Cameras need light and when there’s not enough of it the picture taker has a couple of options. A tripod is the preferable option and I’ll cover that in another tip. So lets talk about ISO. In the days of film you couldn’t change the ISO easily  You had to change the film or using exposure compensation “push” or “pull” the film a couple of stops but you couldn’t change back again until you changed the film again. But now the ISO can be changed at a whim. All cameras, including compacts and smartphones these days, have an ISO setting. So there are two options. Have the ISO setting on auto which is fine for the majority of the time. But auto is usually set at a maximum of say 1600 which may not be high enough. Alternatively change the ISO setting to suit the conditions. E.g. in low light select a high ISO. However whilst the top end DSLR’s have amazing results from ridiculously high ISO’s there are some models where grain or noise becomes more pronounced the higher you go. So its worth taking a few images at various settings to see how your model performs at high ISO’s. Having said that grain does add mood to certain scenes. For now though, find that ISO setting!
