Thanks, C. sapidus. I think I'll spare your puny planet, for now.
Is there any way to get that flat, narrow DOF besides using a longer length of focus, such as manipulating aperture and/or shutter speed?
If by "narrow DOF" you mean shallow dof like this:
It's tough to achieve with a small sensor camera. But can easily be done in post using Photoshop. This works best with photos taken at low angles. Here is Sobaaddict's photo:
This is how it looks after one minute in Photoshop:
Open your photo in PS. Click on the layers menu and choose "duplicate layer". In the dialogue box click "ok".
Click on the filters menu and choose "Gaussian Blur". In the dialogue box choose a number between 5 and 20. Click "ok".
Create a mask by clicking on the square icon with the small circle in the middle, at the bottom of the Layers pallet.
Choose the "Gradient Fill tool". Place the pointer at the tip of the piece of fish in the foreground (bottom of image), click and drag a straight line to the top of the image. That's it. If you don't like the effect, just undo and place the pointer in a different spot, click and drag up to the top again.
