DoFus: Depth of field and us.

Many people ask me about Dof (Depth of field) or generally they would ask “how to get the background totally blurred?”. There are many tutorials and blogs about it online, but I am gonna make it very short and easy for you. 

A camera can only focus its lens at a single point, but there’s a huge area that stretches in front of and behind this focus point that still appears sharp. That area is totally out of focus and blurred. 

To understand its mechanics or how it works is very easy. One doesn’t need to complex tables of f stop and its mathematical explanations. All you need is a pen or a pencil. Take a pen or a pencil and hold it out. Hold is as far as you can, now focus on its tip. When you do you can see the things behind pretty clearly (still keeping the eye on the tip). Now slowly move the pencil or the pen you are holding closer to your eyes, now the background seems to be blurring out, isn’t it? Thats exactly how a camera lens also works.

I wanna share something with you. When I bought my first DSLR 7 years back, I had clicked this picture below with it. I remember it was my 4th picture from that camera and I had no idea about what DoF is then. But this came out quite well.

Thank you, hope you found it useful. Keeping clicking and keep learning. Shoot RAW.
