Auto Focus Dilemma!!

Most of the digital cameras operate in Auto Focus (AF) mode in which camera`s focus on the subject in the center area of the screen.

Consider the photo below with correct focus. When the focus is correct the subject is sharp and rest of picture in background is blurred.
For example check pictures below with correct focus. Background is blurred and subject (boy) is sharp. This is correct.



Correct focus again !!

However, there are some potential disadvantages with auto focus. It will fail when the subject is not in the center of screen or when shooting low contrast images and fast moving objects.

For example the image below where the subject (flower) is not in center of the screen. Simplify moving the subject into the center could have solved the problem but there will times then subject is not position centrally.





In picture below Subject is in the center but still the focus is on the background. Subject is blurred. This is incorrect image.


There are ways to solve the Auto focusing problem .. coming soon...stay tuned.
