So ... I often download bokeh, but I'm not always able to see who is the author. In Photoshop I just use the correct texture, but only when I upload my pic on deviantART I try to find texture's author.
I apologize to the authors of textures if I haven't link them yet.
I hope for your understanding!
p.s. sorry, I speak English a bit, so there's a lot of mistakes in this message ><"
