10月9日的ShutterLife: Shutter Count应用程序分析

Know your camera's shutter count before you buy or sell: for the Canon, Nikon, Sony, Fujifilm, Pentax, Leica and Ricoh models listed below. Buying a used camera? Ask the seller for a sample photo, open it in ShutterLife and read the shutter count straight from the file before you spend a cent. Selling? Share a PDF report with the reading from your own file. ShutterLife reads the shutter count directly from your camera's image files, no internet, no data upload, no account required. Works on iPhone, iPad, and Mac. HOW IT WORKS Import a photo straight from your photo library or the Files app on iPhone and iPad. ShutterLife reads the file and instantly shows you the shutter count. IMPORTANT: ORIGINAL PHOTO REQUIRED The photo must be the original. When you send a photo, messaging apps like WhatsApp strip out the data your camera writes into it, and the count with it. Ask for it via AirDrop, email (original size), or a cloud service (iCloud, Dropbox, Google Drive). CAREFULLY TESTED ShutterLife was built and tested on real camera files, not on simulations. ShutterLife shows the value your camera wrote into the image file. On the Canon EOS RP and R7 in HDR mode, the app adds the measured difference and marks it. Note: firmware updates or counter resets may affect the value shown. No software can guarantee that a file came from that camera unaltered. If in doubt, compare the serial number in the report with the one on the camera. Manufacturer figures are tested minimum thresholds, not failure forecasts. CHECK BEFORE YOU BUY ShutterLife can only show the shutter count if your camera writes it into the image file. These cannot be read: DSLRs from Canon and Sony (for example the EOS 5D Mark IV), the Sony ZV-E1, smartphones (iPhone/iPad), most compact cameras, and the Leica M series. They don't store the count in the photo. Some mirrorless models from both brands are covered, such as the Canon EOS R6. Only the list below counts: if your model is not on it, we have not tested it. With Nikon, Pentax and Fujifilm it sometimes works anyway; with Canon and Sony, rely on the list only.

Write to us via "Contact Us". With two consecutive original photos we can check whether the count can be read. COUNT AND TESTED THRESHOLD See your shutter count and, next to it, how it relates to the threshold the manufacturer tested for. That threshold is a tested minimum, not a failure forecast: above it the manufacturer stopped testing. The figure appears when a confirmed manufacturer rating exists and the counter really tracks actuations. Fujifilm counters track frames instead, so those models show the count without a percentage. SUPPORTED FILE FORMATS JPG, HEIC, HEIF, HIF, CR2, CR3, NEF, ARW, RAF, PEF, DNG PRIVACY FIRST All processing happens on your device. The app uploads nothing, analyzes nothing, and does not track you. No internet connection required. We only see a photo if you choose to email one to us yourself.
