“It's a powerful and logical way of creating effects that's relatively easy to learn by seeing how other effects are built. Creating filters from scratch is time-consuming, but for a wider user group, it's a great way to modify already-created effects.”
“I needed rock textures and instead of the usual day it takes me to make one, I was able to make 20! Again – applause to you all.”
