Metadata is any information about an image, or any other media, that is present, but not immediately seen. Some of this data describes the photo and cannot be changed, while other information can be added or altered.http://www.youtube.com/watch?v=cex9tBeBDJM Metadata is a tool in Photogene for the iPad, a graphics editing program that allows you to crop, rotate, retouch, adjust and manipulate images.http://itunes.apple.com/us/app/photogene-for-ipad/id363448251?mt=8# 

The iPad is a portable computing tablet developed and manufactured by Apple that lets users perform a variety of functions, including browse photos, watch videos, play games and read digital books.http://www.apple.com/ipad/features/ The device can also connect to the Internet through WiFi or a data network and can quickly access email, websites and music downloads.http://www.apple.com/ipad/features/safari.html The Galaxy Tab by Samsung is a comparable device that supports Microsoft software.http://www.samsung.com/us/mobile/galaxy-tab/SPH-P100ZKASPR-features

First, you need to open the Photogene app and select an image you would like to edit. When you get to the main editing page, locate the the "Metadata" button at the top-right corner of your screen. Tap it to activate the metadata menu. The menu has three tabs: "General", "Exif" and "IPTC".http://www.youtube.com/watch?v=cex9tBeBDJM

The "General" tab holds all of the description information about your image, such as color model, DPI (dots per inch), depth, file size and dimensions. "Exif" stands for "Exchangeable Image File Format" and is used by digital cameras and scanners. It contains the same kind of information as the "General" tab, but is used for cameras instead of computers. Look these tabs over for a minute or two.http://www.youtube.com/watch?v=cex9tBeBDJM

The last tab, "IPTC", stands for "International Press Telecommunications Counsel". This consortium of the world's major news agencies was developed to safeguard the original works and interests of the world press.http://www.iptc.org/site/Home/About/ For your purposes, this tab is simply an area where you can enter personal information about a specific image. Some of the fields include "Author", "Title", "Caption", "Date Created", "Location" and more. Try adding some data of your own to help personalize the image.http://www.youtube.com/watch?v=cex9tBeBDJM
