If you are on Adobe Photoshop, you might do the paint over first. Paint the image and then save it to a file type that you would like to save it. For this guide, I am using a TIFF image, which I will save to my computer with Photoshop.
Step 5. Download SketchUp
You can download SketchUp for free here, and from Google Play for $12.98. While you are in SketchUp, import the TIFF image that you just imported to any image editing program and click on “File…”
Step 6. Create a new TIFF (TIF) File
To start, click on “File” and select the TIFF image.
Now click on “File” again but this time choose the TIFF filesize you would like to use for your file. If you are on a PC, it’s usually 512×512 or 2048×2048, so your file size might be less than that size.
Click “File” again and you will be back where you were before you clicked on “Create a File”.
Step 7. Place a layer mask over the image
We also just want to place our layer mask over our image so that we are not going to blend it out. Select all of the layers and open the “Create a New Layer” tool.
At the bottom of the Create New Layer tool, under layers, choose “Layer Mask”. For this, just click on the mask icon on the upper right corner of the tool and your mouse will pop out for you to select a mask. You have to leave the mask on the image as opposed to adding it manually because it doesn’t really do anything else for you. Now go to the “Layer Properties” and click on Blending.
In the upper right corner, on the “Blend” tab, select “Stipple”.
Finally, go to the bottom of the list under “Blends” and choose “Stipple”
Step 8. Set Blending Mode
Go to the drop down menus of your layer mask to select either “Lighten” or “Darken”. I like to use the “Albedo” blend mode
Save your new layer and then press Cmd+A, which in this case would mean “OK”. Your layer will be masked and you will see the mask in the lower right box (you may see that nothing shows up). Now, click on each of
