Today's focus is that area of acceptable focus in a photograph we refer to as depth of field. While the first and easiest to control factor for DoF is our lens' aperture, there are several other elements that factor in:

Lens Focal Length
Apeture (F-Stop)
Distance to Subject
and Circle of Confusion *cue groaning noises*

Large format is known for it's *look", but there's more to it than ridiculously shallow depth of filed and swirly "BOKEH". What if you're trying to capture a landscape with deep depth of field? Fortunately, large format has a few extra tricks to help maximize your camera's DoF potential!
