I took some pictures of my little cousins pageant and i took the opportunity to whip out the camera and try my luck at doing full manual shots. These shots were takin at 1/60, iso 6400, f 5.0. I noticed that they are extremely grainy even just viewing them on my laptop. So i wanted to ask is it because of the super high iso i was using? I needed to do this in order to get it bright enough. The lighting was very dim inside and idk if it was just the bulbs or what but thats what it took to get it decent. So what say you TPF?
