Elements of each car were lassoed and made as a separate layer in PhotoShop. This permitted me to alter separately the levels, brightness, contrast, hue, saturation, lightness and opacity of individual elements of the car. Chrome was always kept at 100% opacity. Glass was generally set at 33% to permit the background to be seen through it with a blue green tint of the suggested Polaroid glass. Opacity of painted sheet metal was lowered to a range of zero to 30%. Areas of the sheet metal were brought to the foreground. Creating rhe dozen or so layers and playing with the color and space of the total picture required from twelve to twenty hours per picture.
