33 filters effect in prisma free. Easy and Simple to convert a picture to an art photo and digital skecth. By using photoshop you always use redfield fractalius to make it like digital skecth and it took a time and need to blend layers by layers. but, this app can make you shock. Its simple and faster then photoshop. If you really want to try out some filters on your photos, the quality provided by this free app is great. I only wish it could use wider shots, but if I really want to touch stuff up like that I'd probably move my photos to Photoshop. Enjoy it.
