Just a random thought while browsing the photos section - I often wonder what type of camera has been used to take a photo and more importantly what shutter speed and aperture were used.
This is something I've seen on other photography sites while browsing, so I can't claim credit for the brainwave

.
Would this be of interest to people? I guess it might well be as I assume everyone wants to learn and improve their photos.
All of this data could be extracted from the photo EXIF data automatically (for those who leave the data intact - it looks like some people strip the data out, or perhaps their image manipulation programs do) and presented without any extra effort from the uploader.
Might also be worth adding a field for "image manipulation" to mention what sort of photoshopping has been performed, etc.
Any thoughts?
