Bokeh

As I mentioned earlier, on the subject of Bokeh, I have read a lot about the Canon EF 50mm f/1.8. There are some pretty good examples of bad bokeh out there too. The problem arises when you have bright lights in the background. But with a normal background I quite like the bokeh produced.

Here are some examples,

1/30, f/2.8 @ ISO 200.
This two shiny pentagons are the effect of a shiny chocolate wrapper on the table. At f/2.8 they actually look like pentagons because of the 5 blade diaphragm of the lens.




1/60, f/1.8 @ ISO 200

This image shows the difference between the wide open aperture and the previous sample. The shiny spots are now blurred ovals rather than pentagons.



Problem with these pictures is, along with distracting backgrounds, the subject itself is glass which means you are not at it as much as looking through it.

On the other hand, here's an example of a better subject over a not very distracting background.

1/125, f3.2 @ ISO 200



Well, that's all for now. I am eagerly waiting for the weekend office outing. Will present some great portrait opportunities I guess.
