CORONA RENDERER AND TONE MAPPING; SUPERELITE PHOTOREALISM SIMPLIFIED FOR YOU!
So many different renderers are available across the web. Choosing a special renderer that meets all the requirements for your project will make a huge difference. In all our projects, our main objective is to merge the daylight and the lamp light. We have worked for some of the top companies in the world including D’ Antonia, and “home to win” (The Canadian TV show). Here are some of our latest, awe inspiring projects:
This is quite impressive, right? We already know your next burning question; how do we accomplish 100% photorealistic results? A premium, 3D rendering scheme that builds incomparable realism out of the ordinary. Corona renderer is a modern, fast, and efficient tool and we are here to share our special knowledge with you on how to use it to produce excellent results. It is a simple and stable complete package that focuses mainly on changing the light intensities during and after rendering. You do not have to be an expert. In just a few steps, you can also create similar visuals straight from your camera using Corona Renderer and Tone Mapping!
- We chose the following scene for the tutelage. It offers the perfect combination of both artificial lighting from the lamps and natural lighting from the window.
- We are going to use the cursor to highlight the important features.
The corona light simulates the halogen lights visible around the ceiling and on top of the orchid.
- We used corona lights with the intensity of 900 lumens:
- We did not choose the default units because they would show how much power the light bulb takes. Lumens on the other hand are a better option because it is possible to know how much the light bulb gives by looking against a light bulb chart:
From the chart, a LED bulb needing only 8w will give 450 lumens. For a halogen light producing 800 lumens, it takes 43 watts.
- For the color, we used Kelvin units to set the temperature. For this interior, we decided to use a little warm light (4500K):
- This is because it is possible to check the temperature of each light bulb against the chart below:
- The disk shape gives you the direction of the light:
- We also turned off visibility and turned on the IES (far right corner)
- This is because IES would give us this beautiful light shape here:
- To set up this light scheme, you will be required to turn off the environment before setting the lamp light to avoid making the scene too bright and therefore seeming unrealistic:
- To get just the right amount of light, we set 12 halogen lights on the ceiling and then looked at what they would appear like in the interactive arrangement:
- These were the results:
As you can see, some of the parts are too bright. We need to adjust them with Tone Mapping
- The exposure makes the whole scene lighter or darker. We decided to set it at 1. The highlight compress enables us to get rid of the too much bright parts. We decided to set it at 2.5. Take care not to use too much highlight compress because your picture will lose the contrast. The white balance also enables us to set the temperature of the picture. We set it at 5500K. We will not use the contrast because the scene is contrasting enough already.
- After making sure that the lighting is okay, we can modify the environment by setting the overall multiplier under the processing tab to one and copying it into environment instant smart.
- After running interactive once more, these were the results:
As you can see, the HD alignment is too dark around the window (where the cursor is). We decided to change the overall multiplier to 20:
These were the results:
- We get a perfect cloudy day and relatively warm interior impression!
- For a finer touch, we adjusted the exposure to 1.5 and highlight compress to 3 units. This was the final result:
