I came up with a very useful technique for framing a subject that I thought I should share.
If you are using a DSLR, you can shine a laser pointer through the viewfinder. The laser will appear as a dot on the subject in the exact center of the frame. When the subject is in focus, the laser will be focused to a sharp dot on the subject. When out of focus, the dot grows in diameter.
It is a very quick and easy way to approximate framing and focus before making fine adjustments with live-view. It is much quicker and less cumbersome than guessing and checking by adjusting the subject and then checking live view, especially when there is a specific location on the subject that you want to photograph.
I encourage you to try it!

A sighting laser is a big convenience in my workflow as well.
