If you are like me, you have used more than one digital camera since switching from film. If you are even more like me you are using more than one at a time. I have a DSLR but also use a point and shoot when I don't want to haul the big rig around. I also use flickr to organize my thousands of photos (actually they are organized on a big external hard drive, but I use flickr as a cloud based index). I've been looking for a way to search my own photos by camera for a while now. I found this, which I had to access through archive.org:
As I look to organise and tag my Flickr images more orderly i’ve been looking for a way to search for photos I shot using different cameras. Using advanced search doesnt give a camera option but I found a way.
Via this post I found that you can search for images from certain cameras so I yanked the search term from the URL and applied it to a search URL that included my user id. It worked so I need to write this down for reference.
Examples:
Searching for all photos of orchids taken with an N82 yields this search URL.
http://www.flickr.com/search/?q=orchid&cm=nokia%2Fn82
You can see the section “&cm=nokia%2Fn82″ take note of that.
Now a search for orchids from my photos. Note: The 12345678 is not my user ID. I’ve changed it. You’ll see yours when you do your own search.
http://www.flickr.com/search/?q=orchid&w=12345678%40N00
Now you have your user id, put it together with the camera field in a new URL so:
http://www.flickr.com/search/?w=12345678%40N00&cm=nokia%2Fn82
Trala! You’ll find all images taken with an N82. Obviously you’ll need to replace the camera ID. All camera IDs are listed here.

Have fun.
