If you are a serious photographer, then you'll understand the importance of EXIF files which give you detailed data about the exposure and other aspects of your photos.
Exif Pilot allows you to read the information contained within EXIF photos taken with a digital camera including such things as the date and time the photos was taken, the exposure time, the EXIF version that was used, shutter speed, flash use and even focal length. Using it is as simple as using any file browser such as Explorer - just select a folder with images in the Folders panel, choose some files to use in the files table and you can read all the information you need instantly in the properties panel. If you only want to view those photos with Exif data, then you can always sort photos by clicking on the EXIF column title in the files table and it shuffles them immediately. Unfortunately, previewing your photo is not particularly well taken care of as the preview Window is very small - you may be better to use a third party application to see exactly what your image looks like. What should happen is that by reviewing the EXIF data however, you'll learn under what conditions and focus you are producing your best pictures. Note that in this free version, you can't edit the EXIF data - only view it.
For serious photographers or amateur photographers who seriously want to improve their photo skills, EXIF Pilot Light is a simple but highly useful tool.
