JD: cheers - didn't think of bracketing. Exposure timer is a good idea. Colour meter... am pondering that for screen-calibration purposes but I don't think the phone will have the accuracy, though I'll look into it. DOF calculators are already free on the app store, though I don't think any of them will do the adjustments necessary when using tilt - might build that into an LF calculator later.
Good on you for spending your time in such a productive manner. I've spent a bunch of time over the last few days looking for aps that will help ease me into lf. Just downloaded photobuddy which seems to have at least a few useful features but their sister program, a light meter, only works with the 3gs. So, my request for the app is that it be fully functional, ar at least that there be a version that operates on the older 3G phone.
Yeah it'd have to work with 3G as that is what I have There might be a hardware limitation or something though as the 3GS camera is a lot better than the 3G one. Might be that there is no exposure information (EXIF type stuff) from the older camera so no way to meter. We'll see.
MattKing: did you have any particular neg/slide/print archiving software in mind? And what purpose the calendar/contact integration?
With respect to your first question, just something easily accessible and flexible. Others will have a much better knowledge of what might be available than I do. What I do care about is that you don't want two, incompatible systems that require duplicated data entry, different modes of data entry, and duplicate and/or inconsistent searches
With respect to the calendar/contact integration question, I bring it up because photographs often correspond with schedules and people, so it is really irritating to have to store information about times and dates and people that relate to photographs in a different location and in a different way than the information you store about other, non-photographic times and dates and people.
