Digipak- Software?

We have decided to use Photoshop to make the digipak, this is because this software will give us the best looking graphics possible, and this is important to make sure that our digipak fits in with the digipaks already out there representing the rock genre, and good, professional looking graphics are a big part of that. 

Using a program like Microsoft Publisher could have looked ok, but it will not look as professional as something that is created in Photoshop. 
The mac computers that we use in lessons do not have Microsoft publisher on them, so this would mean that if we did decide to use Publisher, we would have to do all of the work outside of lessons and this would also mean that we could not compare and deliberate on ideas and see what looks best. This could mean that all of the panes on the digipak look different or the colours are slightly off, and we wouldn't realise until they were all put together.
