Sketch: 10 min
Rendering: 20 min
A quick demo on a quick technique I am using lately for rough and quick concepts. This technique is great to pop a loose sketch for a design review. This is just one of many quick ways to communicate your ideas to others. The important thing is to find a few ways that work for you that the people you work with can understand.
Step 1: scan, clean up, and set layer to multiply
Step 2: create a new layer, and loosely brush in a medium grey
Step 3: erase out overspray with block eraser
Step 4: select surface facing viewer looselt with polygon laso and use dodge and burn to add form
Step 5: Select surface facing away from viewer and shadow with doge and burn tools
Step 6: select smaller surfaces and shade with dodge and burn
Step 7: use paintbrush tool to ad highlights
Step 8: zoom out and make sure form is reading and lightsource is consistant
Step 9: add a new layer and zoom out, using a large soft brush, lay in a simple background that reinforces the ligh scheme.
Step 10: add a second tone to the background and erase it out from behind the secondary sketch
Step 11: Select the side panel using the polygon laso and copy and paste it onto a new layer. To create the look of a white panel increase the brightness on this layer
step 12: Select the front face plate and copy and paste onto a new layer
Sep 13: Using the hue saturation window add color to the front panel. Check the "colorize" box and use the sliders to reach the desired color.
Step 14: Copy yhe base shading layer and use brightness contrast to darken this part
Step 15: with the linework layer off you can see how slopy the rendering is
Step 16: using the add noise filter I add noise to the background and the face plate layers to add some texture to the sketch
The final: Again this is just one of many quick ways to show an idea to others.
