Whats that EXIF?

EXIF :
"EXIF stands for Exchangeable Image File Format, and is a standard for storing interchange information in image files, especially those using JPEG compression. Most digital cameras now use the EXIF format. The format is part of the DCF standard created by JEITA to encourage interoperability between imaging devices."

What I understood is that, it is some extra information which can be included with JPEG files. Location is one such information which can be added with the JPEG files and following the EXIF standard we are making it easy enough to be inter operable across wide range of devices.

Simply speaking Geotagging is adding location tags with the photos we click.

I was able to get a GPS lock when I was going to my relatives place from Bandra to Andheri. This was the first time I used GPS while travelling. It followed me all the way on Western Express Highway, though sometimes it strayed to some other places I was having fun wondering about, me connected to satellites :D . I've even taken some snapshots and uploaded using Shozu.

After googling for applications that could geotag pics , Shozu was one of them. Since I already had it installed I didnt search for any other application. But what I found was that Shozu is not actually putting any location information in the JPEG files , instead it just sends the location as a tag. I am only 75% sure of it because I have still got to install some software that could actually read files with EXIF format. One more thing I found out was that Flickr offers Maps too. So you can view your geotagged pics on the Map. I Shozu-ed my geotagged pics to Flickr hoping that these will come up on the Map, but they didn't. Got to figure out why.

But sure EXIF , Geotagging , GPS pretty new things to me and fascinating too. Will find out all about it soon.
