Despite the service's recent major update, Flickr doesn't yet offer a way for users to search content based on camera settings. Shutterdial, a website from photographer Tianhe Yang, fills that void by using the Flickr API to offer photo searches using four criteria: subject, focal length, shutter speed and aperture. With this, photographers can search out photos taken with specific settings for inspiration or how-to help.

Shutterdial uses a simple interface with four possible settings. After selecting these settings, clicking 'Make Me a Contact Sheet' will return a selection of photos on Flickr with matching EXIF data. Clicking on a photo will take you to the image on Flickr. Users can also choose a 'random preset' option to see search results of pre-baked combinations of settings. 

According to Yang, during his early photography years he'd wished he'd had 'a way to see how great images could be taken at the various settings' offered by his gear. Fast-forward to more recent times, and says Yang, 'I still think it'd be handy to have such a tool to help with a range of situations that I'm not intimately familiar with.'
