My latest video explains the Sunny 16 Rule. A guide on how best to judge your lighting conditions and for using the correct settings to provide you with the best exposure. It’s not a perfect rule and has some limitations. However, if you’re learning photography and would like to turn off the “auto” options, this will help you. Especially if you do not have access to a light meter.
The first thing we need to do is to set our shutter speed. We do this by selecting the speed that is the closest match to our film ISO. 200iso, 250th of a second. 400iso, 500th of a second and so on. We then leave this setting alone and move to the aperture. The f-stop needs to reflect the lighting conditions that are in the environment in which you are shooting. Bright sunshine, f16. Slightly cloudy, f8 and so on. Watch the video and then go out and practice.
Let me know how you get on.
