(pictures are taken from http://nadnadnad.fotopages.com/?&page=2)


Those photos are taken from my friend's website. I'm amazed with how she edited the photos. I'm trying hundreds time to edit my own photos but never succeed. But today, i get the opportunity to learn how to edit photos during the lecture given by Pn Foziah. I love to learn more about photo editing. Now, i'm starting to explore and search for the softwares that could help me in the editing process. The 'editing' skill is very crucial since it can help me in producing good teaching aids in future.
