Most of my photographs have been taken with an 8 mega pixel Nikon camera at a resolution of 300 dpi.
The physical size will generally be 3264 pixels along the longest edge, which equates to 276mm. These images can be identified by an 'n' prefix to the reference number that accompanies each photograph. Some may vary slightly where they have been cropped.
A handful of photographs have been taken with an older 3 mega pixel camera and are also at a resolution of 300 dpi. The physical size of these will generally be 2160 pixels along the longest edge, which equates to 182mm. These images can be identified by a 'k' prefix. Some may vary slightly where they have been cropped.
