ExposurePlot (former FocalPlot) is a new free utility that analyzes your usage of the focal length of your lenses (jpeg only), show charts for ISO, aperture and shutterspeed.

Great to determine which lens you 'really' need, or which lens did you actually use on the trip to the mountains.

With this new filter you can read EXIF info from camera, make and or model, just add a string to the filter text fields.

The program can search through subdirectories as well.
