Almost all digital cameras save JPEG (.jpg) files with EXIF (Exchangeable Image File) data. Camera settings and scene information are recorded by the camera into the image file. Examples of stored information are shutter speed, date and time a photo was taken, focal length, exposure compensation, metering pattern and if a flash was used.
Use the data as a learning tool
Many camera owners study EXIF to compare successful photos to those that are not. Data provides insight about how camera settings affect photo characteristics such as exposure, depth-of-field and subject movement.
Other file formats supporting EXIF
EXIF is read by applications that support JPEG and RAW and TIFF files. They include web browsers, image editing and organizing programs and some printer drivers. The printer drivers use the information to automatically enhance images, which can result in a better looking prints.
Preserving EXIF data
If a copy of an original image is edited and then Saved correctly, it will preserve the same data embedded in the original file. Check the manual of your photo editing software for specifics about preserving EXIF information during the editing process.
Viewing EXIF data at photo hosting sites
The information can be viewed online at photo hosting sites. It is often visible under, or to one, side of a photo on display. Or there will be a link or icon near the image. Click on it to reveal the EXIF data.
Different photo hosting sites may use terms other than EXIF. For example, Flickr uses the word properties instead of EXIF; Picasa web albums have an area called Photo information; click on the More Information link to see additional photo EXIF data.
Using browser EXIF viewers
Another way to access EXIF data when viewing photo online is to use an EXIF viewer that is compatible with your browser. Some freeware EXIF viewers are listed here, along with other useful free software for the digital darkroom.
Once the EXIF viewer is installed in your browser, right-click an image and then click the link for the EXIF information in the drop down menu. A window will open revealing available EXIF.
TRES BIEN!
Thanks for info.

Como faço para não aparecer o exif , quando posto uma foto?
alire, one of the ways to see the EXIF data when viewing a photo online is to use an EXIF viewer. I personally use Opanda Iexif. It’s FREE. Once th program installed, you simply right-click on an image that is posted on the web, click the iExif menu and a window will open to reveal available EXIF information. It’s important to note that if a person doesn’t Save a copy of an image correctly, EXIF data will not appear in the new file. Here’s information about how to save EXIF data when editing images.
i own a sony cybershot DSC 110.I want to know that how can i adjust my camera’s DPI(Dots Per Inch) manualy.currently its on 72,however i want to increase it for a clear resolution.Please help.
You can change the dpi with photo editing software, not in the camera. In the camera, you can only change the resolution.
Is it possible to print a photo with the Exif information showing as well? (I use Picassa)
Thank you
Yes, select an image or images and click the Print Button. Then press the Border and Text Options button. A Printing Options window opens. Click the Boarder and Text Options button > Select the radial button for EXIF information.
In this window, you can also do additional things such as add a border, change the font type and size, and select if the EXIF info is printed below or on the image. The preview window shows you what the print will look like.
You can also do this if you print contact sheets of photos. Album > Print Contact Sheet.
Thank you very much – I will try it.
Hi Gail, I’ve tried that and although it works it doesn’t put the information I want on or below the image. The main Exif info I would like is the date and time (if possible). Can that be done?
Thank you.
bardzo dzi?kuje! (Thank you very much!)
You’re very welcome Daniel!
thank you for that article. (EXchangeable Image Format) Extensions to image file formats that hold the camera settings used to take the picture. Developed in 1995 by JEIDA for JPEG images, EXIF data was added to TIFF, RAW and other formats later. Most digital cameras support EXIF and save the data in the file headers. However, when an image is edited, the EXIF data may be automatically removed by the software. An EXIF reader is a utility that is used to read, display and save EXIF data from a file. [Source].
You can download EXIF READER from here for free.

Is the camera (Exif data) reset whenever I keep it without batteries for a long time ?
You won’t lose EXIF information since the data is stored in individual images, not the camera. If you’re not going to use the camera for a long time, it is wise to remove the batteries. You will lose camera settings such as time and date, and any other changes you’ve made. The camera will return to the default factory settings. However, you can change the settings again when you reinsert the batteries.
is there any way to automagically add the exif data for photos already uploaded to my flickr account to the map? i know the proper setting will do so going forward, but i am hoping i can apply the add-to-map to photos already uploaded.
As far as I know, there is no way to add EXIF date after photos have been uploaded. You may want to double check in the Flickr forums.
Was the exif in the photos you uploaded originally? If an image is not saved properly after editing in some programs, the exif may be lost in the saved file (not the original file).
I’m more curious: can you REMOVE such EXIF data? I mean, you can reconstruct an edited image from its original EXIF, after all.
Check your editing software to learn how to Save a jpeg image so the exif information will be removed in the copy. There are also programs that let you edit Exif data, such as EXIFeditor and Opanda PowerExif, to name a few. Here’s a related article about saving EXIF data which will help you understand the saving options in many photo editing programs.
Hi Gail, Please answer this for me.
If EXIF data on a posted picture shows “SOFTWARE” (such as Adobe Photoshop CS4 for Windows os Photoshop Elements etc ) does that indicate that the picture has been modified? If so, is there a way to determine the modification?
Jack, Any time you open and save an image, there is some modification to it. When saved (and edited) correctly, there is little perceptible loss of image quality when compared to the original. Yes, when you save an image using a program like Photoshop, it adds the program name to the EXIF data.
I am not clear At all.
Here are two photographs. I want know about EXIF data and which one edited
http://www.flickr.com/photos/bashir-bd/3734008347/

Go to the main page where your image is displayed. In the right-hand column, under Additional Information click on More Properties to find the EXIF information.
Flickr uses the word Properties instead of EXIF.
