How to check shutter count using exiftool11/10/2023 ![]() I'm up to over 25,000 on my D200 and D70 today. The very first shot I made with my D200 is #0. I checked: the very first shot I made made with my D80 is #1. ![]() Nikon hides the number of shutter actuations inside every JPEG file made with my Nikon D80, D200, and D70. Helps me publish this site when you get yours from those links, too. Also, complex digital-only lenses make use of the WarpRectangular opcodes, and these vary in strange ways.Get my goodies at Ritz, Amazon and Adorama. There are lots of MakerNotes, which this tool doesn't try very hard to explore. I'm using Adobe's dng_validate to extract metadata from current release 4.0 DNG files. As with the M8, Leica didn't prioritize getting all the metadata right in the SL as high as operational bugs, so it took a few firmware releases before some serious bugs in legacy R lens profiles were fixed. I wouldn't expect the CL and SL to have many unpleasant surprises. Especially since early users could see things that Leica and the first reviewers hadn't caught yet. Figuring out what worked in the M8 was fun. I took delivery of a CL yesterday, so I plan to have a look into the metadata in its and the SL's files over time. Looking at the example above it is likely comprised of several parts that are concatenated into a string that is stored. ![]() I haven't done any research into metadata since I wrote the paper on the M8, but from a developer's perspective using a calculated checksum (something like an MD5 or a SHA256) of the image or parts of it makes more sense as it truly represents a unique ID. With the M240 the count is less accurate as video was introduced and the shuttercount is no longer used in the exif value. I seem to recall the M9 used the same method for generating the ID. However, it was not necessarily accurate as the number was not reset to zero after a shutter replacement. In the M8 the developers just picket an available value that changed for each image It became known as the shutter count as we showed it increased by one for each frame shot. ![]() ![]() The uniqueid is supposed to represent a unique identifier for a single image. ![]()
