Today is a special day, because it’s the day when I’ve been taking digital photos for half my life. To celebrate the occasion, life has been updated, and also here’s a ton of different photo stats. :D
First off, some numbers (updated from here). I currently have 360,233 photos tagged in Photoshop Organizer.
Here are the dates on which I took each 25,000th photo as well as the number of days between each 25,000th photo.

Here’s updated stats for my two cameras, plus the D50 (for comparison with the shutter counts below):
| Nikon D50 | March 22, 2006 – November 15, 2009 | 1334 days; 3.655 years | 105,067 photos | $570 (+$250 repair cost) | 78.8 photos per day | 0.54¢ per photo (0.78¢ per photo including repair cost) |
| Samsung SL30 | July 27, 2009 – June 13, 2014 | 1782 days; 4.88 years | 20,266 photos | $70 | 13.5 photos per day | 0.345¢ per photo |
| Nikon D90 | February 26, 2010 – June 27, 2014 | 1582 days; 4.33 years | 158,801 photos | $780 | 100.38 photos per day | 0.49¢ per photo |
I found out recently that the EXIF data of photos includes how many shutter releases the camera has made, which is more accurate since I delete many photos I take now. I also found the information for my old D50. Unfortunately my crappy SL30 does not track that data (and the filenames aren’t much help; the first photo is SDC16333.JPG, the most recent is SDC17918.JPG). My Kodak DX6490 also does not store that information (which isn’t entirely unsurprising).
(The D50 seems to store shutter releases as an unsigned 16-bit int, so it wraps around after 65535, so I had to do some maths. The 65535th photo was j4cbo at the Haight-Ashbury Fair on June 8, 2008.)
| Nikon D50 | March 22, 2006 – November 15, 2009 | 1334 days; 3.655 years | 106,916 shutter releases | $570 (+$250 repair cost) | 80.15 shutter releases per day | 0.533¢ per shutter release (0.77¢ per shutter release including repair cost) |
| Nikon D90 | February 26, 2010 – June 27, 2014 | 1582 days; 4.33 years | 197,675 shutter releases | $780 | 124.95 shutter releases per day | 0.39¢ per shutter release |
I guess the lesson there is that I delete many more photos now than I used to. It would have been interesting to have numbers for the SL30, since I feel like I delete a lot of those shots given how many come out crappy.
Costco prints 4×6 prints for 13¢ each. To print all 360,233 photos would cost $46,830.29. Also, at a weight of ~2 ounces per photo, the entire stack would weigh 45,029 pounds, or 22.5 tons.
Also here’s some updated graphs.
Number of photos taken by month, log scale y-axis:

Same thing but with a linear y-axis (second graph only includes time after graduation from CMU):


Total number of photos taken through time (second graph only includes time after graduation from CMU):


And amount of time between 1000 photos (second graph only includes time after graduation from CMU, so it starts at 131,000):
