About:
PDoF is a Depth-of-Field calculator. It is designed to help
photographers to estimate the sharp area of picture.
Installation:
Install PDoF.prc file to your Palm (in Windows double-clicking the
file should do it).
System Requirements:
The program is tested only under PalmOS 3.1.1 but it should work with
every version of PalmOS greater or equal than 2.0.
How To Use:
Just enter all required parameters and hit the Calculate button.
For example, if the film used is 35mm and the camera is focused to 5.0
meters, the focal length is 35 millimeters and aperture is 8 then enter
focal length: 35
aperture: 8
distance: 5
film size: 35mm
and hit the button. The results should be:
near edge of the sharp area: 2.415 meters
far edge of the sharp area: [inf] meters (i.e. infinity)
Feedback:
Please, feel free to send me an e-mail if you like PDoF.
You can also send me feedback, bug reports and comments
about the program. The address is: <mjk@iki.fi>.
History:
Version 0.x
The original code was actually a simple Perl script called pdof (Perl
Depth-of-Field). It is still available at my web site.
Version 1.0
This was the first attempt to make a Palm program. Actually I'm quite
proud of it, because the program was simple, easy to use and it really
worked. This version didn't do much. It only collected the parameters
and outputted the results.
Version 1.1
This version included better floating point output and the infinite
values were expressed better than in previous version. Also, in this
version saving all parameters as preferences was added so they were
available next time, when the program started.
Version 1.2
Current version. The possibility to choose a film size added.
