Lighting Tutorial Week2 : Image-Based Lighting (IBL) Setup

Part1 Nuke

Inspecting the source image files

Matching the overall pixel value of the targeted area

Separating the HDRI into Hi / Low pass , North / South Dome

The benefit in the troop map is that we we can draw a straight line quite much more easier in this kind of projection.

I followed the steps to open nuke, because I had not used this software before, and I found that even if I replaced the path, I did not display the correct image. Emma and I both had problems. Later, I found that the window displaying the image was not updated. That is to say, if I select the correct node and press 1, the corresponding mode image will appear.

Press 1 to refresh the picture view of the node

Ctrl+shift+leftmouse button+drag — draw the selection on the image

move the mouse to the line and press ctrl it will show the yellow dot to adjust the line

Tab — add the node

Exposure node — to match the brightness ang chage the colorspace to stops

press up/down arrow to increase or decrease the value by 1

press right / left arrow to increase or decrease the value by 0.1/0.01/0.01

Multiply node

Press 1 and 2 — swap the picture

press this button to make it darker or brighter

copy the path and paste in the node port to see the final eddect
