Once the scene was created, I made some render tests when applying the textures (I didn't texture the complete scene), and then started to render. I always prefer to make renders whenever I texture, because in this way I can correct any errors in the textures and materials. In the render tree I created the materials and applied the textures - some of which were created in Photoshop or taken from libraries of textures, giving greater photorealism to the image.
When rendering I used several passes in order to have more freedom, and I easily merged them in Photoshop, placing the reflection, alpha, AO, and so on, passes as I wanted (Fig.12 & Fig.13). The several passes made were: ambient/diffuse, shades, AO (ambient occlusion), reflection, specular, refraction, DOF (Fig.14), volumic (Fig.15) and alpha channels - one of the car and the other of the background. In this way, the final image could be mounted for much better effect.
Using Adobe Photoshop, I merged all the layers. I made some adjustments of the colour, saturation and brightness, and I applied an effect created by a Photoshop plug-in called "Bleach Bypass" (Fig.16). Very interesting!
Rendering is my favourite part because I can change the values or settings until I achieve the effect I personally want and like. I enjoy making many tests and creating various atmospheres, and then choosing the one I like the most. In this image, I finally added the depth of field (DOF) layer to create a slight defocusing effect on the back section, therefore simulating a camera focusing on the front and central part of the car. I added a slight noise layer and then applied the volumic layer to create a warmer atmosphere - more magic - and to give the car a touch of magnificence!
I was satisfied with the final image (Fig.17); although it's not a very complex model and is set on a simple plane, I wanted to create the scene as if it was a new concept for the classic car, something in the present day with all the improvements and comforts, whilst being faithful to the original. I didn't want to just make a copy of the car; I wanted to give it a personal touch.
