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. So what really limits the life of a modern camers? It seems like these days mostly it is relative position in relation to other released technology.The tool was created in april 2013 when a user called Micholand posted a way to read shutter count information on the A900. The M9 had that time and humidity based sensor corrosion problem but will the T's sensor fail like that?.Which will mostly age slowly due to storing metadata for the camera and firmware updates. Of course if you use a SD card that will wear instead of the camera's internal flash storage. I'm sure that these fail occasionally but I've never heard of it. microswitches that activate buttons like the shutter release and control wheels.The battery but that is easily replaced.For me at about 1500 shots/month on this camera that would be about 5.5 years. shutter - let's assume something like 100,000 frames which is half of their expected lifespan on the SL.Of course shutters do wear out eventually but they are just one assembly which can be replaced when the camera is serviced. One thing that might be worth considering with modern digital cameras is shutter count really a good proxy for age? In the film days when you took a picture the film had to advance which slightly wore the film transfer mechanisms as well as the shutter. I haven't cracked the whole code yet but it looks algorithmic to me not something that is based on a random number generator or anything like that. So several shots taken very close to each other in time have unique id's that are close to each other in encoding. When I look at the hexadecimals, there is part of it which seems to identify the camera and there is part of it which seems to be correlated with the time that the image was created. I've been playing with exiftool poking at my files and from what I can tell the some sort of time based encoding is used and it doesn't contain the shutter count. I believe that if it it existed it was going to be part of what is encoded "Raw Data Unique ID".
