Footwear Photoshop Rendering Tutorial > parts 1-6
To start with, make a sketch of the shoe to use as an underlay. The more in proportion and accurate this sketch is, the easier it is to do the required line art which will be used as a template for the rendering.
Using illustrator, place the scanned sketch in a layer and dim the image (under layer > properties). Then using the pen tool, draw over the image, making frequent use of the pathfinder (cut, intersect shape areas, add to shape areas) tools.
Then cut and pasted into photoshop. Cut and paste the same artwork twice. Once as a Path, and once as pixels. The paths are used as cutting paths and masks for the rendering, and the pixels just give a good quick easy overlay/underlay to the rendering so you can see whats going on.
From the path palette, you can select different parts of your work path ( rename to “All”, or something like that). Once you have the part you want ( start with outline shape that is the whole upper), you can cut and paste that path to create a new path (renamed Body).
This path can then be selected, and you can make a new layer to start painting into. Keep layers and paths well organized and named (instead of “Layer 38”), so its easy to find them later. By the end of the rendering it’s typical to end up with something like 30 paths and 60 layers, so having some meaningful name helps a lot.
