<\/a>1\/100s at f\/2.8. ISO 400<\/p><\/div>\n
The colours are really nice, but there is a focus problem. I think there are two issues:<\/p>\n
Composition Decision-Making<\/h3>\n
It isn’t really obvious what was meant to be in sharp focus. Is it the padlock, the bolt or both? A bolder, clear decision before taking the picture would help.<\/p>\n
Depth of Field<\/h3>\n
When you’re this close to the subject, even f\/2.8 is going to give a very narrow depth of field. The camera was probably only 30-50cm from the padlock. Some figures might help to reinforce this point:<\/p>\n
- \n
- At 30cm, the total depth of field is only 7.3mm. 3.6mm in front of the subject and 3.7mm behind the subject.<\/li>\n
- At 50cm, the total depth of field is 2.15cm. 1.05 cm in front of the subject and 1.1cm behind. That’s still not enough to get the padlock and the bolt.<\/li>\n<\/ol>\n
