psp7 is no way as big as sHop but does provide an alternative.
If u come from shop its sooooo limited with standard features u would find in Ps 4 +.
the ability to add shop filters is a goody.
Not all of them run properly which is a shame.
It has bad cropping and selection features
It doesnt perform well if u have a print document as compared to photoshop.
Lighting is also limited in comparison as well as managing paths and vector images.
still its a good budget alternative if u want to spend money on something when there are just as good applications for free that have the same abilities that psp has.
I tried psp 4 5 7 and this is what I can relate from my exposure to shop and painter and other higher end packages.
give zonerdraw3 pixia and canvas6(not 3dcanvas)
heads up peeps there free.
