all images of the render that i am making into a black and white brush are resized and look better in their full form


press D


Now we'll begin, your going to want to open the render you want to be a brush

now press ctrl+alt+shift+n and do filter render clouds on the new layer

now move your render layer on top of the clouds (so you can see it in the picture) and change the blending mode to luminosity
now press ctrl+e to merge the layers

get your polygonal lasso tool and set your feather to 20 px and now roughly go around your image it doesn't matter if you get it perfact just go around on the inside of the image then click in the middle and hit select inverse

after you press select inverse press delete (it wont look good) but save it as a brush and just make a white background and brush it on and u will see its pretty cool


(really cool with a good background)

And your done :D

Thanks for reading, please tell me how i did
