Paint a Realistic Intercooler Photoshop Tutorial
Open a new file in Photoshop, with Transparent background. The size I choose is 600x300 pixels. Then rename the Layer 1, in Background. Fill it with black colour. Make a new layer and name it, Contour or Shape, or, what you want, to know that is the contour. Take the Pentool (P), and draw the intercooler contour.( I've choose this shape, because it's a very popular intercooler shape, that many choppers use, and because this shape is " full". You can see 90% of intercooler's interface. ) When you finished the shape, with Brush Tool (B) set at 2px and a green colour, with Pen Tool, right click on the file and choose Stroke Path. After that, press once the Delete button, on your keyboard, to delete the path. If you want to skip this step, you can download the PSD file below.
Decrease the Contour layer's opacity, to 5-10%. Make a new Group under Contour layer, and name it Exterior Parts. Then make selections to side parts, with 0.3 feather. Create a new layer, and fill the selections with # 353535 colour. Then make a new selection to top part, with 0.3 feather, create a new layer and fill it with #0F0F0F colour.
Now click once on side parts layer, in Exterior Parts group, and make 2 selections like these with 0.8 feather. Then take the Burn Tool (O), and use it. I've choose these selections to show the darken parts of intercooler.
Make a selection like this with feather 0.8, take the Dodge Tool and use it, like I did.
Make a new layer. After that, take Pen Tool, and following the shape, make a path to one of the side parts, like I did, and then, having the Brush Tool (B) at 2px size, stroke it, with #9B9B9B color. Take the Erase Tool (E) with a size of about 20px, and erase a bit the path at the start and at the end. Then do the same process to the other side, but using the same layer.
Create again a new layer, and repeat the process, but with pure white colour #FFFFFF. This time, erase much more the paths.
Make a new layer, choose Brush Tool (B) and with a brush of 9px and white colour #FFFFFF, make a point like that, on the top of part. Then, using Smudge Tool (R), smudge it like I did. After that, do exactly the same process, but this time, with a 5px brush and lower on the part, next to the pipe.
Make a new layer, and using Brush Tool and black colour #000000, make 2 points, in front side of the exterior parts, and smudge them, with Smudge Tool. Then set the layer's opacity to 56%.
Create a new Group, and a new layer. Make a selection, to the main part of intercooler, and fill it with #0B0B0B colour. Then go to Filter > Noise > Add noise.
Create a new layer, and having the Brush Tool at 3px size, take Pen Tool, and following the initial shape, make a line path. Then stroke it with #808080 colour. Duplicate the layer how many times is need, to fill the intercooler, with these lines. But, always follow the initial shape.
