The trees in my backyard are starting to bloom...and the sky looks kind of freaky. Shot with the nifty.

I would crop the first one a bit tighter.

Another alternative might be to give it a greater depth of focus - the out-of-focus branches and buds are distracting.

The upper left one is. The other I don't feel is as much. Beautiful Bokeh on the first though. :) Soo smooth...

I had the lens wide open. Is there another way of achieving this without resorting to pp?

I'm a big fan of cloud shots. I like that cloud shot. I'm maybe try and give it a bit moore mood in Photoshop by bringing the dark in a bit and maybe a mono conversion would look good.

Yeah if you brought out a little more detail by brightening up the shadow areas a tad in that cloud shot it would be teh sh1t!

Thanks for the feedback guys. I'll do some pp to it later when I get home and see if it helps.

The depth of focus is defined by focal length, f-stop and distance to the target.
One other factor is the size of the circle of confusion, but it is taken for granted that circle of confusion is constant and established by standards while the other parameters above change. Also, for a given prime lens, focal length is a constant.

Therefore, for a given camera and lens:

Changing the distance to the subject and changing the f-stop are the two simplest ways of changing the depth of field.

For a constant f-stop, increasing the distance to the target increases the depth of field.

For a constant distance to the target using a smaller lens opening increases the depth of field.

So, in the case at hand, the conventional method for increasing the depth of field would be to stop down the lens ( for example, change from f/1.8 to f/2.8 or f/4).

Thanks for the explanation Bob. So depth of focus and depth of field are 1 in the same? I had not heard the term, "depth of focus", but am familiar with the principals behind depth of field and how it relates to different aperture settings.

'tis the depth of the field of focus... :-)

Agreed. Or clone them out.

Wait, I think I get it now. So take a few steps back and stop down?

Yes.

BTW, Depth of Focus is different from Depth of field in that it is the range of distance around the focal plane in the camera in which the focus is sharp.

Which term you use is primarily a matter of whether you like to visualize the issue at the focal plane in the camera, or out at the actual subject. The numbers will be different, but the idea is the same.
