Another important tip for when you're taking pictures using available light is to ensure your hands don't shake. I don't have a tripod yet, but much of what I read suggests that getting one will make a big difference. Having the camera steady can ensure that you avoid any blurring. However, without a tripod, there are still options. You can seek out alternative steady surfaces like a table, a wall, the floor, or even use your leg or your knee to avoid ruining your picture.
I plan on trying out these tips and a few others this week and hopefully sharing the photographic results in my next post. Stay tuned!
