![]() ![]() The most common EXIF fields are shown below:Ä¡err := filepath.Walk(filepathArg, func(path string, info os. The tool focuses on displaying the metaÂdata from Exif images (i.e.jpeg files), but can extract the metaÂdata from almost every common media format including images, videos, audio files, Microsoft Word documents, Adobe PDFs. The utility allows you to choose the fields you like to extract or simply all of them, filling in blanks where it can. Exif Info is a tool that will show you the (normally hidden) metaÂdata that is embedded in a file that you upload. The reason for choosing Go was that I use Windows and Linux but others may use Mac, most togs will use Macs to manage photos and while it's a command line only util I needed a way to use it on any of the major platforms, Go can cross compile, so that's sorted. ![]() You can find the code for my EXIF scanner extractor here: GOExifExtractor on Github The GOExifExtractor Utility From that I was able to put together a suitable struct, read the info from file in a tree and dump the whole damned thing back out to a CSV file that could be loaded into any suitable spreadsheet app. Modern cameras, and mobile phones stores EXIF data and other important information viz- software used for processing, GPS information, make and model of the camera etc. The examples supplied with the library are superb and ready to be built, so I stripped out the requied code and then built myself a file-folder scanner using the filewalk function from the standard library. We need a library that can extract EXIF data from any JPG file and hand it over in a simple text based format. Luckily Go is a best damned language on the planet and I needed a simple Go project to get me started as I was learning Go. We thought Lightroom could be used to get the info but despite it begin one of the best photo image organisers available it's useless at allowing you access to it's internal database, it demands you jump through some severley archais hoops using LUA, I've no wish to learn a dead language from scratch just to get a CSV. We needed the key critical EXIF data into something we could pass to the page designers, so we needed the filename plus the EXIF data, they would then copy and paste it into the 1,000 images in the book's layout. From the below image, you can now notice that weâve got all the information drawn from our image file from the very basic to advance. How the heck do you do that for 1,000+ images that are scattered through sub-folders? The London book I worked on had 12 chapters with 14 locations per chapter, that's around 200+ sub-folders. To extract the entire metadata of a file, we just need to execute the given below command: exiftool .Getting the EXIF from a single image is dead easy, right-click on it select Propeties ( Windows ) or "Get Info" ( Mac ), there it is. When you edit all the info is kept and stored so it can be used to correctly catalogue your images. The books FotoVue produce are for photographers and that means you need to have the key informaiton like location, camera, lens, focal length, aperture, ISO, all that good stuff and one place that's stored is in the EXIF of every image. When I worked on my first photo book for FotoVue I'd shot and edited around 3,000 images files, from those we selected around 1,000 images to go into the book. This is the most basic info, on top of that there are extensions for the IPTC info which has tons more info like keyword trees, descriptions, copyright, all valuable stuff you store and maintain using software like Adobe Lightroom. The EXIF data contains the most critical info needed about an image, the camera, the lens, the focal length, aperture size, time and date of the shot and even the GPS info. Have you ever wondered how when you take photos using your mobilephone and then upload them to your favourite website, how does it know so much about the phote image file? The secret is the EXIF data stored within the JPG images you capture and then upload. What you need is a super fast, efficient language to do the job for you. * Import photos and videos into customized folder structureÄeluxe viewer and photo metadata toolkit for amateur photographers and professionals alike.Using Go to extract EXIF data from Image filesÄ®xtracting EXIF from a single file is easy but suppose you have a huge folder tree with hundreds or thousands of images, what then? Then suppose you have a publishing deadline for a book. ![]() * Support for PTP/MTP transfer, iPhone, iPad * Allows to remove EXIF, IPTC and/or XMP headers from JPG-files * Batch change of capture date/time, works with JPG and RAW formats. * Rename picture files keyed to the date and time as well as other photo information * Edit EXIF and IPTC metadata (full version only), add or delete tags, lossless rotate and update embedded thumbnails, in single file and batch mode File manager and fast viewer with slide show.
