On practically all SONY cameras this is the number of times the shutter had to mechanically move in order to produce an image. What does the number of exposures mean?.The webpage design IS copyrighted and direct copying is prohibited (mainly due to scammers). If you spot any problems or issues - please let me know on tool is not copyrighted - see the javascript source if you want to re-use the code. The tool has also been updated again - but only on the outside - to make it more user friendly. I have moved the tool to a new server and domain name. In July 2022 I have discovered that in the meantime my tool appeared on multiple YouTube videos and that certain aspects were found to be lacking. A side benefit is that it is lighting fast (the first version had 10+ second waiting times - which is extremely slow by internet standards).

With that 'breakthrough', the tool can now read the data directly on your computer, thus the data never leaves your computer - making it safe for both me, the author, and you the user.

The documentation provided by Phil Harvey on his website again made this possible. The second version was created in the fall of 2018 and featured a simple EXIF decoding implementation in JavaScript - the 'programming' language that enables most of the fancy stuff on the web. Using the ExifTool application also meant that the files had to be uploaded on one of my servers, which meant that with time more and more problems were being caused by the tool (not to mention all the hacking attempts). (You can read more about it in this thread about the tool) The first tool used the free and opensource application ExifTool by Phil Harvey (Credit to that person!) to extract the required data from SONY ARW and JPG files. The tool was created in april 2013 when a user called Micholand posted a way to read shutter count information on the A900.
