Focus+

For many photographers the passing of the days when all lenses had depth of field scales is lamented. There are, of course, books of DOF tables available and also pocket slide rules. But, if you own a Palm there is now a wonderful alternative calledFocus+.

This program is extremely simple to use yet offers tremendous flexibility. You are able to create a database of all of the lenses that you own and use and also to pre-set theCircle of Confusion(degree of un-sharpness) preferred for each lens or format.

The program offers several different modes of operation. TheHyperfocalscreen shows three columns; The left-most column shows the aperture, the middle column the nearest point that will be in focus and the rightmost column the hyperfocal distance to set on your lens so that everything from the near point to infinity is in focus at that given aperture.

User settings on this screen include the lens used (selectable from a table), the Circle of Confusion desired (if different from what you establish in the lens database) and whether to show distances for full, half or third stops.

ADepth of Fieldscreen shows near and far points at any aperture and focus distance, and has all of the settable variables described above.

Finally, theCalculatescreen is useful if you have the near and far points that you want in focus. When these are entered it shows you to point of optimum focus and aperture needed.

Focus+can be downloaded from several Palm sites includingBitwareand can be evaluated without charge for 14 days. If you decide to keep it you can register on-line for $17.95 and receive a password that allows continued use of the program.

If you own a PalmPilot and are serious about photography I can’t think of a more useful software product product to enhance your technical versatility.

Moon Phase & SOL II

I usually plan my photographic trips to coincide with a full moon. The few days each month around a full moon it rises and sets just before and just after sunrise and sunset, offering numerous opportunities for some striking images.

While there are several good PC programs for determining these times a very handy program for the Pilot isMoon Phase. Combined withSOL IIyou are able to quickly establish the phase of the moon for any date as well as the exact times of the moon’s and the sun’s rise and set for any location. 

SOL IIis shareware and costs $9.95 to register whileMoon Phaseis freeware and may be downloaded without charge.

I wouldn’t be without either of these programs when working on location. In fact, if you don’t already own a Palm Computer these three programs are probably enough reason to purchase one.
