      I was watching the showConfidentialCut Down. It is a series that airs after Dr. Who.It is basically a behind the scenes of the Dr. Who set. I am interested because of the special effects and things like that.I would like to ask how the lighting is achieved in this kind of thing.

      Around 2 minutes in, you see the ‘nuclear’ scene where they arehesitantto go into the reactive room. He is standing in front of the door and it looks pretty normal. Then you see it looks more ‘spooky’ and dark. What is done in post to achieve this?

      Any tips are greatlyappreciated.

      Thanks.

      Could it bethe scene you are talking aboutis camera angles? I see a 2 camera shot. At 2:00 the camera is looking away for the radiation door over what will be the doctor’s shoulder as the two come running in, when they get to position giving a normal veiw and the next overJack’s shoulder looking at the door with the ominouslight in it.

      Continuity issue… I notice around 2:16 that in Jakc’s angle Jack has his shirt off and is straightening his suspenders and the nextveiw at the doctor’s angle he is removing his shirt and then straightening his suspenders.

      Evan,

      Looks to me that they used some in scene color lights to create the dangerous mood (red gels) and of course there is color corrector to enhance the shots later in post. In any case is advisable to obtain the best from the actual shooting and not blindly put our hope in post resources. Many films waste money in post because lack of planning.

      Hi Evan,

      I think you’re talking about the section between 2:25-2:29 where we see the final cut of the scene. It certainly appears that they did not light this scene to achieve this effect.

      I assume when you say “spooky” you’re referring to thecontrastwith the yellowish tint and orange highlights.

      In the previous scenes from 2:00-2:24, they are cutting between the behind the scenes camera that include shots of the actual production monitor that don’t appear to indicate any type of orange tinted lighting scheme except alight tint of orange behind that doorcomming from the reactive room.

      There are numerous ways to achieve this effect in post but before we discuss that, I would like to fast forward to the reactive roomscene at 2:44-2:54….

      It starts with the behind the scenes camera and immediately you can see that there is an orange lighting scheme unlike the the earlier scene we’re talking about at 2:25.

      If you continue on from 2:58-3:13 they will show the behind the scenes camera and if you look very very very closely, you can see a man in the background messing with a lighting gel and you can see what appears to be gels over the light….

      If you look at the final cut of this scene between 2:55-2:58 you’ll see that the tint of orange is much thicker than in the behind the scenes cameras…since they arlready lit the scene to achieve the desired color scheme it seems all they would have to do is makevery basic adjustments to thelevels and contrast with the apropriate filters that are included with most post production software.

      But to achieve the color effect of the the earlier scene at 2:25 they more than likely used many layers in a compositing program…each layer would have a different transparency value or transparency mode like additive, screen, overlay, color dodge etc, that will give a different effect. You can also create matted layers that will allow you to apply effectsonly to specific areas of thefootage….that might explain the orange tint on his neck and face whilemaintaing a significant contrast withthe yellowish tinted background. that was also added.

      As I noted earlier, there ISthat light orange tinted lightcomming from the reactive room and it’sfalloff would help considerably in controlling the color highlights within the matted layers.

      There are easy ways to do this and there are complicated ways that usually give a better result….There is no tutorial on how they specifically achieved this, but here are links to some tutorials that will help you understand some color corection techniques.

      just to make a correction…..when I said transparency mode….I met transfer mode.

      Also, the links I gave you deal with color correction within AE, however they will also give you an understanding of working with the tools and transfer modes within other NLE’s.

      Regards
