A digital camera records an image using the EXIF file format (Exchangeable Image File). Most digital cameras support this format. For example, if you have set the camera to record the image in the JPEG format, it actually records an EXIF file (which uses the JPEG compression to compress the photo data within the file).

Image data such as 150, shutter speed, etc is stored directly in the file. The data can be read by any application supporting "JPEG" like Windows picture and fax viewer, Irfan view, etc.

• Just right click on the image file and go to "Properties".

• In the new window that opens up, click on the "Summary" tab. Under that, you will find all the information and the settings pertinent to which snap was taken .
