This is my assignment and tutorial (using GIMP) for the 2 star Visual Assignment, Draw it. I hope you find it helpful!
I used GIMP to transform a photo of my horses into a sketch!
First, open gimp and drag the photo you wish to use into the GIMP screen. Now click “duplicate layer” under the “Layer” tab.
Next go to the “colors” tab and choose “desaturate.” (When the dialogue box pops up choose “lightness” and click “ok”) All color should now be gone!
Like this:
Now click on the “filters” tab ? “edge-detect” ? “edge”
Once you do this, a window will pop up:
You can play around with the Algorithms if you’d like. I chose Prewitt Compass. (They are all about the same) When you choose the algorithm you want click “ok”
Now your screen should look something like this:
Looks creepy I know! But we aren’t done quite yet!
Next, you need to click on the “colors” tab and then “invert”
And you get:
Now if you want to take it a step further and add a little bit of color:
Go to the “Layers-brushes” window…
Now make sure the layer you manipulated is selected and lower the opacity from 100% (I lowered mine to about 70%)
And now we have our final product!
I hope these directions help, Please let me know!
