while trying to take a photo of my dog , the camera focuses on his eyes but everything else is out of focus , how can i increase the area for the auto focus to focus on

If I understand you correctly, you shoot with a very large aperture which means a narrow depth of field. To increase your depth of field, you will have to stop down your lens.

This article should explain a lot:
Depth of field - Wikipedia, the free encyclopedia


I apologize if I misinterpreted your question.

You're welcome

I also recommend reading 'Understanding exposure' by Bryan Peterson. It explains all the basics of aperture, shutter and iso. A very good read for a beginner. (I've read it myself )

I'd second kskjon's recommendation of 'Understanding Exposure' by Bryan Peterson. Here's a link to it on Amazon.com:
