4/8/2023 0 Comments Easyhdr forumUnfortunately, the easyHDR doesn’t support OpenEXR format, and I’m not really sure that it would be a cure. the “easyHDR” makes my pictures very greeny. I found that some applications are displaying identical HDR pictures with dramatic color cast. I tried to open Radiance HDR generated by Picturenaut in another HDR programs. double sized in comparison with the Radiance HDR one.ĭoes it mean that EXR is saved w/o any compression in Picturenaut? But when I generated HDR image in Picturenaut and saved it in both formats, the EXR file was approx. to HDRI Handbook, the OpenEXR files should be smaller than Radiance HDRs. I have some questions regarding OpenEXR and Radiance HDR.Īcc. So I thought this can be done with any image.I’m just reading the HDRI Handbook (Czech edition) and playing with Picturenaut and some other HDR tools. On the other side, I have heared and read several times, that nowadays almost every digital production(animation or real) is tonemapped during post processing to get a "filmed by a real camera" look and feel. But your explanation makes everything clearer. I always saw it as a kind of bonus feature. However, I have never noticed tonemapping as part of the render engine. I have worked with both render engines for quite a while, so I know the differences. When you use the tonemapping controls it is literally like using similar functions on a camera, because it can treat all of that light as a real-world thing. This is important to note because what Lux stores when it's rendering is not a static image, but rather the light information which is hitting the camera. Light in 3Delight is far more artificial in nature and can break the known real-world laws of physics such as passing through solid objects. ]The tonemapping settings in Luxrender work because it uses a physical-based rendering engine where light is calculated as it would be in the real world. On the upside, it's for that reason that 3DL can do special effects a bit easier than it would be to do using Luxrender. Luxrender is an unbiased engine, while 3DL is a biased engine. Both are extremely different in the way they handle materials and lighting, so there's no way you can mix and match the two. Unfortunately, comparing Luxrender to 3DL is like comparing apples to oranges. You can also create shader cameras which may help in this process. However, as mentioned above, you might be able to fake it using various different filters and effects. When you use the tonemapping controls it is literally like using similar functions on a camera, because it can treat all of that light as a real-world thing.īecause of this, there is no way to get a real tonemapping system onto 3Delight. Thanks in advance for your suggestions!The tonemapping settings in Luxrender work because it uses a physical-based rendering engine where light is calculated as it would be in the real world. Now, is this possible for 3Delight renders too? Is there a (cheap or free) standalone tonemapping software with the same controls? Or can I load rendered images into Luxrender for tonemapping?
