on the butterfly and the school with the raven we mostly used the mask tool and lasso to cut out parts we didn't want to see.we also made the pictures fade in the compass one and the school with the raven. for the northwest project we used the gradient to make the mask and make it look cool. the differences i see are its a lot easier to use illustrator then photo shop to me because photo shop if you mess up you can't do undo you have to step back and there is only so many times you can do that. photoshop is also harder to import pictures to and place them. but graphic designers have to use both of them because sometimes you have to make a logo but also use a picture and have to photoshop something out.
