As a photography student I'm very familiar with the editing software for pictures such as light room and Photoshop, therefore for the editing of my advert and my Digipak, I decided to use Photoshop CS6 and Photoshop CS5 as they are all very handy and have a huge amount of tools and features which would enables to contribute more creativity into my products.
At home I have purchased Photoshop CS on my macbook, I use it all the time to edit my photos and other things.
At school I use Photoshop CS5 extended to edit my photos and create my products as it's the only photo editing software I can found on the Imac of school.
