3D Collective – Real Light 24 HDRI Pro Pack 2 8K

24 HDRI Pro Pack 2 

3D Collective – Real Light 24 HDRI Pro Pack 2 8K : One of the most popular methods, when lighting a 3D project, is what we know as IBL (Image Base Lighting), which consists of using a panoramic 360º high dynamic range image (HDRi) as a lighting source, to to reproduce as accurate as possible, the actual sky conditions at the time of capture. However, this technique has some important limitations and inconvenients, and that is why incorrect HDRi can cause problems when it comes to lighting our projects, sometimes causing worse results than automatic sky systems and sun that are included in most render engines.

This second HDRi Pro Pack, contains a selection of 24 HDRi designed to work independently of the Pack01, but at the same time complements it perfectly, providing new lighting alternatives for professionals.

Also in this new Pro Pack, you will find high resolution images taken at the time each HDRi was captured. These images are ideal to be used as backplates in your renders since they fully coincide with the characteristics of the HDRi itself.

WHAT DOES THIS PACK INCLUDES?

This HDRi Pro Pack 02 contains a collection of 24 high-resolution (16K) calibrated HDRi. The skies have been photographed in different seasons of the year, with very varied weather conditions and with a wide variety of time frames, so that you can find the perfect lighting for your project.

In addition, in this new Pack, all HDRi are complemented by up to 8 high-resolution (8K) photographs in CR2 format, obtained at the time and place where the HDRi was obtained, in order to be incorporated as Backplates in your renders.

DYNAMIC RANGE

When capturing HDRi in skies with visible sun, one of the most common problems is the lack of dynamic range, due to the limitations of any real camera. 3D Collective’s HDRi have all the necessary dynamic range so you don’t have to modify anything in the file, and so that you can obtain real exposure value and luminosity in your projects. Simply load one of our HDRi to have a realistic lighting and a camera exposure matching real values.

REAL EXPOSURE VALUE IN 3D

Another important challenge when creating this HDRi Skies Pack, has been to calibrate the HDRi exposure so that they are a true copy of reality. This allows us to create an exact copy of the real world in our 3D applications, obtaining a correct exposure of our camera in the project, and facilitating the incorporation of artificial lights with real luminosity values.

In our first HDRi Pack we offered a multiplication value that allowed us to guarantee correct exposure to the user. In this new pack we have managed to improve the procedure and ALL skies use a multiplier of 1, so that it is no longer necessary to modify the multiplier in each sky. Simply drag your sky to any 3D program to obtain absolute exposure values.

HIGH QUALITY HDRI AND 16K RESOLUTION

When it comes to capturing HDRi images, the most common method, is the use of fisheye lenses that allow a very fast capture of the photographs due to their wide angle of vision. However, this type of lens usually has problems of chromatic aberrations and they don’t allow to generate images of high resolution. In order to offer high quality 16K HDRi, all the skies of this pack have been captured with high resolution (50+ MP) cameras and high-angle rectilinear super angular lenses to minimize chromatic aberrations, allowing an original file of more than 24K which is then reduced to the final 16K HDRi file to reduce noise and guarantee the highest quality standards.

When using HDRi, there are several possibilities; There’s the HDRi that besides the sky contains the original horizon of the place of capture, this can cause that the trees, buildings, mountains, etc. from the location of the capture, are reflected in our projects. This might be useful to make a quick LookDev, however, when presenting a final project, it’s preferable to have independent control over the sky and the horizon.

In this new Pro Pack, all our HDRi have been captured and modified to eliminate any intrusive element on the horizon, keeping only elements such as distant small sized mountains that allow us to achieve a more realistic horizon and add important details when we use the HDRi as a background.

We have also extended the HDRi below the horizon line to avoid problems in projects at sea or near level 0.

Enjoy!
