This is a video following Stu Maschwitz (Sin CIty) working through four different color grading exercises which emulate the look of movies such as Transformers, Terminator Salvation, Taking of Pelham 123 and Where the Wild Things Are.
Often We see folks on the forum asking the question - "How does so-and-so get this kind of look?" "How can I get this look?" This video is a glimpse into a master's train of thought and is really inspirational. He performs his color grading in After Effects, but the same principles apply to adjustments in LR, PS, etc.
Take a look, I think you will enjoy it and really start thinking about visualizing your final image and lighting/shooting the image with the final look in mind.
