How many Dimmer Channels ?
Sun, 22 June 2008, 07:35 pmWith the offer of state funding in WA for amateur theatres, the decisions on what to apply for need researching and some professional advice is required to explain the theatre lighting requirements of amateur theatre groups.
One ideal "Square One" lighting design, (so called because if you put everything back to "square one" you will be able to provide good lighting for any basic production ) is to:
Divide the stage into the nine basic acting areas ie DSL, DSC, DSR, MSL, MSC, MSR, USL, USC, USR.
Allocate two key lights to each area (the McAndless method see lighting links, this takes you to 18 lights from the front. at 45 degrees to the centre of each acting area.
Allocate a back light to each acting area, directly behind the centre of each acting area, this takes another six channels
You now have an ideal lighting design that uses 24 dimmer channels for individual control of each light. In a usual amateur theatre situation, you will have to parallel lights if you have less dimmer channels.
You now need to allow three dimmer channels if you have a cyclorama and additional channels for specials, so the ideal number of channels takes you up to 36, which is three dimmer racks, of 12 channels each, with a channels capacity of 2400 watts.
Any questions ?
Lighting
Sun, 22 June 2008, 11:36 pmAs a beginner in the lighting design game....I am unfamiliar with this McAndless method of which you speak. I've been getting some tips from those who I am setting lights with, but a lot of it is..."Well, I'll see if it looks OK".
I think the problem we have at our theatre it that the bars are too far away from the stage, so the lights come in at too low an angle, causing shadows on the rear wall of the set.
The position of the lighting bars are unfortunately mandated by where the steel beams of the building are to hang them from.....
I have the stage broken into 6 areas instead of 9, as it is a fairly small stage, with 2 lights for each area paired on channels, so the wash uses only 6 of our available 24 channels. We have a mixed bag of lights, and to pair them on a single channel, they must be the same light.
A question for Don.....(or anyone) The back-lights.....would you use them in a standard wash configuration, or only to obtain a certain effect?
I have used back/side lighting, but only for a dramatic effect. i.e. for silhouette.
Also, 24 channels is pretty much our limit due to the available power supply. Until recently, we couldn't run the lights AND heaters at the same time...
