In this instructable I will show the process of turning a black at white image, with watermarks, into a usable vector. I am not promoting theft of imagery or copyrighted images.I claim no ownership or profit from this photo, I am merely using it a tutorial piece for learning purposes.My friend, however, will be getting a necklace made from this vector. (As seen in one of my other Instructables)
I will be using Photoshop for this process. Start by going to 'Image,' than, under 'adjustments.' Choose 'Adjust Brightness and Contrast Levels.'
In this step I only pushed the contrast, and I left the brightness as it is. By doing so, the blacks in the feather engulf the lighter watermarks, leaving only the feather silhouettes after the process. I did this step twice, to ensure that when I vectorize the image, the watermarks would not distort the image.
After uploading your image, select 'Trace Bitmap.'
Although there are alternatives to 'Brightness Cutoff,'but it has worked best for me. People more experienced in Inkscape may prefer to use 'Edge detection' or 'Brightness steps.'
There is often cleaning up to do. Select the 'Edit Path by Nodes' tool button on the left side of the page. The nodes that show up can be manipulated, moved around. If there is a hole in the feather, it will show up as a small, thick, group of nodes amongst the black. Just select them and you can press the 'delete' button on your keyboard.
