To be honest, there are PhotoPlus filters that are free, that do what these programs do!
I have them both, and never use them.
I still think there is room for SERIF to produce a fully featured stand alone 2D/3D Animation Studio, built to a professional level. What we have in DP is alright as a toy.....But I have seen much better, though always at a huge cost.
If Serif ever bring out a decent one at a reasonable price, I would be first in line to buy it.
I downloaded four programs, yesterday, at a cost of $1 each. Two of the programs were PopArtPlus and MontagePlus. I say good riddance to them! Montage is a joke. It takes ages to form anything, and it consumed gobs of memory, considering the size of the program is less than 2 MB.I had to reboot my computer after using it. And the saved photo couldn't even be opened afterward! The PopArt result was so horrible that I deleted the program, too.
I didn't expect much for my $4 and I wasn't disappointed. The PanoramaPlus X4 and AlbumPlus X4 were worth the $4 by themselves. I have several Serif programs, now, and I think they are excellent. The Serif name is better not associated with those two junk programs.
