One of the great things about LuxRender is the incredible realism that we can achieve by just changing a few settings in Blender 3D. Sometimes, however, an image needs small changes in brightness, color, or lens effects, which would make the overall scene more realistic. If the renderer is made in a software like YafaRay, the best option to change these settings would be an image editor or even the use of composite nodes in Blender 3D. With LuxRender, these two options could be a problem because it would require the image to be rendered all over again when something needs to be changed.
To solve this problem in LuxRender, we have a side pane that allows us to change several options to increase the realism of an image on the fly. Any changes made to the image are immediately displayed in the render window.
These are the panels available at the side pane in LuxRender:
