No, he needs to stop down to a lower "F number". 
"Wider open" and a higher f stop would mean less DoF...
f/x numbers are a ratio so the larger the number after the "/" the larger the hole (or aperture) and the smaller the DoF. So f/2.8 will be a big hole with less DoF and "wider open" than f/11 which would be a much smaller hole and closed down.

Personally i'm not really a fan of 5 but one and two aren't bad. One especially has that abstract feel to it.
Thanks
I've just been trying various levels of magnification. Getting as close as possible.No, he needs to stop down to a lower "F number".

I took them with the lowest F number I could. F/4.5, when I increase the F number, the DOF increases. A photo of an object at F/4.5 would result in the background being blurred, when I increase the F number, the background comes more in to focus.
No, you decrease the f- number. Remember, it's a ratio, so "1/the aperture" not just the aperture. Bit like 1/2 is bigger than 1/4 (half is bigger than a quarter) so f/2.8 is bigger than f/4.
f/4 makes the aperture (hole in the lens) smaller than an aperture of f/2.8. That smaller hole of f/4 will increase the depth of field but reduce the available light.
Have a read of http://en.wikipedia.org/wiki/Aperture
It is rather confusing at the beginning.

I'm just saying that when I raise the F number on my camera, the DOF increases. I don't quite get it my self, but when I increase the F number, the DOF increases.
Kylew - read this Wikipedia article it will explain everything....

I see where you're getting the idea from*, however... it's wrong...
It's just easier discussing things when you use the correct terminology.
*Most cameras will just have the number as 4.0 etc not 1/4.0 etc.

I'm not disagreeing
I was just saying after what twoblacklines said. It's a higher number, but the higher number equates to a ratio that means a smaller aperture. (I get that bit) Just from looking at the camera, it's represented as a larger number when it just says "F", what that number means is different to the fact that it's a higher number we're all being pedantic now though lol
