If enabled, the camera response curve doesn't tint the render result anymore. There is always an option available to you based on the quality of your Render output. To see examples of response curves, go to this link. The “sRGB", "Gamma 2.2" and "Gamma 1.8" are applicable for most displays that either use sRGB or simply apply a gamma of 2.2 or 1.8. Octane also has response curves that reproduces the rendering neutrally on a normal display. In fact, you "may" not even need to use the 3rd party compositing tool. You can take advantage of a number of response options for the render output and see them instantly in the Live Viewer. Measured camera response curves can be selected from here.
you usually want to apply the custom LUT last, but there might also be 3D look-up tables for linear input data in which case you might want to apply the custom LUT first. Typically, 3D LUTs are defined for sRGB input values, i.e. This defines the order in which the Response curve, the Gamma and the Custom LUT is applied on the scene. If some scenes have more exposure, this option can compensate for excessive brightness. This reduces burned out highlights by compressing them and reducing their contrast. Exposure has no effect on any of the render layer passes. Smaller values will create a dark scene while higher values will brighten the scene. Used to enable or disable the camera imager.Ĭontrols the exposure of the scene. And the best thing about it is that you don't need render time for the effects here. This is where you'll express your artistry, your creative side.
For example, when you make a bloom setting for your picture in the Post section, you can be sure that any compositing software will not be able to reach its quality. It is a very useful tool and once you are used to it you will never give it up again. From here you can manage the beauty of your final picture like a Director of Photography.
As you can play with many settings on your camera, you can also control your picture with exposure and gamma adjustment play with saturation, use prepared movie logs, create vignettes or make white adjustments. Think of yourself as a Director of Photography again. With the help of these tool you can improve your picture quite nicely.
The best way to describe this feature is actually Octane's mini-compositing Tool.
