Lighting with HDR & matching backplate

#1

Hi all, I’ve been scouring the depths of the internet in search of an answer, but can’t seem to find one. Hopefully one of you rendering gurus will be able to shed some light on the matter :wink:

So as you know, using an HDR 360 image with matching backplate is a great way to render PR images of models, such as cars, with accurate lighting and nice backgrounds. But great HDRs with matching backplates are hard to come by on the internet, and if you find them they are super expensive. On the other hand, there are a ton of super HDRs available for free BUT without backplates.

So my question is, is there any way one can produce quality, accurate backplates from high res 360 HDR images? That way we could just use any HDR and make our backplates. And lighting + reflections would be way more accurate as both are produced from the same image.

Your input would be appreciated!

yes this can work, but the HDR has to be very high resolution because for example a 50mm lens only ‘sees’ an very small percentage of a 360 degree latlong image. 16k or higher for sure. Also, its better to use your spherical HDR as the backplate directly in post for best sharpness. if you render it out from 3d, itll be softer than normal.

If you are looking to capture hi rez 360 views, the best lens and camera combination I have used is a nikon D7100 or anyother crop sensor camera with a Sigma 8mm fisheye lens. This gives you a 40x20inches at 300DPI spherical images there is a post procesing workflow and customeised setting to prodcus one.
