Note the two bands of sun color in the middle. But as you can see in the bottom row, already after lowering exposure by two stops, the sun in the hdri starts to go from bright white to light grey. The following maps look different, but the effect on your rendering will only be small.Ī good hdri map will keep the light sources bright when lowering exposure, while all other pixels will go darker and darker. Same goes for city environments and even interiors. The clouds seen from hill X look the same as the clouds seen from hill Y, so there's no use in 15 maps from the same area on the same day. Many collections contain dozens of maps from wide open exterior spaces. Make sure that when you buy a complete collection, that there is some variation in the environments.

But first read about some other aspects of what makes a good HDRI stand out. This is in fact what this article is about, so we'll get back to this topic later on. The most important thing is the actual dynamic range of the image.

This article will help you in doing just that, with a strong focus on the dynamic range which is usually overlooked, especially by the providers of HDRI maps.

Since you usually have to decide on buying HDRI maps from examining low dynamic range previews, it's important to know what to look for and how to spot bad quality maps. Many people don't seem to realize that there is more to a HDRI map than only a pretty picture.
