Garbage Art

(Note: After walking a friend through how to do this, I discovered some errors and omissions - I have tried to remedy that ...)

How do you take this (a photo I took of the sawdust in the garbage can in the garage):

and this:

And make this:

If you care - carry on - if not - you are done!

We start with the sawdust photo and we are going to make a border out of it:


Desaturate it (take out the color):


Set your gradient tool to 'foreground to transparent' with 'Linear Gradient' set. Make sure the foreground color is set to black, and the blending mode (of the gradient tool, not the layer) is set to 'overlay' and draw a linear line through your photo (I started right at the left side and went through about 3/4 of the photo). You should get something like this:
Do it once more to enhance the effect:

Go into Filter - Blur - Motion Blur and put a motion blur on it until it looks like something you like (or not - it all is preparation for the next step ... the Threshold command):

Then you are going to do the Adjustment - Threshold. On the histogram that is active when you select Threshold, slide the slider bar back and forth until you get an 'edge' that you like and hit 'OK'. You will then move it over to the far side to get one side of the border started (this involves free transform - too lengthy to explain ... Photoshop "Help" rocks ...):

Copy it, flip it, move it to the left (again with the free transform ....):


Copy again, rotate 90 degrees and put on the top (with a blending mode of Screen to take out the sharp edges) and do this again for the bottom. VoilĂ  - you have a mask!
But we want borders so we are going to invert it - which I did quickly by just hitting [ctrl] I:

Lay the 'border' file on top of the photo file (you would do this by having both files open in Photoshop and dragging the 'border' file onto the top of the picture you are trying to 'frame'). Resize as necessary using the dreaded 'free transform' so that they are the same size - or frames what you want and then crop off the rest like I did. Change the blending mode to Multiply and this is what you see:


Piece of cake ....
