Ravens Lighting Plates Analysis.

Sophie has sent me the lighting plates from the shoot and I have analysed two of the plates. Here are my analysis sheets:

Shot analyses and where I would place the lights if I were implementing a 3 point lighting scheme.

I broke down the shot regarding the light sources and then placed a 3 point lighting system in.

At first when it came to analysing the shot above, I was slightly confused as to where the sunlight was coming from. This is because the shadows are quite misleading when looking at this still image. I had to go back and watch the QuickTime file in order to determine what shadow belonged to which moving object. In addition one particular burn spot made think, is the sun high or low in the sky? But when diagnosing the shadows the answer was obvious- the sun would have been quite low in the sky when scene was shot.

Sophie contacted a friend who works in the CG industry, and a technique that he talked about was using “lighting balls”, you put these in the scene that you want to video and you can gather all your lighting information from there. This seemed like a weird but interesting method, and as it’s an industry standard, something worth looking in to, here’s what I found:

“It can be useful to shoot a chrome ball or grey ball in the background plate (as a separate take). The chrome ball will show you all the relevant light sources, both direct and bounce light. The grey ball will also show you lighting cues and is useful for 3D crew. They can put a 3D ball in next to it and adjust their lights until they match the real ball.”


“It’s also useful to shoot some wide shots of the general scene during a take to show the light sources and general stage setup. You may think you will remember details but weeks after the shoot it’s better to have a pictorial record”.

Researching these areas will help us use a process of elimination as to what method to use when lighting the scenes and will allow us to develop a work-flow for this project. Sophie will go up to London and do some more filming using the spheres so that we test and see if this is a viable option. What I will do as well is go up to london with her, and take some photos of the scene, this serves 2 fold- reference of the general scene to show the light sources and secondly to take some panoramic shots and make a HDR Image as there is a lighting method called Image Based lighting, which could potentially be used and perhaps reduce the amount of manual lighting involved. Further more using a reflective sphere will capture a fisheye view of the environment and we can use this as a HDR image.
