This is a fairly simple Exposure and Depth of Field calculator I made for Windows Mobile phones. Here is what it can do:
1. Calculate bellows extension factor
2. Calculate exposure based on Zone System
3. Calculate exposure by picking from a manual EV guide (when you have no light meter)
4. Automatically compensate for reciprocity failure based on film type
5. Filter exposure compoensation
6. Calculate near/far depth of field for common film formats
That is the good news- the bad news is I haven't made a GUI editor for editing things like what lenses you own (focal length needed for DOF/Bellows calculations), what films you use (needed for reciprocity failure) and what filters you use (needed for exposure compensation). All of this data is in an XML file that you must edit and put in the same directory where you install the LFBuddy.CAB file. I've attached the XML file that comes in the CAB file- so you can easily take a look at it and edit it. The schema should be pretty self-explanatory.
General operation/installation:
1. Download the CAB file unzip it, put it somewhere on your Windows Mobile Phone/PDA.
2. Execute the CAB file using the File Explorer app on your Windows Phone (hopefully you have one) or through some other method
3. Installation will proceed and will ask if you want to install on the Storage Card or the Main memory etc.
4. After instalation edit the XML file to add your lenses, films, filters etc.. copy it to the same directory where you installed the program.
5. Start the program. The first step is to pick your lens, then pick your film then put in the meter reading of the scene you are photographing.
6. If you want to place the meter reading at a different zone change the zone, if you think bellows exposure compensation will come into play enter the bellows extension.
7. The adjusted exposure will show in Red. You can also go to Corrections and dial in a filter you are using to adjust the exposure further.
8. If you want to calculate DOF- after you dial in an aperture go to More and select DOF Calculator and put in your focused distance. It will give you near/far DOF.
That's pretty much it. Hopefully someone on this list uses Windows Mobile and will find this useful.
