If no tags are specified, then all writable tags are copied. This option is very simple, yet very powerful. Depending on the formats of the source and destination files, some of tags read may not be valid in the destination file, in which case they aren't written. This option may also be used to transfer information between different tags within a single image or between different images.
See the -tagsFromFile option in the application documentation for more details. This may be a security problem if ExifTool is executed from another application that blindly passes untrusted file names on the command line since they may be interpreted as ExifTool options if they begin with a dash.
One way to accomplish this is to prefix input file names with a known directory name, eg. ExifTool has a time shift feature that makes it easy to apply a batch fix to the timestamps of the images eg.
Say for example that your camera clock was reset to when you put in a new battery at Then all of the pictures you took subsequently have timestamps that are wrong by 5 years, 10 months, 2 days, 10 hours and 48 minutes.
To fix this, put all of the images in the same directory " DIR " and run exiftool:. The example above changes only the DateTimeOriginal tag, but any writable date or time tag can be shifted, and multiple tags may be written with a single command line. For convenience, a Shortcut tag called AllDates has been defined to represent these three tags. So, for example, if you forgot to set your camera clock back 1 hour at the end of daylight savings time in the fall, you can fix the images with:.
See Image::ExifTool::Shift. Or a new directory can be specified by setting the value of the Directory tag. There is a significant overhead in loading ExifTool, so performance may be greatly improved by taking advantage of ExifTool's batch processing capabilities the ability to process multiple files or entire directories with a single command to reduce the number of executed commands when performing complex operations or processing multiple files.
It has also been observed that the loading time of ExifTool for Windows increases significantly when Windows Defender is active. Disabling Windows Defender may speed things up significantly. The processing speed of ExifTool can be improved when extracting information by reducing the amount of work that it must do.
Decrease the number of extracted tags by specifying them individually -TAG or by group -GROUP:all , and disable the composite tags -e and the print conversions -n if these features aren't required.
Note that the exclude options -x or --TAG are not very efficient, and may have a negative impact on performance if a large number of tags are excluded individually. The exception is XMP groups, which are bypassed in processing so they are never even extracted -- specifying --XMP-crs:all and -XMP-crd:all may speed processing significantly by avoiding processing of bulky Adobe image-editing information.
The -fast option can significantly increase speed when extracting information from JPEG images which are piped across a slow network connection. However, with this option any information in a JPEG trailer is not extracted. For more substantial speed benefits, -fast2 may be used to also avoid extracting MakerNote information if this is not required, or -fast4 if only pseudo System tags are required.
When writing, avoid copying tags with -tagsFromFile or using the -if or -fileOrder option because these will add the extra step of extracting tags from the file. Without these the write operation is accomplished with a single pass of each file.
The " exiftool " script provides a command-line interface to the Image::ExifTool Perl library module which is part of the ExifTool distribution. The Image::ExifTool module can be used in any Perl script to provide easy access to meta information. Here is an example of a very simple script that uses Image::ExifTool to print out all recognized meta information in a file:. The simple script above does not handle this case. There is still much unknown information in the maker notes for many camera models.
To see this information, run exiftool with the -U option. In this area, ExifTool is very much a collaborative effort, and development relies heavily on the input from camera owners to help decode new meta information.
If you manage to figure out what any of it means, send me an e-mail philharvey66 at gmail. Many thanks to all who have helped so far Tag definition column Here you define tags as recognized by ExifTool.
And if needed, you can also add character at the end of tag name -this will force displaying numerical tag value try with -exif:Orientation to see the difference. Of course, only single tag can be defined per line. Hint text column Text entered here is your short "private" help, which will be displayed in GUI's status bar when you start modifying tag value: I hope you can recognize the power of Workspace manager : YOU define any metadata tag you wish to change regulary.
For whatever reason, you might wish to save your current Workspace content -to create a backup of your Workspace, so to speak. And when needed, you just load previously saved Workspace definition file again. When you choose Save , you'll be asked where to save the file and you'll need to set the filename. However, if you're not sure what you're doing, then you better uncheck this option. Preserve Date modified of files -no matter what I think about this, some prefer having this option checked.
Ignore minor errors in metadata -by default, this option is unchecked. That is, ExifTool will refuse to write into file in case metadata is not in "perfect" condition, or if there's a danger that you might lose some metadata by modifying it. If this option is checked and metadata only contain "minor" errors or only "minor" damage can occur , then ExifTool will do his job anyway.
Show Exif:GPS in decimal notation -checked by default because i. GoogleMap uses this notation as well. Show sorted tags not in Workspace -if this option is unchecked default , then metadata tags are shown sorted as defined internally in metadata. Many times however, it's quite hard to find particular tag in listing, so I can imagine, that this option will be checked most of the time.
Obviously, this setting has no influence on Workspace view output see Workspace manager above. Show Composite tags in view ALL Composite tags aren't "real" tags their values are calculated from various existing tags , so they are shown optionally. Don't show duplicated tags It can happen that the same tag is defined more than once inside image file and by default, GUI will show all of them.
If you don't like this behaviour, then check this option, but warning : some other tags might also not be shown! Remaining options settings however, are only temporary as long GUI is running and are not checked by default: Show tag values as numbers Prefix tag names with ID number Group tag names by instance -g4 -this can help you to identify duplicated tags when viewing in Metadata panel.
So, try and see what suits your needs. Copy metadata from single file This will copy metadata from single source file can be MIE file too into currently selected files. That is, all selected files will be populated with the same metadata. MIE file. If multiple files are selected, then metatada will be imported only where source and target files have equal names.
Now you select the menu and, no matter how many destination files you've selected previously, you'll be asked to choose only one source file see 2nd scenario. To put it simple: it's just copying all metadata between files which have equal filename but can have different extension.
Note: Because it's assumed, that destination file has been modified inbetween resized, etc. The difference is: No matter how many destination files you select you must select at least one for menu to be enabled , metadata will always be copied into all JPG or TIF but not both files inside current folder.
After you choose this menu option, you'll be first asked " should files in subfolders also be processed? If we choose No , then again, this option behaves the same way as if all files are selected in Scenario 2 above. Let's see an example, where we wish to update jpg files with metadata from raw files: 1.
Click on Yes button when asked 4. Note: You only need to select one file to specify file extension. Dir2 folder. Step 1: Select log file of your GPS device. As usually in GUI, you must select files you wish to geotag, first. In most cases, folder content will contain series of "session" photos, so you will select all of them. Step 2: Check use all log files in directory if more than one log file for set of files exist.
Let's say you've made three day trip to Venice. In such case all photos will reside in single folder, but three or more log files will exist for that set of photos.
Note: In this case, it doesn't matter which of multiple log file you choose -important is, all log files must have the same extension. Step 3: Choose Reference DateTime value. Here you define which photo DateTime values to compare with those in log file. Step 4: Choose if TimeZone offset is needed to be taken into account. This is funny one The thing is, log files contain UTC time, while camera is usually set to local time of where photo is taken.
In most cases, we are dealing with two scenarios: Case A: Photos are taken in your local time area -in this case there's no need to use TimeZone offset option.
Case B: Photos are taken somewhere outside your local TimeZone area -in this case you must use TimeZone offset option. In both cases above it's assumed, that camera is set to local time of where photos are taken. Note: It is expected that image and sidecar files only differ in extension -name part however, must be equal. Example of valid image-sidecar file pair is: MyPhoto.
Because image and sidecar files usually reside in the same folder that is, they are mixed , it is a good idea to use file type filter which is set to "Show ALL files" by default. However, this setting is not required! Workflow is as follows: Sort files by file extension so, for example, JPG and XMP files are grouped -not mixed or use desired file type filter i.
The only reason for doing this is: you can select only image files easier. Select all image files you wish to modify. After choosing menu Import GPS data from xmp file s , you'll be prompted to select folder containing xmp sidecar files -in most cases, that will be the same folder where image files reside.
Extract preview image from selected: raw files As known, every raw image file also contains JPG image, which serves for previewing raw image file content. In most cases, this JPG image is "as if photo would be taken in JPG mode" -while this is true for exposure and colors, resolution pixel size may differ depends on camera.
Right click on an info, then select Modify option from the context menu. In this way, you can edit all or selected EXIF data of images easily.
Note: It can be used for EXIF editing, but some of the options are not enabled in unregistered version. You need to pay to get a registered version. These options let you edit focal length of camera, date and time of image captured, and some other EXIF data. You just have to browse an image folder, select image, and edit them using these options. Here you can preview selected image with its detailed EXIF data. Picasa is a free software to edit photo metadata. It is a very popular Image Browser and Image Editor.
First, you have to select an image to edit its EXIF data. Since it automatically adds all images of computer to library, you can easily select an image. You can edit images, add text, add filters, set brightness, set contrast, set colors, add watermarks, save image as JPEG image, batch image edit, create collage , play slideshow, etc.
It supports most of the image formats and convert them to JPEG formats. ImBatch is a free and popular image browsing and batch image editing software.
You just have to add folder of images and select one of them to edit. This option will direct you to a new window with all EXIF data and you can edit them one by one. First, choose image or folder containing images.
