We're all generally quite demanding and critical (in a good way) about our photography; after all, that's why we're here in this fantastic forum. A forum whose administrators, in
this post, have politely asked us to write our posts in a style that makes them easy to read.
That generated a lot of discussion, but I think its message was generally accepted and understood to not be too demanding.
Now I'm going to go out on a limb here and ask that we try to resist the trend to write "it's" instead of "its".
1) "Its" is a possessive pronoun, i.e. "I bought a good book.
Its title is 'Understanding Exposure'".
2) "It's" is short for "it is" or "it has", e.g. "
It's a bull.
It's got horns" ("It is a bull. It has got horns")
See
here for more examples.
People always get 2) right, but often get 1) wrong, writing "it's" instead - even native English speakers.
It's pretty basic grammar, so I hope you don't mind this refresher course. I occasionally get it wrong too, especially when typing quickly; I'm not demanding perfection, just that we try a little to get it right.
