1.1 inspecting the source image files

Use wooden box as a reference, sample the colour value of this wooden box. Then apply the grading into the other.Separating the HDRI. And Exposure (Color) node and mutiply (Math) node, Remap the image by spherical transform,that we can draw a straight line easier. Then open the nuke script and create the project.

Intro the nuke surface

ctrl + a select all, ctrl + shift Search/Replace window Then can see the image in panel, click and drag to selection, and put it down to the bottom of screen, then ctrl + shift + left button + drag

Then click on Add Mutiply (math) to change the channel to RGB, click on the color picker within the display panel and then you can see all the other controls. Use the same math to change the colors (up and down). Make it match better. Put the color value of the environment into low pass. This makes the whole environment darker than before, and then draws a map to isolate it. Make it a separate map. Use the same method to lower it. This way we can simplify the setup and aviod too much at this point.
