 After you've taken a light meter reading, you must also compute how much to increase the exposure based on the length of the bellows.  This is called adjusting for the bellows factor and is computed using the following formula:<br />
-::::: Bellows Length
+::::: Bellows Length ² (squared)
 ::::: ------------------------   =   Exposure Increase
-::::: Focal Length<br />
+::::: Focal Length ² (squared) <br />
 The lens focal length is noted on the lens itself.  (Media Loan's Calumet lenses have a six inch focal length.)  Obtain the bellow length by measuring with a ruler from the lens to the film plane.<br />

 You will need to adjust the focus of your image as you compose.  This is done by sliding either the back of the camera or the lens board in front until the image appears sharpest.  To do this, loosen the front and back locking screws, then adjust the focus with either the adjacent focusing knobs or by lifting up the focusing knob release lever and sliding the front or back of the camera along the rail.<br />

-If you move the back of the camera, the lens-subject relationship will remain constant.  If you move the front, lens to subject distance change appreciably.  Final focus is done by moving the back of the camera.<br />

 The reflective quality of the groundglass on the rear of the camera sometimes makes it difficult to see your image to focus it.  If needed, fasten the black focusing cloth in its clips on the back of the camera and drape it over your head and the back of the camera in a tent like fashion.  This will exclude most extraneous light, making the image easier to see. While focusing use a loupe to make sure the image is sharp.<br />

 As with any other lens, the overall depth of field of the view camera lens will be controlled by the size of the aperture: the smaller it is, the greater will be the depth of field.  Select a point approximately one-third of the way into the subject on which to focus.  The resulting area of sharpness will be twice as deep behind the point of focus as in front of it.<br />
