hi everyone

i recently bought the 550d twin lens kit, i am new to the slr industry, although have always loved photohgraphy.

ok, here is my questions.

1. a lot of my pics, are out of focus in more places than they are, eg: when itook a pic of a train, the whole thing was out of focus except for the exact front end of it. which looks good in a way, but not in another, depends on how i feel when i look at it whether i like it or not.

and yet when i take a similar shot, slightly different angle, everything in the imahe is in focus.

how do i get more of the shot in focus.

2. i got a polarising filter, there is an arrow on the rim of it, what is this, and how do i aim it? it is a circular polarizing filter.


well, i think this is about it for now, ill ask more as i need to.

regards.
