Using focal lock is fairly easy even for beginners to digital photography or first-time digital camera owners. Here is a list of the steps:
1. Set up the shot by getting your subject into the position and pose you want, or pick the natural element you wish to shoot.
2. Then, zoom in so that the main focus of your photo is centered in frame. Most times, you can do this by using the camera’s zoom features, but I’ve encountered problems on some cameras with this method, so to avoid this I generally just move myself in until the subject in centered, unless I am taking shots at too great a distance for this to be practical.
3. Press the shutter half way down. On a digital camera, there should be an indication when focal lock is engaged. On my current Nikon camera, there is a beep and a red box appears around the point my camera is now focusing on. On other cameras I’ve used there is a light, a box, or some other indicator.
4. Once you know the camera is focusing where you want it to, you can set the camera to frame the shot however you want to, but don’t let go of the button. Letting the shutter button up will cause your camera loose the focus and you’ll have to find the focal point all over again.
5. Once you are satisfied with the frame and focus, you can press the shutter button the rest of the way down and take your picture.
This process takes just a few seconds and will ensure your pictures come out the way you want them to and eliminate many focusing frustrations you may be having.
