[ quick howto: Lightroom 1 & 2 (and 3) databases are in sqlite3 format, which means that freely-available tools can extract data from them. I use sqlite3, some shell scripting, and R (and occasionally excel) to produce summaries of that data. Why? Data offers some insight into the kinds of photos I take. Mostly, though, it’s fun. I’d be happy to expand on the actual code that goes into these plots, if there’s interest. ]
Below is a set of plots that summarize some of this year’s data. Click through to flickr to see the larger version.
What’s interesting this year? Well, crop ratios looked pretty similar to last year, so this year, for the first time (suggested in a post by Keitha, whose photos I admire tremendously, and whose Pentax lens set I envy with the fire of a million anti-glare-coated nine-aperture-bladed all-metal suns) I pulled out some information about aperture for each of the prime lenses that I shoot with. You can see these four frequency plots (for each of the Pentax DA 70mm F2.4 ltd, FA 50mm F1.4, FA 35mm F2.0 and DA 21mm F3.2 ltd lenses) in the left hand column of the image. Right off the bat you can see that I shot a lot with the FA 35mm this year (which is confirmed by the “overall lens use” plot on the right column). In fact, I took that lens along as my sole lens on a few long weekend trips to Ventura, CA, and the San Juan Islands, and really loved its performance. It does great at large apertures, but I also used it a lot for street shooting at f/8 and smaller apertures.
Runner-up in frequency this year is the FA 50mm F/1.4, which ordinarily I would say is my favorite lens (and it very much still is; it just wasn’t as convenient a focal length to take as my only lens on those vacations). Its sweet spot [where it’s sharpest but still has a nice narrow depth of field] is about F/4, which is where I primarily use it.
Neither the DA 70mm F/2.4 or the DA 21mm F/3.2 got as much use this year, but I really love some of the photos I took with those lenses. In fact, I carried these two lenses specifically for their light weight and trim size on the Flagstaff photowalk I organized in July.
How did 2009 stack up to 2008? In terms of absolute frequency, nearly identical! I kept 1308 frames last year, compared to keeping 1340 in 2008. Far fewer of those are picks, or posted to flickr — though a good number are waiting for me to come back to, to finish workup or to make a print.
And that’s it for the 2009 photo stats! I did re-work my keyword network code, so perhaps can follow up this post with a little more about keyword relationships.

And, as last year, I hope soon to follow up with a report on my 2009 photo goals, and to set a few for 2010.
