Nikon Shutter Counts, readingOpanda
Opanda offers both armature (free download) and professional version ($) that will allow you to see the shutter count. While we haven it extensively tested this we know that it does work on many Canon models.
Look down the IExif file to line 0093. You will see a number like 18 00059196. The last numbers are the shutter count. You can test this out by releasing the camera and you will see the shutter count change.
"Opanda's site states that IExif 2.3 only supports Nikon's D200/D2H/D2X/D70(s)/D50(s) and later. I just verified this, in part, by checking a .jpg image from a D100 -- no data!. Same holds true for a .jpg from a Sony DSC-F828."
From their web page: Opanda IExif is a professional Exif viewer in Windows / IE / Firefox, From a photographer's eye, It displays the image taken from digital camera and every item of EXIF data in the image from beginning to end.
