How the heck do I achieve this DOF?

That's very well done Mum - cute expression on his face .

I wish I could find a better shot and one at f/4, but here's one I took at 5.6 at 138mm with my 70-200L f/4 on my 30D. I'm sure it's capable of very nice background blur (bokeh)...

Thanks. It was taken forever ago... I'm surprised I can't find any taken at f/4.

Thats a great photo mum!! But I am mainly having trouble getting full body shots, as opposed to head/shoulder shots with this DOF. I think its because you need to step back to get their whole body in the frame, and that results in more DOF. I reckon I need to set my lens to 200 at f4 and see what I come up with.

Oh, I see what you mean...

my lovely wife
70mm f/4.5

If I would have been further back and shot 200mm at f/4 it would have really blown out the background.
