Want to improve photo realistic rendering? Here are some tips to help you create more lifelike renderings.

Did you know that the US construction industry contributes $10 trillion to the American economy each year? This is a huge amount of money and demonstrates the construction boom that exists in the US right now. 

However, even before a building has been constructed, it has to be marketed and in most cases sold or leased. To be able to do this effectively, you need to have a realistic rendering that will be both accurate and appeal to customers.

How can you create photo-realistic renderings that will convert to sales? Check out our guide to the 7 tips to create more lifelike renderings.

1. Use Bevelling Techniques

The goal of architectural rendering is to convey not only the scale but also the beauty of the finished construction. Elements that give away that this is a render and not a photograph are distracting to the viewer and give an air of un-professionalism. 

One of the basic ways to avoid this is the use of bevelling when rendering. Leaving sharp edges can be a dead giveaway. It shows that an image is an image and not a reality. Even man-made objects have at least a slight rounded edge.

Be sure to bevel most or all images. The effect of light hitting a rounded edge can even add to the 3-d effect in an image.

Learning to use, and not overuse, a bevelling tool. This should be one of the first skills that a renderer should master. 

2. IES Light Profiles

Correct lighting in a physical structure, especially a dwelling, adds beauty. It further gives an impression of space. This is why space and light planning is one of the main priorities of house buyers. 

Using IES Light Profiles to accomplish realistic lighting in renders is an effective way to illustrate space and light in a building. IES Light Profiles contain accurate photometric information. This means that they can be used to create realistic light-shape and luminance in a render.

This is an effective short-cut. Instead of calculating light behavior for each building or room that you create, these profiles can provide examples as a basis for accurate models.

3. Employ Depth of Field

Depth of field is famously employed by photographers and filmmakers to highlight picture elements that match the photographer's goal. It either brings an element to prominence or reduces the focus of the background to accomplish the same end. 

This can be employed either at render time or afterward in post-processing. Application of depth of field before render will give you greater control over the outcome. However, producing the same effect in the post-processing stages is faster. 

4. Add Chromatic Aberration

You may have seen the effects of Chromatic Aberration in photography. This occurs when colors slightly separate due to the camera lens not rendering them at the same convergence point. 

This, of course, does not happen naturally in CG renders. How can you fake it to give a more realistic rendering? Photoshop users can offset the red and blue channels by a pixel or two.

While this will provide realism to an image, remember that even in real photography an excess of Chromatic Aberration is considered unprofessional. Keep it to a minimum in your renders to avoid falling into the same trap. Subtlety is class in this context.

5. Specular Maps

Specular maps will not be a new concept to most experienced renderers. In short specular maps provide instructions to your render engine to provide a realistic level of gloss for each item.

For example, the sun shining through a window on a polished table will provide a non-uniform level of gloss or shine across the table. The specular map will indicate where the shine should focus and how much. 

Even on an object that does display relatively uniform glossiness, specular maps can be employed to help you indicate imperfections. Do we really want to show imperfections...?

6. Avoid Perfectionism

There is such a thing as too much perfection. If you are looking to create images that are photorealistic, you will need to incorporate flaws that may exist in the room or building. 

If you are looking to render an image of an existing room, flaws may already be evident. Be careful not to cover too many of these over. In other cases, the building may be new however the surroundings not.

Including negative elements that are not detrimental to the purpose of the drawing - especially for sales purposes - can give photorealism. 

If flaws are a step too far, give the room a lived-in feel. Add furniture items or other household belongings but not perfect tidiness. 

7. Add Asymmetry

Many people associate beauty with symmetry. This may be very achievable in the controlled environment of a rendering studio. Mathematically controlled models will be perfectly symmetrical.

However, much like in real-life - perfect symmetry is unrealistic and can be spotted by the human eye. Avoid sacrificing realism for perfect mathematics. Feel free to switch off symmetry and allow small variations for realism's sake. 

Realistic Rendering and Much More

Good quality image rendering can make the difference between a sale and no-sale, success and failure. The standard of image creation is so high that anything less than the best will immediately stand out.
