Vray Frame Buffer options

Hello. Today accidentally discovered for myself tab in the render window (vray frame buffer) under the name "use colors curve correction". Information on the Internet it is very small and only on English-language websites. With this magic options perfectly adjusted the intensity of materials, general lighting and saturation of the shadows. A similar post processing in Photoshop. The question is: If we move the curves of this option - if the gamma is changed to the output? Will the printer print render correctly, as it does with the range of 2.2. Is this option is not relevant and it has been ignored, at times it does not have the information?

Curves - it's great. Information about them is full, but not over the v-ray 🙂 tool actively and with great success used in 2d-graph, the same photoshop. You can read the relevant chapter of the book Kathryn Eismann "of Photoshop retouching and image processing." The book is on the Internet in the printing quality. Gamma (gamma correction) - a feature that characterizes the distribution of brightness. So yes, we can say with a great stretch that you adjust the gamma locally. gamma file operates globally and does not change. The rest of the workflow remains unchanged (save the file, etc.). you do not explicitly print directly from Max. so open your image in post-processing program / print and watch 🙂 if you do everything right, everything will be fine 🙂 the ps digression: general gamma Max - is, in my opinion, is quite conditional purely internal maksovskaya thing. Save and continue to work with you all the same range of 1 when saving a file in Max and 2.2 in the default settings, and new windows MacOS (in the old 1.8)

Ilya_sp, tell him I need otrendit -75 sequence of frames. In the Render somehow all is not very clearly requires minimal post processing. I can do all the right curves in the frame buffer (not to handle all of the 75 frames in Photoshop), but it is necessary that these are my curves in the post preserved in the output. The essence of what - Rende one frame redaktiruesh curves are stored in the hand - all saved with the editing. A render of the sequence is obtained without treatment persists. How can I do so that when rendering the animation curves in the individual frames in the frame buffer is stored together with the image? I do not know whether written clearly. : |

To be honest, I just take actions in Photoshop. I'll take one shot, record a sequence of actions, then apply the sequence to the entire folder. of shortcomings: I usually render in 8 bit and render must be sufficiently close to the final image. Curves also Vire work, as I understand it, in 32 bits per channel. of the advantages: all the tools of Photoshop. the same unsharp mask. Convenience (habit) work 🙂 but, in principle, in all viree relatively simple: you put framebuffer "save separate render channels" in the settings, set the path. alpha can be turned off if desired. a great way to save the set, in principle, nowhere is not necessary (or set, but the version will remain in it without correction) curves are applied in real time, ie, if you podvinesh them, they will be applied to all of the following frames. of the drawbacks: Framebuffer in this case can not be disconnected. ps if anyone knew: ext. put points on the curve with a pinched ctrl.
