Rendering in Photoshop
Page 2 of 3


 

Start by scanning in a sketch that you want to use. The scanner should generally be set to give an image size in pixels of 1024x768 to 1600x1200 (or larger) depending on your working screen size, and planned print size.

It doesn't matter if the car was sketched on excellent marker paper or on a napkin at 'In-n-Out Burger'. It only needs to be just the thing you like and you want to present. Import the scan into Photoshop, duplicate the layer, clear the background layer, and set the transparency of the copied layer to 35%. This way you can see the sketch, still have a white background, and make the underlay sketch invisible once you're finished.

Block in the basic colors with 200-300 size airbrushes. In this case the car was going to be red, and I like using the warm and cold sides of the real world in my sketches to enhance the sculpture. Apply broad strokes of airbrush, and then simply erase the areas that form the hard reflections manually. This gives a more spontaneous effect and is quick.

On a new layer again quickly airbrush the soft sky reflections, also here using the warm and cold colors. And again manually erase the overflow of airbrush. Set the eraser to Airbrush and use a 65-100 opacity. Working on a separate layer enables you to erase these areas with a large soft eraser brush, while leaving the hard reflection areas undisturbed, and all without any masking.

Similarly build up the warm and cool glass reflections on their own layers, using a large airbrush, followed by a hard-edged eraser brush to redefine the edges. Initially use the colors lightly, then duplicate that layer and erase the highlight parts of the interior off of the first glass layer. This way it seems you can look through the car, which enhances the realism.

This is the time to put the car on the ground. Make a quick path in the path tools menu, and adjust it to fit the area of shadow marked off in the sketch. In the path menu save this path, go to 'Make Selection' with a zero Feather, and go to the layer menu to make a new layer. On this layer you fill the selection with the background color you want, and here I have added a few brush strokes in different colors to add warmth.
