fStop
Simply, fStop defines lens opening. Diaphram is closing lens
opening as the iris of an organic eye. The default value 8 means
th
the 1/8 of area of lens surface is open and able to let the light in.
Shutter speed
Shutter works like a curtain. It lets the light in coming from the
lens opening through the film and blocks the light by shutting the
film surface in short times. This value defines how many times in
a second it shuts and adjusts exposure.
Diaphram Type
Diapram is a part of aperture which makes the lens opening
narrower. Ideally it should be circular in shape as in the iris.
However, due to mechanical reasons, most of the diaphrams are
polygonal, which means they are made of several blades to
conform a circular opening.

PLAY WITH fStop
Test how fStop affects the view at a constant Shutter Speed and lens diameter.
In this example the parameters are:
Lens 50 mm
Target 45 mm
Shutter 1/30
fStop [2.0 - 8.0]

MAXWELL CAMERA
PLAY WITH Shutter Speed
Test how Shutter Speed affects the view at a constant fStop and lens diameter.
In this example the parameters are:
Lens 50 mm
Target 45 mm
Shutter [1/30 - 1/2]
fStop 8.0
INTERACTIVE CONTENT Click here and drag mouse horizontally to spin Shutter Speed value.
DEPTH OF FIELD
When you put camera target somewhere in your scene, areas that are out of focus typically become unsharp. This is called
Depth Of Field (DOF). Use the Maxwell Camera Target to determine the DOF's focal point. The DOF amount depends on the
fStop value and the lens diameter, so the focal distance dictates the amount of DOF. Decrease the fStop value and/or the lens
diameter for a more exaggerated contrast between areas that are in focus (sharp) and areas that are out of focus (blurred).
INTERACTIVE CONTENT
Click and drag mouse to experiment DOF while keeping exposure intact.

Num. of blades and Blades angle
When you use Polygonal Diaphram, you can set the number of
blades and define the angle between them. Thus, you will be able
to configure most common types of diaphrams like hexagonal or
pantagonal etc. Diaphram shape will mostly affect the seem of
blurred areas out of depth and gives the shap to bokeh artifacts.
Lens
Simply, type of lens on your camera. Usually 35 mm lens is
suitable for common usage. Low diameter lenses will give you
wider field of view with more perspective and high diameter
lenses will give you narrower field of view with less perspective.
Depth of field is also affected by the lens diameter for the same
target distance and fStop inversely.
