It is bold, creates stark contrast and the deep colour of the sky tints shadows with pleasant blueish hues.ġ) Dynamic Range is a complicated subject that we breezed through. PG1714 is my first go-to HDRI when I aim at the punchy commercial daylight scenario. I have contrarily chosen something much more mundane here (it's not that I don't like a good sugary sunset) and I hope it will be a more useful suggestion. But what will make you grow as an artist is to break the routine, try something new and plainly have some fun along the wayīartosz: It is easy to appreciate an HDRI with a dramatic sky of golden or blue hour. For the past five years or so, I have used mostly PG 1658, which I wholeheartedly recommend to this very day. Test your “Gamma” and “Exposure” values every time, or even jump into Photoshop and take it from there.Īrtur: I’d love to encourage you and test whatever HDRI gets into your hands. Every single HDRI will have different values to make it work. Instead of pinpointing the specific location, you should just use your creative freedom to alter and adjust your HDRI, respectively. Even the color of the sky and visible cloud formations will differ accordingly.

Now, what to keep in mind when you're looking for a perfect HDRI:Īt noon, the sun’s latitude will be totally different in December in Norway than in June in Spain. Meanwhile, there will be a lot more rays shooting from the sky simply because its surface is greater. Sun will shoot considerably brighter rays than the sky. All of those rays have different intensities and colors. Every pixel in HDRI shoots a ray of light into the scene 3. When we speak about illumination, we mean all of the light traveling through the scene (global illumination). HDRIs used for illumination are mostly spherical maps, which we can set as our environment.

You can use it inside 3d software as an illumination system. HDRI lets you set the lighting conditions of a given time and space. What does it mean to a CG artist, though? The parts of an image that appear pure white (or black) consist of many useful light features. This way, you can record many real-world scenes containing very bright, direct sunlight as well as extreme shade. That means that HDRI has a greater range of brightness (more than 0 - 255) 2. It is the opposite of a JPEG, an LDRI (Low Dynamic Range Image). HDRI is, in fact, a High Dynamic Range Image 1.
