Earlier photographers relied on focusing screens with special characteristics designed to help manual focusing. Modern focusing screens generally show the metering zones available with the camera as well as the focus points in use, but little more.

Many digital single lens reflex cameras allow the user to replace the provided focusing screen with others as needed. Some replacement focusing screens simply provide a grid to aid with compositions, while others can offer a split-screen or microprisms in the center.
