    Of course, if you mean for out in the field, I can't help you.

    The Rodenstock pocket Depth of Field and Scheimpflug calculator works with any format to 8x10 and any focal length lens at virtually any magnification ratio. Fits your shirt pocket.

    I can confirm Bob's suggestions - the Rodenstock calculator is really useful if you prefer a methodic, analytical approach - and for a beginner, the results cal culated referring depth of field or amounts of standart angles for Scheimpflug a pplications can be quite instructive (or surprising ! Please note that your camera should have precise scales for extension as well as swing and tilt if you want to employ the calculator to its fullest potential. A small ruler for measuring image distances on the groundglass eases the use of t he Rodenstock tool further.

    Bob Wheeler's Vade Mecum running on your PDA is, in my opinion, the most veratile solution. Depth of focus, tilt calculations, bellows factor, etc. all in your hand.
