyone use their lens hoods and why? I have one lens and bought the hood for it. When outdoors, I always have my lens hood on; mainly keep stray light from entering my lens. Most the time, outdoors during daylight hours I have a CPol protecting my lens + hood. Indoors, I still, always have my hood one but no filters. Why, I'm not quite sure. If anything, lens protection. Do I really need to have my hood on 24/7; indoors and out? Do you know of any reason why I should take my lens hood off indoors or if the hood could mess up my indoor photographs? Sorry for so many questions but I'm just curious. Thanks in advance.
