Making of Queen Alia Airport

Marcin ‘NEB’ Jastrzebski’s ‘Queen Alia Airport’ visual, recreating the real deal designed by Foster + Partners in Amman, Jordan, awarded him with Best Visualization of the Week NO. 15/2016 for a remarkable CG remake modeled with Modo and Cinema4d, rendered with Corona Renderer and masterfully orchestrated for the final result in Photoshop. Follow this Making of Queen Alia Airport article as Marcin describes his process, focusing more on key principals then the technical aspects. Enjoy!

Introduction

When I started writing this Making of Queen Alia Airport article, I was thinking what should I tell about it. Finally, I decided to write about my understanding of the image creation process, not being focused on technical details like modeling, rendering, and light setups. As a matter of fact, most questions I receive have to do with general “large concepts” of any creation process and which are independent of technical aspects.

This was my first real work made with Corona renderer.

When I started working on the Queen Alia project I had two ideas for the final mood and light :

  • A sunset and strong warm light with intense colors.
  • A cold rainy mood with heavy rain.

I always try to start a new project when I have a ready plan for what I want to accomplish with it. By that, I refer to the main concept of the image and the main assumptions about the final effect.

In the end, I decided to make the rainy weather view. I began gathering reference materials for the overall mood and some for the rainy day and effects related to this.

Because I decided to make a lot of work in 2d postproduction for this work I added to my reference images rain streets paintings of the great artist Mike Barr. I wanted the final image to be color consistent with clear ordered composition and also beside this dynamized due to the fact that the airport is a heavy traffic place.

3d Modeling

I relied on photos and images and image blueprints…

The modeling stage was quite difficult for me due to the fact that I didn’t find better blueprints of the Queen Alia project on the internet. I Mainly had problems with the roofing organic shapes… which is the main feature of this airport.

I modeled these elements in Modo using spline patch modeling technique.

After freezing these shapes I created splines for the groove lines which exist in the roofing. It was a base to create boolean objects and cut them in the mentioned roof parts and divide parts of the concrete shapes.

I made the rest of the scene models very quickly without too many details and imported them into Cinema 4D to set the draft scene and make a final decision about camera point of view.

After this important decision I came back to Modo and finished the modeling stage but only for the visible parts. I avoided modeling unnecessary things this way.

After importing the finished models again to C4D, I cloned them as instance objects and set the scene for the final view. I planned to make the entire background space in post-production.

Rendering with Corona Renderer

I made the final render in Corona renderer.

It was my first big project done with this renderer after previously done only small and simple interior test scenes. I’m really impressed how effectively Corona Renderer works on both platforms (I used it on both 3dsmax and C4D). The light setup, material editing, displacement and other features work great and everything is easy to learn and use.

Finally, those factors make the work with Corona Renderer very effective and we can achieve desired effects in render without problems. Corona Renderer material editor looks too simple for me, coming to it from Maxwell Render. But from another side, this is the strong point consistent with the main philosophy of the Corona Renderer creators. They assume to make Corona as a powerful and advanced renderer with easy and effective use which is visible even in the A5 version for Cinema 4D.

There are a lot of great opinions about Corona Renderer. We can see many great works done with it every day on the internet. Apart from the great quality and fast render, I decided to learn and use Corona Renderer in view of great and expanded multipass system and great antialiasing. Those factors are very desirable in post-production works.

Anti-aliasing quality is crucial if we use a lot of additional channels and masks during post-production stage to separate many image parts. Great quality of rendered additional channels makes our work smooth.

My Photoshop Layers Scheme :

I decided to make the final render at 6000 pixels width resolution despite the fact that I knew that I would present it at half of that resolution version.

High resolution connected with mentioned Corona Renderer quality ensures very comfortable work at the post-production stage. If I remember correctly no refine masks were needed during the work. That was cool!

The light setup and render settings were simple. I used a cloudy HDRI image taken from DutchSkies library and loaded it into a standard Corona shader in the diffuse and emission slots. Added it to the sky (the Corona sky tag was removed) and corrected a little by texture filter.

I made simple planes for interior artificial lights (positioned under the ceiling) and used Evermotion objects from lights library for exterior lights. I added to all of them simple emission shaders with warm color for interior lighting and aquamarine color tint for exterior lighting.

Camera settings were corrected to the environment strength and I changed the white balance value from default 6500 to 5500 to achieve a cold mood. I turned on the camera object motion blur for moving cars objects which I used in this project. I just animated two cars movement through ten frames, set camera shutter speed such as in the real world to 1/4 sec value and rendered the fifth frame when cars were nicely moving. The result was realistic and I decided to make this effect directly in the render and not in post production.

As I mentioned before, I made 6000×3600 pixels final render. I don’t remember the rendering time and how many passes I achieved. I just let it rendering during the night. If I haven’t a strict deadline I get every opportunity to reach the best render quality as possible.

The raw render was prepared for post-production and tone mapping. I saved it as 32-bit EXR file and made initial corrections with Arion FX. Usually, I use Arion for main corrections and also for bloom effect.

The Composition

From the beginning, I had a ready main concept for this image, but of course, a lot of elements can be determined during the whole creation process.

I decided to show the beautiful roofing shapes and monumental architecture but also, I wanted to show the open outside space to make a field for the rain effect. It needed to get the right balance in the final composition consistent with my ideas.

A camera is a basic tool which we use to show the architecture. For me, one of the initial questions is how to set the focal length. How deep I should distort the building shapes by using wide angle focal length or if I should avoid it and use more close to standard values or even a telelens.

In this case, I have set the camera focal length to 28mm for two reasons. Such as in real world 28mm for full frame digital cameras is quite nice wide angle setup. Firstly, I don’t need to distort too much the original organic roofing shapes because they are attractive in their own form. Secondly, to make a dynamic composition a wide angle helped a lot ( please look at the picture below) and additionally emphasize the roofing shapes in the top right part of the image. 28mm focal length was right to keep a good balance between those assumptions. In this way, I achieved nice roofing shapes and also could show enough outside space.

I divided the main composition to a few areas and tried to predict the colors and details for them. First is the main cold color mood which gives the biggest influence on the entire image.

queen-alia-00016

The second is a light gradient under the roofing. It ensures nice light effect but also, following the darkness in the depth of the image ensures good conditions to emphasize the interior light.

queen-alia-00017

The interior space covers a small area of the whole image but for me, it’s important too. After all, it’s an airport! I used warm light for this part as an opposite to the cold main part. The small warm light part of the view focuses our attention quite effectively and enough by this way.

queen-alia-00018

Without overloading the composition, I added additional elements like cars and people carefully. The most important point are the people located beside the red car. I avoided the central position (in most cases it’s a composition mistake) and located them close to one of the important composition points which are consistent with basic photography rules.

queen-alia-00019

The first plan composition I connected mainly by three cars. It’s enough for the view. I was careful not to over burn the car lights. Bright light will focus our attention too much.

queen-alia-00020

In my opinion, dividing the entire composition to a few areas helps us keep the clear and distinct final effect. I mean that we can focus on main aspects of the view and move step by step to a more detailed effect on the way to the final image without loosing the main concept among a lot of creative decisions.

The Colors

Besides the composition, the colors are also extremely important. The starting point was to set the camera’s white balance value to 5500k. It gave me a basic cold mood. The cloudy almost gray HDRI environment image helped too. These factors aside, I decided to add artificial lights located under the roofing and warm interior light. In this case, I imagined how the colors of the image could look like and added the lights which would be consistent with that.

The following images explain the main color concept.

Artificial lights. Warm bright interior and little aquamarine for roofing reflectors.

I modified some simply rendered car lights with reference photographs and made them not too bright as I mentioned before.

The entire colors palette scheme for this image. There are four main groups.

queen-alia-00024

During the work in the post-production stage, I made all additional elements (like people) consistent with the mentioned colors palette. The image below shows typical additional element correction.

I corrected the colors with the help of masks. I also changed the shades of rendered cars and many parts of the building, pavement, walls, and street.

I added these people (assets from VIShopper in this case) in the left corner, acting as the ones looking at the sky… It’s an airport but putting an airplane in the sky would be too much for this composition. A subtle hint could do the trick too… who didn’t look up to the sky arriving at an airport, ha?

The Post Production

To control the wet effects for crucial surfaces, I made two versions of them and rendered separately. I just rendered a dry version of the ground surfaces and a high reflective wet version with additional reflection pass. It gives me a full control creating the right effects related to image parts which are under the roofing or outside.

For example, I created a mask between the road’s dry and wet versions and paint cars trails. The visible part of the road is under the roofing but I created an idea that the cars may carry a rain water from outside on their tires. This effect disappears into the deep of the image. I added also the road mark lines in photoshop.

The interior hall details were added in photoshop from mixed different photographs of the similar interior spaces. Finally, I added a bloom effect to this part.

queen-alia-00028

The aquamarine color of the roofing reflectors light was important to the entire image look. Besides the car lights in the lower level (white on the left and red on the right) these lights were also a great reason to show a camera wet lens obstacles. This effect also emphasizes the overall rainy mood.

queen-alia-00029

I added the entire background space in photoshop. This is a quick and effective way to achieve this and avoid building a large scale scene space with 3d objects. Due to rainy weather, it was quite easy because there is a strong fog effect which I made by using the Z-Depth channels.

By the way, I rendered two different Z-Depth passes with Corona Renderer. One covered the space from camera to far distant and the second limited little more for the middle distant to far background space. It allows editing more flexible a fog effect for large-scale scenes renders.

queen-alia-00030

I made the rain using photoshop brushes. Paint it on different layers and set gradients for various levels of visibility. Special brushes were used for this to get the right look.

queen-alia-00031

Cars in the first level are very visible in details and it was necessary to make them affected by the rain. I replace rendered reflectors by photographs and added wet and dirty details on the cars.

queen-alia-00032

Finally, I made a little color correction to the final image in Lightroom and after that in Red Giant Looks plugin for After Effects. It was mainly the bloom effect, vignette especially for the bottom part of the image and right side of the roofing and chromatic aberration.

That’s all!

I really enjoyed working on this image and I hope that you enjoyed reading the Making of Queen Alia Airport.

Thank you, Ronen, for the invitation and opportunity to present part of my work on your great blog again!

    Thanks emyjm! I don’t know if modo is the best tool for organic modeling but I just know this software 🙂 I used modo from 103 version and it’s natural to use it for me.

    great image, and description of workflow.  Could you tell a little about how long the entire process took, and how much of the overall time was spent just in pshop?

    Thank you! I don’t remember the entire modeling process time. I started this project in February. I spent a few  days to model everything and set initial scene and make decission about final camera view. After that I stopped this project because I had a lot of commercial work to do. I re-started it in the middle of April after refreshing Corona to A5 version. I spent two or three days to finnish the models and scene with Corona materials, light setting etc. and render the final images. The photoshop work took three days.It is a personal project and I made it among the other works but for the postproduction stageI in PS I spent full three days working only on that 🙂
