statistics, don't we love them all?

I finally decided to work a little bit with the statistic programm R again, and thought what could I analyse. So I decided to analyse which focal length I use the most with my D50 and was quite surprised by the result.

But first where to get the data from? In modern time like today your camera saves tons of informations in the jpeg files, so called EXIF informations.

what todo to get these data?

1. write a small script in python which reads the exif informations from all you files on the harddisk

2. stores this result in a txt file as matrix

3. start R import the data and do some statistics

After I saw this result it pointed me that my future plans to buy lenses are quite easy,

arround 300 mm prism lens -> not affordable
arround 100 mm prism lens for macro -> affordable from sigma with 2.8

and I'm still dreaming from a ultra wide angle for landscape fotographie, maybe in a year...

( proud of me that I refused the offer to sell my camera to a friend and get a D80! Just saved 500$...) Posted by Picasa
