Sometimes when we are shooting in low light our camera has a problem locking on the focus due to everything being so dark. This tip will work well if you are taking a portrait with a long exposure or just trying to get focus in a dark situation so you can use a little flash. Just about everyone has a cell phone with them so if your subject is too dark for your camera to lock on focus just have them put their cell phone screen next to their face or area you want to be in focus and focus on the lit up screen. After getting focus lock put the phone away and take your picture.
This is also useful if you are trying to take a picture of a still object and need to get focus lock. Just have someone stand next to the subject and turn on the phone long enough to get focus lock.
