Transcription: What you see through the viewfinder can be deceptive. The viewfinder shows the scene with the aperture wide open, resulting in a shallow depth of field. When you click the shutter to take the photo, the aperture stops down to the appropriate f-stop. Therefore, elements in the viewfinder which initially appear blurred may end up sharp. This often happens when using a small aperture opening like f-22. There are two straightforward solutions. Ignore the viewfinder and rely on the printed depth of field tables for each f-stop. or use the aperture preview button on your camera if it has one.
