Camera settings such as shutter speed, aperture, lens focal length, and camera model are all included in the metadata. Most importantly, EXIF data can help you improve your photographic techniques. With the right software, you can even search for photos taken with a specific lens or camera. Knowing the date, or approximate date, of when you took a photo the EXIF data embedded in the image file, helps you to locate it on your computer. The slow shutter and that the flash fired. The EXIF data on this image shows me two helpful things about how the photo was taken. Having a good understanding of the importance of EXIF data helps you to find photos on your computer’s hard drive. We all like to take lots of photos and many people struggle to delete many of their pictures. EXIF metadata that’s stored with your photos can gets used in many ways.ĮXIF data is an important tool to help you store and retrieve your photos.

But once you know what it is you also need to understand how to use it. Why is EXIF Data Important?Īsking ‘What is EXIF data?’ is a good question. It is part of EXIF data for viewing on the camera’s LCD screen and on operating system file managers. Even when your camera is set to only take RAW images, a thumbnail gets created. Thumbnails are also part of the EXIF your camera creates. If this information is not added to the camera it will not appear on the EXIF. These additions can include timestamps of when the image was manipulated, where you save the photo, and what changes have you make to it.Ĭopyright information gets included so long as this has been input into the digital camera that made the photo. Once you upload a photo to your computer, the EXIF data can be added to. Size, dimensions, file name, and camera settings used to take the photo are all included. If GPS is enabled, this metadata is also included in the EXIF. It also gives you information about the time and date the image was created. Metadata attached to an image tells you what equipment you used to take the photo. I recommend that ThumbsPlus users not use both image comments and IPTC annotations.Young woman dancing outdoors with flowers in her hair. I wrote some notes about annotations, captions, and comments in ThumbsPlus, and also some notes about how the way ThumbsPlus uses these produces some strange behavior in ThumbsPlus. Related findings: ThumbsPlus uses both IPTC Captions and JPEG Comment fields to create its annotations. I did a brief search for other programs that show such metadata, but didn't find one that looked like it would extract all metadata except for the Metadata Extraction Tool, which seemed a bit cumbersome to use and I didn't try it. It shows metadata for JPEG files and TIFF files, but doesn't show metadata for GIF files. I also tried this with BMP files but in that case no comment seemed to get written to the file.Ĭonclusion: IrfanView doesn't show metadata for all file types. So it seems like GIF and PNG files must allow metadata but IrfanView is not showing it. The comments also copy to the ThumbsPlus annotation when I select Options > Preferences > Thumbnails > Automatically copy image comments to database annotations = always and regenerate the thumbnail with F3. If I then open another instance of ThumbsPlus and use the same procedure I can see those comments on the file. However, I can open them in ThumbsPlus, add or edit a comment (double-click to open the file in Thumbs, select Edit > Add Comments or Edit Comments), and resave the file, and if I so it seems to write it to the file. Irfanview shows no metadata on some GIF and PNG files I have. I didn't test everything, but I did find an interesting thing while using GIF files and PNG files. I also tried to write and read metadata from the files using ThumbsPlus. If you open a photo in IrfanView and click Image > Information and you can see IPTC fields, EXIF fields, and Comment fields in JPEG files.

You must download the program and also install the plugins to see file metadata.

IrfanView is a powerful free image viewer that is widely used and respected. I used IrfanView to look at the metadata in some of my image files. I was trying to explore what image filetypes contain metadata. I am not an expert on metadata in files, and this is mostly a note to myself on a problem I found trying to view metadata in some image files.
