We have designated aisle lighting which must be operational, though.
Our newer cinemas use four stage dimmers so that we can have on preset for the ads and trailers and then a slightly darker preset for the credits. In operation though, we only seem to use one of the presets.
Jesse, you weren't asking about the level for trailers, you were asking about feature film levels? Is this correct.
I am wondering if anyone drops the house lights out completely during trailers. This was a practice in one theatre, and the effect was great - trailers how they are meant to be seen
Frank
Frank.
If ambient light levels are too high, contrast within the cinema can be greatly reduced and the reason I'm there -- to watch the movie -- suffers. If I'm late and kick my knee on the back of a chair because it's dark, that's my fault. I'd rather watch the movie in the atmosphere of the cinema anyway, much more enjoyable.
Aisle lights, special directional lighting and such can address the safety issues while still allowing the presentation quality we want.
One of those "compromises" we all have to make might be mid-level lighting during trailers in front of the main feature, and during the credits when 85% of the audience starts to leave anyway. These things I accept and agree with, but for the feature I'd like it dark. The trailers and such might be okay, but I am there for the movie when all is said and done.
Normally, the house lights stay off until the end credits start, when I turn the sides up to about 60%. The adjusting of light levels is completely manual so I can do it any way I like, as slowly or as fast as I want, and to just about any level in the range.
When we still were a commercial theatre, I used to run trailers in an almost dark auditorium, or gradually darken the theatre during the first theatre, so slowly that nobody noticed the actual dimming of the lights which was pretty cool if done with enough patience.
Unfortunately, my theory was put to the test. Someone used to work here that insisted on turning the overhead lights all the way off. Several people fell. The first two were young people. The last one was an elderly patron, and wouldn't you know, this guy finally realized he had a bad idea.
I've never heard of a patron falling when I've run a show, with the lights at a mild glow - much less light, by the way, than the typical multiplex. I think lights in most cinemas are way too high.
I use a higher light level during previews. Credits light level is all the way up unless there are images in the credits.
Another important issue is the amount of stray light hitting the screen, reducing color saturation. I corrected aisle lights at my cinema that were throwing light onto the screen - and turning off the overheads isn't going to help that situation! But that's a topic for another thread.
Now, I respect that some of my colleagues might have different ideas about this, but I would never be a part of it, never. If it was company policy, I'd probably quit. Well, either that, or the house lights would malfunction during every single show. There's something very wrong with an auditorium that requires the house lights to be on during a show. Aisle lights and such should be enough, if properly designed.
I can stand lights when I watch TV, with compensations such as peanuts and a fridge with a six-pack, or a remote to fast forward the boring parts. But in a theatre, never.
If you can cast a distinct shadow on the unlit screen, the lights are too bright.

The end credits were running, but the ceiling lights were down (at the level as when running a show.) All asile lights were working (a light on the seat standard shines on the steps; one on the left, another on the right, as you walk up.) In other words, the lighting was exactly the same as if we were running a show.
The film was a basically true story; "The Newton Boys" (about bank robbers in the 1930's.) While the credits are running, they show an interview with one of the real Newton Boys on the Johnny Carson TV show.
The operator had waited until the interview finished- then placed the light cues on because he noticed people staying to watch the interview.
So, why did we lose when the lights were the same as during a show? After all, if she tripped during the show, it would have been the same, right?
No. Because their sharpie laywer asked for a copy of our own policy manual that simply stated; ".... put 'lights up' cues on when the credits start.."
Although we did put cues on, the laywer said we violated our own policy. (He said) the policy didn't say anything about action going on on screen; The policy manual said to put cues on, which we did not do properly. (They were on too late.) He also said that we should have known to bring the lights up right away when "large masses of people" leave an auditorium.
So the jury awarded them some money (not much; less than $20,000.) The jury probably thought they were making theaters safer by handing this verdict, but this is what will really happen:
1. Turn on every light in the auditorium at the first credit. This is what we now do, because if we don't, (and someone else sues us) this case provides a "prior precedent" meaning it will be even easier to get money from us. Normal customers lose out seeing a nicer show.
2. Never write a policy manual, or issue a memo about operating procedure. No one can hold you to a standard if there isn't one.

Regarding the high level of stray light on your outdoor screen: Can you work with your security and lighting people to put shields on the lights, so they don't shine directly on the screen? Many times, a simple baffle lets the light shine only where it's needed, and not on the screen.
The same applies to EXIT signs in an indoor theatre. Safety regulations often mandate the location and brightness of the signs, but a simple shield would keep the light off the screen without compromising safety. Unfortunately, I've seen too many theatres where the edge of the screen is bathed in light from the EXIT signs.

About the theater lighting...in my opinion it highly depends on the movies...During adult movies I keep the house lights on very low and during kids movies I usually keep them up a bit high because we tend to have kids running around in the theater. The kids and parents usually don't notice or mind the lights being a little higher, I've actually gotten compliments on keeping them higher for the saftey of the children.
Some of the newer EXIT signs that actually form the letters with strings of LEDs are fairly directional, shining most of their light directly forward, rather than in all directions. Some new directional fiber optic technology is also coming onto the market.
Also, the technology used to make directional traffic signal lights might be applicable. Not sure, but either a fresnel lens or a fiber optic faceplate is used. I'm sure you've seen the traffic lights that are only visible from one lane, to avoid confusing drivers in the other lanes.
What about just masking the edges of the screen so it doesn't reach right out to the side wall? Then you could use a black baffle to shield the screen from the sign, without casting a shadow on the image.
Of course for stairs, the tiny LED path lights usually satisfy the inspectors for outlining the tripping hazard, yet don't throw much light into the auditorium or on the screen. Use the minimum brightness that still maintains safety.

There are little tubes of green stuff inside them that spell out the word "EXIT". They don't use any electricity or batteries. You don't have to test them and they are supposed to last for 100 years or something like that. (Actually whatever the half life of tritium is, I guess.
)
The only, "very minor", thing is that they are radioactive. There are warning lables all over that back of them that say you have to dispose of them in an "approved" landfill.
Just don't open them up, I guess.
Aaron
Just to let you guys know...I already have the lowest watt bulbs I can find in the exit signs and use the LED track lights on the stair ways. I was there watching a movie tonight (on my day off) in the theater with the lighted stair problem....I DROVE ME CRAZY!! I need to find a solution for that one.
But really, thanks guys!

Kodak and film labs use LED path lighting in many of their darkroom areas --- paths and tripping hazards are easily outlined, with minimal light to fog the unexposed film. And most commercial aircraft now use LED path lighting to guide people to exits in the event of an emergency.
Does anyone know if the codes allow maintaining EXIT signs and path lighting in theatres at a very low level during the show, and automatically raising it to a bright level during a fire alarm? EXIT signs must be bright enough to be easily seen, even through smoke.

Can't one of the F-18's based at Tindal use the security lights for night-time target practise?
Just be glad your outdoor is not at Amberly, then you would have something to complain about with all those F-111 dump and burns causing the screen to glow red!
Only way to run a movie is with all house lights off. We have even dimmed our aisle lights in some theatres as the light fell on the screen. On my trips to NYC at no time has any theatre I've visited completly extinguished the house lights.

Even in non-palace silent-era theaters (not nickelodeons), there was often a light circuit of bulbs left on at all times in sconces, chandeliers, or coves.
I think when houses were that large (small non-palace theaters were larger than most multiplex auditoriums today) it was not so distracting to leave wall sconces 'way over there at half, or rows of those old-fashioned hooded aisle lights with 10 watt incandescents shining straight down. I like the looks of the old incandescent aisle lights, but they sure would be unneccesarily bright & distracting in tighter modern theater designs. But that's about what the light level was in theaters of typical size during the roadshow heyday, in the 50s, 60s, & early 70s.
I feel that it helps define the perimeter of the room and helps keep people from bumping into the walls, if you know what I mean. Especially in those theatres where the Soundfold is a dark color.
A lot of people go right along behind me and turn them all the way down again, but I STILL think my way is better.

(I personally like a tiny bit of light over the seats, as it adds to the "group" feeling of the audience).
An interesting anecdote is that I once worked at a theatre that had an illuminated clock just to the left of the screen. It was great when you were keeping track of the time watching a bad movie, but was a constant distraction to the audience during a good movie, ruining the "magic" of the silver screen.

On the ceiling lights, I really do not like to leave them on even at a "glow". They must be fairly bright to begin with to make any real difference in the illumination of the auditorium and for people like me who wear glasses, if there is a tiny smudge on them, the light catches it and is an incredible distraction. Ceiling lights should go all the way off. Side lighting is fine.

They don't seem too bad. The red light keeps your pupils dilated, and the low light does not seem too distracting. Probably another example of where the old-timers knew how to do something better.
At the theatre I plan to open, the curtains will be kept shut until showtime. When showtime comes, the lights will dim down 3/4 and the curtain will rise. The lights will stay on 3/4 until the trailers are done. As soon as the actual movie starts, the lights will be right off. At the end of the show, the lights won't rise until it says "CAST" on the screen. The curtain will finally lower after the film has run out of the projector!
We will also introduce shows with a spotlight on the bottom center of the screen. An usher will come up at 5 minutes to and say welcome to this theatre, blah blah blah!
As for Famous Players,
The lights are soo low when you enter SilverCity St. VBital's auditorium that seriously, there's no point in even having the lights on!
A women tripped inbetween the aisles at some SilverCity in ontario in 1999 and broke a rib or something
!
Famous Players had travellers insurance so, the old couple couldn't sue, but now they leave the lights on until the actual movie! It sux!
On the curtains, the traditional manner is for the screen to never be "blank". Waiting until the film has ran out of the projector defeats the purpose. They should completely close the screen on the last frame of credits.
They were typically neon lit, as someone else noted. The one we have at our shop has a violet tube in it. Around the face of the clock would be some form of advertisment. In our case, it is for what was a local pharmacy.
They typically augmented an Art Deco's decor.

An interesting anecdote is that I once worked at a theatre that had an illuminated clock just to the left of the screen.
Clocks seem to have been common installations at smaller & "neighborhood" houses from the teens up through the 50's (& of course often left there if the theater survived past that time).
You can sort of see why they'd put a clock up there - so people wouldn't stay too long & not forget to leave! With continuous, grindhouse performances, people would be coming in & staying an indefinite time. The clock would make sure you didn't lose track of time & left, the sooner the better for the theater. Hey, after you've bought your ticket, from a business standpoint, the next thing you need to do is leave.
I read a wonderful reminiscence of early silent-era theaters written in longhand by a senior citizen who recalled that during the summers of her childhood, the place to go was to the movies, & as the day progressed the houses would fill up with children. At one house, every now & then, the manager would come down front at about the time the evening crowd usually began to arrive & shout "Would all the kids who have been here since two o'clock please GO HOME!"
There are some pictures of silent-era front ends at
http://members.nbci.com/saenger.1/foh/foh.htm
You can see clocks at Woodley's Optic Theatre & the Savoy Theatre.
And one that I've gotten tired of cleaning up, but here it is all rough anyway, there's a clock at the Family Theatre
As you can see, there were worse things than sitting behind a post back in the day.
You could be sitting behind a tree.
Two of these lights were about 1m from the top of the screen, and would have made screenings awful, if the inspector hadn't agreed that these could be shaded - so I did, with four hand crafted large painted drinks cans! these saw stirling service for about ten years, when a new Inspector wasn't happy with the level of illumination, and insisted that these fittings be removed completely, and be replaced with a new secondary lighting fitting on the back wall of the auditorium, that would only come on in a power failure - he happened to dislike going into lit cinemas himself, and was happy that the two exit signs over the doors at the back of the auditorium gave enough light to find ones way out under normal circumstances.
He did however insist on extra fittings being put in in our other auditorium, one of which was going to be above a door on the stage that lives behing the screen when we screen films in there - after it was pointed out that this would prevent film shows in this auditorium, he permitted this fitting to be one that we could turn off when we didn't want it on, which is of course most of the time
I also ended up with two fittings on a balcony which isn't used for films, as its at the same level as the projectors, and people would manage to get in the way of the picture, these were illuminating the screen a treat until I placed some Neutral density lighting gel in them (Lee Filters 210) which reduced the light level a treat, and so far hasn't received comment from the inspector...
As to leaving the houselights on during a feature - the only time I had to do this was for a screening of 'The Nightmare Before Christmas' which had been organised by Film Education, an organisation over here that arrange film shows for schools, with back up information, anyway I had a cinema full of seven to eight year olds, some of which were scared by the movie, and wouldn't watch it without the lights on (although at about 30%).
Normally I show trailers with the houselights off, and leave then off until the cast list has finished, when I'll bring them up to 25% for the rest of the credits, then fading to full, with tab warmers as the tabs close
>>On the curtains, the traditional manner is for the screen to never be "blank". Waiting until the film has ran out of the projector defeats the purpose. They should completely close the screen on the last frame of credits.<<
Just saw this and had to comment. I agree that there's no point in waiting until the film is out of the projector before closing the curtain, but neither do I like closing the curtain too early.
For me, the perfect closing of the curtains is to have them _almost_ touch the last of the screen credits while the curtain spotlights light up the last lines or the company logo (or whatever that is last) and--of course--the piece of the screen that is still visible. The effect must be that the spots fade out the film exactly at the same moment when the curtains close on the credits.
I hate those smallish left- or right-aligned end credits, especially when the feature is in Scope, because having a large curtain "cover" them too early is ugly as hell and pretty much destroys the last of the film for whatever audience that is still watching the film.
Our curtains take about 28 seconds to close, btw.
Festival screening rules, however, are somewhat different. The curtain is to be completely open (and all lights off) by the time the first picture appears, and the last projectable frame must clear the screen before the curtain starts to close. They also take a dim view (pardon the pun) of bringing up the house lights at all, during the credits.
There is an interesting effect to dimming the lights then opening the curtain, from an audience point of view. Squeaky rollers on the curtain tracks make the audience wonder if a large number of mice have been spooked, and are about to start stampeeding toward the back of the auditorium.
The end credits must be showed in a dark auditorium, according to the festival rules, though, and I respect that rule as long as the city officials say it's OK. Most of the patrons stay through the credits, in any case, and nobody's yet broken anything as a result.
Well, as far as I know, at least.
