Hey all,
This is slightly off topic so please move if this is in the wrong place. I am looking to do a physical build of the cornell scene and do a 3D representation of it. The overall size will be between 12-20 inches square. The primary goal is to use it to as a controllable environment where I can research various aspects of rendering such as physical cameras and their effect on seeing color, complex light interactions, various materials etc... I already have a high end light booth, but I am wanting something custom that I can control various aspects of such as where the light will be coming from. Everything will be 3D printed or cnc'd so I can create various configurations. The biggest importance to me is color accuracy of the scene regarding materials and lights.
I have trying to find a d65 daylight light source, and it is proving more challenging than I anticipated. I want something that matches the daylight SPD as close as possible. A filtered tungsten would be ideal, but I can't find one. I've looked at high end LED's from waveformlighting that have a CRI and TCLI above 96, but they all have a spike in the blue wavelength and I'm unsure the impact that will have on color fidelity. I've also heard CRI is not a good indicator of quality, that TCLI or SSI is a better measurement. I've seen decent light quality measurement from the Apature Amaram series used for film shoots. I would prefer against a tube light, but I can make that work. I could buy a replacement fluoro tube from gti light if that's the right way to go. I am looking to spend less than $200 on the light, ideally.
The reason I want this type of light is two fold: 1. match the color standard for viewing and measuring colors in a lightbooth 2. match a light type that, from my understanding, is commonly used in render engines (sun and sky)
Have any of you dealt with this? Is there a light source you would recommend to go with?
I have attached a visualization of 3 of the most common SPD's for reference. I am looking to match the middle with a physical light.
Maybe a tl;dr: Does anyone have a link to a high quality light product that I could buy that would mimic filtered daylight? The ideal, as I understand it would follow the daylight d65 SPD.
