Making Of 'Underground Escalator'
Research & Concept
Before starting this scene, I didn't make any drawings to help me out during the concept stage, but I did imagine the scene in my head and I knew how I was going to proceed with it.
I did some research about the system of the escalator in order to create my own design and to be able to reproduce it in the most realistic way possible. My goal was to create a dynamic vision of architecture with a fantastic atmosphere - not a simple representation.
Just one thing: at the beginning I decided to create this image for my final work studies, but in the end I didn't present it. There is two months work her after I decided to improve the scene for my portfolio. I worked for about during 1 week on the camera and atmosphere alone.
Modelling
For the modelling, I used 3ds Max 9 for the entire scene. The most important piece of this work was the escalator. So, I'll try now to detail the most important stages of the creation of this image, as best I can.
Firstly, I started to draw a spline to give the escalator a good shape. I kept the shape that I made because I could use it to correctly place all the steps of the escalator, and also to make the animation of the steps.
I transformed the spline in edit poly and began making the first extrude. I then connected all of the edges to in order to place the ramp of the escalator (for this object, I applied a "meshsmooth" in the smoothing group).
To create the ramp, I extruded the polygons in local normal.
Next, I connected all of the edges to subdivide the ramp, and I extruded ("by polygon") the polygons on the interior side of the ramp, to obtain the metal plates.
I rotated the polygons a little to achieve a small incline on the interior side.I also created a support below the escalator where I made a groove to place the ramp.
I some also added some screenshots of the others objects of the scene: steps, concrete slab...
The Position & Animation of the Steps
So, for the animation, I took the spline again that I used at the very beginning. I placed a first step at the bottom of the escalator and then applied a "path constraint" on the step.
I duplicated the step and changed the value of the "Along Path". Between two steps, I set a distance of 2,4. So, the first is at 47,3 and the following step is at 49,7. I repeated this action for each step of the escalator.

[Texturing]
On the two sides there is a concrete texture for the wall, and the other texture is the wood for the floor and the ceiling.

I have given here the others parameters for the metal of the escalator, the material for the steps, the rubber for the ramp and the material for the arrival part. I increased the subdivision of the metal of the escalator to reduce the noise of the material. You can see that I've also improved this parameter in the rendering parameters.

Lighting
For the render I used the V-Ray rendering engine. In order to obtain the atmosphere that I wanted, I made about a dozen tests with different views and lighting setups to get the image that I had imagined.
I placed just two "vraylights" in this scene. There is one white light at the top of the escalator; I put the multiplier of this light at 12 in order to have a big light (I improved the lighting in post-production but I'll explain this later in the Making Of!).

The other light was placed behind the camera so that I could have a source of lighting at the bottom, and to also see some detailed parts of the escalator. The multiplier of this light was set to 2 and I gave it a blue light.
I made the lights at the bottom just with a "Vraylight" material (multiplier at 4).
The environment of the scene is a grey colour (Grey: 100).
Rendering parameters
Here are the settings of my final rendering for this project (the values that you can see in these images are the values that I used for the high-resolution version, at 4000*2000 pixels):
Post-production
The post-production was done in Photoshop. I'll explain all of the effects that I applied on the image because there is a big difference between the image without the post-production and the final image.
Before adjusting the brightness, contrast and colour, I did some corrections on the reflection.
After the rendering I had some noise on the metal on the interior side of the escalator, and I used the tool stamp to remake a good reflection. You can see the correction made in the following images.

So, for the first step in my post-production work, I applied a "levels" layer to adjust the brightness and contrast (I'll improve it later with others layers, too).
Next, I duplicated the layer with the levels and applied a blur at 10-15 to the image. I made this effect so I could obtain a slight glow on the entire image, and to darken some parts of the image as well. I set this layer to either "overlay" or "soft light", and I played with the opacity of it, too.
After this step, I made a copy of this last effect and flattened all of the layers of the copy. So, on this last layer, I applied a filter - Distort > Diffuse Glow - with a white colour.
To change the colour of the image I used the "color balance" tool, moving the curser towards the red and yellow colours. I did this same action for the shadows, mid-tones and highlights.
And for the final effect, I took the following image and used it as an occlusion pass (before, I simply modified the brightness and contrast with a levels layer!).
And here is the final result.
