The profile spot is so called because it will project a profile of whatever two-dimensional shape is placed in the gate runners; and that profile can be projected to any required degree of hardness/softness by movement of the lens. A mask for use in the gate is known as a GOBO and because of the intense heat at this point in the lantern, gobos must be made from heat resistant material.
Moving the lens to adjust the edge quality also produces some variation in beam size, and so alternate adjustment of the shutters/iris and lens is often required to achieve the best performance from the spotlight. The development of subtle diffusers, such as Rosco 119 'Light Hamburg Frost', Rosco 132 'Quarter Hamburg Frost' and Rosco 140 'Subtle Hamburg Frost' allow lenses to be set for a hard edge and then softened with a filter. This is faster than softening with lenses, and makes more efficient use of the spotlights optics.
Most profile spots also have an adjustment allowing subtle changes to be made to the positioning of the lamp within the reflector. This allows the beam to be finely tuned between peak, where the centre of the beam is more intense, or flat where the beam has an even intensity.
Building Cues. Then, use the record button after you create each look you need, building the cues of your show- be sure to write down what cue is what in a spreadsheet or the columns of your script (in pencil), if you’re working a theatrical-style show. Finding a great wedding ceremony script can be a real challenge, especially if you are performing a marriage ceremony for the first time, and writing one from scratch can be nearly impossible without the experience of a professional officiant.At WeddingOfficiants.com – The Wedding Officiant Directory, we’ve been working with engaged couples and professional wedding officiants for more than.
The shuttering and masking devices in profile spots convert a lot of the unused light to heat and so shutters should be used to trim the beam edge rather than cut it down to size. This means selecting an instrument with the appropriate lens for the throw distance from the stage. Modern fixed beam profiles are available in beam angles such as :-
- 19deg - projected beam diameter will be approximately quarter of the throw distance
- 26deg - projected beam diameter will be approximately half the throw distance
- 36deg - projected beam diameter will be approximately equal to the throw distance
- 50deg - projected beam diameter will be approximately twice the throw distance
Lights, effects, action! Stage lighting is a critical component of any live performance, whether stage, concert, dance or stand-up that evokes mood and unifies the production. The lighting designer creates the effects and communicates their execution to the technicians with a cue sheet, the script for the lighting sequences. The cue sheet lets the technicians know how and when to produce the effects. It is written after all the lighting has been hung and the technical rehearsal has been completed.
Open your spreadsheet and mark six columns with these headings: cue number, act and scene, page number, cue point, description and time.
Label the cue numbers under the first column. Start with the number one and continue listing subsequent numbers based on the amount of effects in the performance.
Type the act and scene where the lighting effects occur under the heading of the second column, such as Act 1, Scene 1. List the exact page number where the effect appears in the script under the third column.
Write a short sentence that gives the signal for the effect in the fourth column. This should be a precise action. For instance, in Act 1, Scene 1 of 'Hamlet' the cue for the lighting may occur when the character Bernardo enters.
Write a short summary of the lighting effect under the description column. In the above example from 'Hamlet,' the description may read, 'Stage lights come up.'
Type the length of the lighting effect in the sixth, and final, column. Suppose you want the stage lights to slowly fade in for 30 seconds when Bernardo comes onstage. You would list the duration of the effect in this column.
Tip
Write your cues in simple language and be as precise as you can. Choose a sans serif font in a larger size for easy reading. Print out extra copies of your cue sheets for the technicians and stage manager. Things sometimes get misplaced during the run of a performance.
