Outdoor projection - During the day

[Dodgecaliber]

Title says it all!

 

Been told that a client wants the rear of the building projected onto between 12pm - 4pm at the end of October.

 

Now I know it's going to look ****, but I've been assured that clarity is not important. The images need to run off a laptop and all the information that I've got is that the image is something to do with memories and even if it is little more than a shadow on the building that is suffice.

 

The building is nearly 300 years old and im not allowed to rig anything (falling masonry a few weeks back) so an LED wall is out of the question. The projection surface is light sandstone that is relatively smooth.

 

Throw is variable however 13m at most. Image size is unknown at the moment, however it's not expected to be huge.

 

My guess would be a 10k projector but having not done too much of this, I don't really know what I can get for the little budget they have.

 

The projector can either be located in a van or temp structure it makes no difference to me with power direct from the venue.

 

Any ideas what would do the job and where I can get one in Glasgow/Edinburgh?

 

I know it's not going to look pretty but im paid to make things happen!

There is no way this is going to happen, it will be completely invisible unless you go for a tiny image or you happen to get an extremely dull day. You just can't compete with daylight.

The only thing that might be slightly visible is one of the large format slide projectors. But obviously you can't do that from a laptop.

I'd speak to the people at http://www.projecting.co.uk/ETC/home.html and look into their PIGI large format projectors (but obviously you couldn't use the laptop) ... competing with daylight I think is still impossible though.

Been thinking about this, the only thing I can think of is to use a floor standing transparent type of LED screen such as the G-LEC one (now LC panels from Martin).

 

I'm all for trying to satisfy client requests, but in this case anything with a video projector is just going to lead to disappointment.

There was a post about 6 weeks ago when someone wanted to colour a building with light during the day. I did some BOFP calculations to illustrate just how much light was needed.

Email just recieved from the client, they are now thinking that lighting may be a possibility after persuading them that a projector is a no no.

 

Any ideas what the post was called so I can have a look at these calcs?

to cut your search short I think the calculations worked out that you would need something roughly the size and power of the sun to compete, bigger if you want a saturated colour. There is a reason why outdoor stages are shrouded. To provide a dark environment as possible on stage so that lighting can be introduced.

we've managed to do some outdoor projections and

got a decent image but the image size was only 16x6ft

using 2 7K projectors so it is possible but not easy.

 

Position is really important as well as black out between

screen and projector and the screen was the type used

in shop windows.

 

a throw of 13m will not work at all.

You are talking about rear projection onto a proper screen, which is possible in daylight if carefully arranged.

The OP was wanting to do front projection onto a building, which is not possible at all in daylight.

for the record, we set up our big sanyos for hire by shooting against the rear of our white double doors, when the doors are open, the image falls on the building the other side of the street generaly 4- 5 m across. At noon with no cloud there is direct sunlight onto the wall opposite and you can just about tell if the projector is on if full white. by mid afternoon you can see a test grid and focus it, itsactually be possible to see an image ok if its cloudy , by late afternoon its fairly decent. That said we are in Scotland and its often dark and grey, but then so's the poster.

 

So if you absolutely had to , as long as the wall faced the right way , ie sun behind and you didnt want an image much more than 4m across, it could be done albiet with a pair of 15ks or above, and even then it may be visible at best.

 

We also last month did a advert shoot that involved shooting with a projected image 22m across / 8m high onto a sandstone building. This was shot not in darkness but around dusk with a load of 4k film lights backlighting the building as if it was done in darkness you have nothing on the actors in the foreground and no scenery in the distance, so effectively was shot in daylight. Reading all the posters that went before youd expect this to not work, but it looked great and on camera it looks daytime not twilight. That said we did do tests the week before and tweeked the footage to suit, used the most efficient lenses etc, but this wasnt stacks of christie 35ks, just 2 sanyos . so if you are still game, borrow a unit and do testing, then you can either discount it completely {probable} or work out how to make the best of it....

Where is the venue? I am based in Edinburgh and we have loads of 7k's and more than a couple of 10k's. Will try on Friday with 7k's and 10k's on opposite building at times you mentioned. And will give you an honest opinion.

 

All the best
