Studio HDR is a collection of 53 custom HDR maps used to quickly light your models. While there are a lot of HDRIs out there, this collection focuses on controlled studio lighting. Most of the lighting is a neutral white, while others include touches of blue and orange. I have included a render scene with an old model I sculpted for both Blender 2.79b and Maya 2018.
