I am just starting out with this whole photography thing. I was taking some pictures of my friends band in his studio/basement, the lighting was weird, darker but they had LED lights on the ceiling as well as very dim incandescent lighting. I had the ISO set to different levels to experiment with getting rid of the noise, without using a flash. I was using the flash because I could not figure how to get a sharp, clear image without it. What should I do to get those images sharp and clear without the flash?? 1. I 2. 3.
