Introduction

In 2020 I got a request from Lumas, asking if I would be interested in creating images of mid-century modern architecture with a special focus on Palm Springs, California. They would sell them as limited high quality prints in their galleries all over the world. What a request! They didn't have to ask me twice.

The idea was to create images of non-existing houses reminiscent of that style. Of course, my designs are highly inspired by the works of Neutra, Koenig, Lautner, Wexler, Frey and so on. Focus was to design it so it could actually be built; with functional floor plans and perfect adaptation to the environment.

Mohave Valley, one of those projects was especially inspired by Marmol Radziner's prefab homes. I had already designed this house back in 2008, for the purpose of my diploma work at the multimedia academy. It served as a 3d interactive walk through experience, which was quite a new thing back then.

This is how it looked like in 2008:

Step 1: Modeling

The 3d model I did 12 years ago wasn't detailed enough. Also, I knew that I wanted to change the project to some extent. It would be the best to remodel the whole thing. It turned out to be pretty easy and straight forward. Here's an overview of the house model.



While modeling I usually add some placeholder materials with random colors, which makes it easier to work with. Most edges are not beveled through modeling. For low bevels and objects in the distance I usually just use the round edges option from the material. Window panes are hidden, but there are two panes in each window, modeled from simple cubes 2mm thick, with 7mm space in between.

Step 2: Lighting

Before adding materials I usually start testing some light scenarios. Although it was clear that it would be a late evening scene, I tested other options to make sure I didn't miss any potentially great shots.

To do this I usually use a neutral grey override material, but exclude the glass material from the windows, to keep the reflections. I mostly start with a Vray sun + sky (upper left) to find the best sun angle and direction. Then I tested some HDRIs (some PG Skies, Vizpark, HDRMAPS and HDRI Haven).

I ended up with 12 options which all could have worked fine. I left them for the moment and would decide while making the composition. (Side note: never ever send 12 lighting options to a client!)

Step 3: Materials

There is nothing too fancy about the materials. The most important component in the majority of materials is the texture. In order to get realistic results, using high res textures is a must. Here are three materials of that I think are the most interesting.

Soil: this one is pretty simple to setup. I used an 8k ground texture from textures.com which does most of the job. To get a more uneven look I mixed it with an noise shader. And finally using the according height map for displacement. The thousands of little stones and grasses distributed by MoGraph sell it even better.





Concrete: I used a VrayDirt material to get brighter edges where the concrete gets worn out. To get real broken edges I used a bevel deformer and displacement. Every block was rotated and moved ever so slightly, to get a more natural look. A massive 10k texture from extremetextures.com was used.





Facade: to get the patina look I've also used a VrayDirt material. Textures and noise shaders stacked on top of each other created a unique seamless steel material. Everything else was pretty basic.

Step 4: Composition

Composition along with lighting are the most important parts of an image; it's what makes or breaks it - almost more important than the subject itself (you can make good images from ugly houses too). That's why I recommend never to shortcut this step.

I didn't end up with tons of options because I was only looking for hero shots. The problem here is that it depends on the surroundings, which are, unfortunately not built yet. You have to imagine it.

Which format you choose is also to be considered. Landscape, portrait or square, each one has its own impact. Generally speaking, if you want to emphasize the height of a building then you should use a vertical format. On the other hand, a horizontal format emphasizes the overall site. In this project it's a one story building in a almost flat endless desert environment, which I really want to highlight. So, landscape format was the obvious choice here. The portrait format would focus too much on the pool and the sky. While, with a square format you simply wouldn't have any advantage.



I came up with three options; one 2-point perspective and two 1-point perspective. The 1-point perspectives are usually the most pleasing ones. The lines parallel to the frame bring order and calm the composition, which is usually what you're looking for in architectural photography.

The camera is placed lower than the average eye level, about 1 meter above the ground, which again emphasizes horizontal perception. But then shifted upwards to get a bit more sky. Focal lens is 22mm and 16mm. ISO 100, f/5.8, 1/380s for the blue skies. ISO 700, f/3, 1/50 for the pink skies.

I would then test the three camera options in a further selected set of lighting scenarios and then pick the ones that work best in each situation.



The color pallet, the object arrangement, and other additions will be part of the composition. Therefore, the final composition will then be nailed.

One of my favorite youtube channel, Steven Brooke Architectural Photography use to say “everything is compositional, if it doesn't help the composition it hurts the composition”. (highly recommended https://www.youtube.com/@stevenbrookephotography)

Step 5: Vegetation

After the model, light, materials and composition are ready, it is time to bring the scene to life with some vegetation. This is usually the most time consuming part. And a large proportion goes into finding the right 3d models. I used plants from HQ Plants, Vizpark and Evermotion. To pick the right ones I usually just place them in front of the camera and do test renders.



The terrain and the background hills consist of simple planes. 26 parametric square planes, sized from 400 to 1600 meters, elevated through noise shaders. And one highly subdivided plane for the foreground, sized 60x70 meters, modeled manually.



The distribution is mainly done with MoGraph. I placed the bigger objects and the objects closer to the camera manually. Below are the views of one of the background planes with and without distributed objects (about 30k objects per plane), and the foreground terrain with and without objects (2093 plants and countless little rocks and grasses).



If you'd like to have more in depth information about the distribution with MoGraph, the elevation with noise shaders and rocks with displacement then check my making of desert hills: guachinarte.com/insight/item/making-of-desert-hills

Also, I went through the complete distribution process with MoGraph on similar projects in the following making ofs: guachinarte.com/insight/items/mograph

Here are some crops of the vegetation.

Step 6: Post

There is nothing extraordinary about post-processing. But as with every previous step, you should not shortcut it. I usually spend a lot of time fine tuning the image in Photoshop, even though sometimes the difference between the raw render and the final image seems minimal, but they are crucial.

The final raw render is an 8k at 16bit, which is normally enough for bigger high res prints and basic post production. There is not much of an advantage if you go bigger.

The main steps I usually go through are 1st: correcting minor texture or other mistakes, if there are any. 2nd: render passes like reflection, specular and z-depth. 3rd: controlling major contrast and colors. 4th: filters (luts). 5th: camera raw filter, sharpening, lens correction and add noise to finalize the image.

That was it! I hope you could follow my process. Let me know. If you have any questions, feel free to ask in the comment section below.
