Too Much?
As described in the last page, there's more depth-of-field in photography now, due to sensor size.
There's also more depth-of-field because we're using lenses that go only to f/4, instead of f/1.4.
What do you do if you want less depth-of-field?
Solution
Use a 50mm film lens on your digital SLR camera.
The lens becomes about a 75mm lens on most digital SLR cameras.
If you use a 50mm lens that has a lens opening of f/1.4, you'll have three stops less depth-of-field than your zoom lens.
You can blur backgrounds more completely.
In the photograph of the grape leaf, taken at f/1.4, note how only the tip of the leaf is in focus.
Compare how the background looks at f/4 and f/1.4.

When using a wide aperture like f/1.4, focus carefully.
I used a tripod above, because if I moved an inch, the tip of the leaf would have been out-of-focus.
