For the
finishing touches copy merge the whole image and paste the layer at the top (or
flatten the whole image)
To give it more impact you can then turn up the contrast to around +6. Feel free
to experiment with different amounts – but too much will look harsh.
Also you can create a colour layer which basically allows you to tint the
colours of the image below, without losing detail/ contrast. I used a blue
airbrush just over the top surfaces of the car to add a bit more interest.
Now the render is finished, although you can play with hue/ saturation levels if
you want different colour scheme.
If you
duplicate your original clean line art layer from stage 1 and bring that layer
all the way to the top. You can then invert the layer or bring its brightness up
to the max to get white lines.
You don’t have to do this, but white lines have more drama on a Canson style
render. You can then erase some back in darker areas etc.
The reason for doing this is to both enhance the sketch feel and define surface
breaks with a highlight rather than a black line.
I have also added centre highlights and a front glowing light
For the ground
reflection – quickly select and copy the side of the car including the wheels.
Then flip the layer vertically. Now distort that image until it roughly looks
about right. You may need to cut & move bits around, especially the wheel
reflections.
If you lower the layer opacity to around 10% then erase a few areas with an
airbrush to keep it purely as a suggestion – rather than anything accurately
rendered.
I have also added some white highlight steaks using a fine airbrush and paths
(see stage 1)
Add other details like rear light and headrest suggestion and some subtle
reflections.
Now the main
blocking in is finished we can create another MULTIPLY layer for extra shading,
mainly on the car body side.
Firstly select the whole body side from the nose to where the rear wishbone is.
You can now using a large light grey airbrush intensify and darken the whole
area to pull it out from the back ground. You can then select the rising sill
and darken that further to create a surface break. Fill in the areas inside the
wheels etc.
Its important to maintain a focal point – so I have made the car darker towards
to front left hand corner and lighter (faded) towards the rear and parts of the
car that are furthest away.
Remember your light layer should still be above this layer.
Create a
multiply layer for adding shade.
I created this layer beneath the light layer, so that light zones always stay
above. To be honest you can do this stage before the previous – I just like to
put light down first – it’s your preference.
I used a large dark grey, angled airbrush (don’t use black as you cant then add
more shade). If you change your brush tip shape you can make it more like a
marker pen stroke i.e. a thin block. This gives a more dynamic feel to the
darker elements.
Here I blocked in the main darker areas of the car including the ground shadow
to help lift the image out from the page.
The nice thing
about this technique is that you get to add light rather than leave areas
uncoloured to create lighter surfaces.
Create a new layer (normal). My light source, if you can imagine is above the
artists head shining down over the car. Defining a clear light source is
essential for describing surface changes. It’s worth while really analysing
where you want light to go.
For this I used a large soft airbrush with a low opacity of around 25. The
importance of using a large brush is to get a smooth gentle gradient; smaller
brushes can tend to create a muddy appearance if you’re not careful. Carefully
select various areas that would catch light using the path tool, which gives
very smooth crisp perimeters. You can build up white intensity towards the
middle of the image to add visual focus.
To get the
Canson paper effect create a MULTIPLY layer in Photoshop. This type of layer
allows you to still see through to your art work without reducing opacity
levels. Now you can use the gradient fill tool to fill the area with your
desired colour. I chose a deep purple to a medium grey. I find a graduated
colour change adds something more than just a flat one.
If you click and hold this tool it automatically generates a line that the
gradient will follow – so the longer the line the softer the gradient. I simply
went from the top of the image right down to the bottom. Then I selected the
side frame and reduced its saturation level until it went grey, though you could
achieve this simply by airbrushing over. You may also add around 1% noise to the
whole layer to give it texture.
I am a great
believer in producing a quick biro thumb nail before going into a more detailed
drawing. A quick biro sketch helps you ‘stay free’ before getting seriously into
a render.
Once you have done this, simply scan the image and drop a white layer with
reduced opacity over the top so you can still see your rough biro work.
On a new layer above the white sheet you can create the refined line art, using
the path tool and a fine brush. If you stoke the path with simulate pressure on,
you will get a nice taper to the line work. Once finished you can switch off the
rough sketch back ground or increase the white layer opacity to 100%. It’s also
essential to make sure your wheels/ tyres are in correct perspective as it
vastly improves any drawing.
