If you think that you have become a good photographer then its time to sit back and think again...If u shooting with a DSLR then u know which eye u have to use to look through the viewfinder...we all take these topics easily but they make a lot of difference...so u have to be sure about the eye to be used...USE YOUR DOMINANT EYE :D

• Extend your arms out in front of you with your palms faced out
• Bring your hands together to form a small triangular hole
• Look through this hole at a fixed object across the room
• Keep looking at the object with both eyes, through the triangle hole
• Slowly pull your hands to your face, still looking at the object
• Bring your hands all the way back to your face
• You just discovered your dominant eye
