HDRI and how it can bring my product to life in a video (Part 2)

Final Render using HDRi

Since it’s introduction, High Dynamic Range imaging has revolutionised digital post-processing in imaging, film and photography, raising the standard of creative freedom to an unprecedented level by capturing everything from the brightest of highlights to the darkest of shadows. High-Dynamic-Range-imaging achieves these results by producing a broader tonal-range than previously possible using only standard digital-imaging techniques.

HDRi has signalled the dawn of lossless image editing by giving full control over exposure levels and allowing for any scene’s contrast to be mastered without the need for artificial lighting – all the while maintaining lighting information from a scene so that it may be altered or revised where necessary, time and time again.

As explained in our previous blog post, when utilised with panoramic photography, this light information can even be used to render 3D-built objects with surprisingly realistic results. Without HDR/HDRi, the VFX-laden Hollywood blockbusters we have come to know and love would not be possible. Indeed, the movie industry as it stands would almost cease to exist!
In the example shown here, firstly, all reference and relevant information concerning the product or service is compiled and then modelled.

Once the product is modelled accurately to the correct dimensions, the HDRi information is applied to the scene or sequence and the model is assigned materials which react with the lighting information from the HDR.

The panoramic shots are compiled to give the environment dimension, this information is then mapped onto the product, helping to produce real-world reflections, highlights and shadows on and around the modelled product.

As the technology has advanced and become readily available, so too are the results more attainable for even small businesses. HDR imaging has become commonplace now, not only in the big-budget blockbusters, but also in smaller film and television productions, advertising commercials, right down to catalogued images of products.

At GLUE, we continually strive to refine these techniques to perfection, effortlessly blurring the line between reality and imagination.
