BTW, most do not realize that a Short Throw PJ needs such lumen output to compensate for the degree of light lost as the image passes through the dual Concave / Convex lenses required to create such a wide dispersion of an image projected from so close, and still avoid the distortion around the edges that would otherwise result.

OK....for now, this post will be the last that shows Screen shots showing the performance potential of a re-surfaced Retractable Screen

Mostly, I have chosen examples that show how well Black levels are enhanced...and/or maintained at reasonable levels under ADVERSE lighting conditions.

This first collage shows scenes that incorporate both very light and dark elements, and ambient light primarily coming fom the Window's edges as well as reflections from the left side of the Dormer and the Hardwood Flooring. ( late AM *11:00* with indirect Sun )

Next up are two collages that show pretty much the most intense amount of ambient light ( direct Sunlight behind Screen ) that is experienced.

The collage directly above is intended to show how adversely a reflective floor / carpet can be. In particular, note the washout along the bottom of the screen, with the areas affected being directly above the bright reflective patterns the Sunlight casts on the polished wood flooring. Wlie not making excuses, such situations are extreme and not to be considered workable for almost any screen application. Yet the results shown are pretty livable with, and if a Throw was placed along the baseboard....? No issues at all. cool.gif

The next collage of shots are intended to show the conditions my erstwhile Peers at the same Show opted to (ie; ...had to...) exhibit their Screens / PJ in.

First up...at top right a 120" diagonal Stewart ST130 set a full 6' back into a recessed hole, hit with a SIMS2 Crystal PJ, and at top left a 92" DaLite w/Panny ae7000u in a totally darkened room (3D was showing) where only light coming from the door (when allowed open) was present.

The bottom shots in the same grouping....on the left, an example of the lighting present in my room 95% of the time. No problems with people tripping over themselves or others. biggrin.gif On the left...another shot of the room under full lighting that shows the decidedly "Non-Dedicated" nature of the room.

Next.....a shot that sums up the wonder and approval of almost every Show goer. I gotta tell ya all sumpthin'.....the "Disappearing Screen" act is hugely popular with all types of people....and especially Wives who to that point had / would never consider a Big Screen in a Family Room, but upon seeing a Window be covered, yet be reclaimable upon demand, would say, "Honey, now that's something I could live with!" But even more so, the number of common, everyday individuals who could innately grasp that they were seeing "The Big Picture" in a non-"Tomb-like" environment, and make comment about such...loudly, made my time spent quite gratifying.

alookofwonderment-revealed-.jpg

Lastly.....a final shot of the crowd...with a very absorbed show goer. The one downside to showing CGI Movies? Hearing the wails of the children when the parents say "Get up now....we have to go."

Thanks go out to everyone who followed this Thread. I hope this has gone a ways toward showing / proving that Retractable Screens are indeed worthy of a DIY'ers attention, and they can be made to be over-achievers with a little effort and forward thinking.

Soon to come....135" 2.39:1 SF v2.5 4.0 mated with a Panny 8000 (...or Epson 6020)

MississippiMan, this has been a very motivating thread and an inspiration towards my soon to be finished retractable screen. Thanks for sharing all your tips and tricks and lending a helping hand.

I will be following your progress in the new thread and keep my fingers crossed for an even more detailed strategy regarding masking and setup before painting. (This noob needs all the help he can get smile.gif )

Framing is complete, A/V wiring and Transducer installation today, Sheet rocking on Friday, Screen painting next Tuesday.

Fast tracking everything about this so as to be finished by a week from this Friday. Ambitious? Yes. Impossible? Some would say so.

The pressures on, brook no mistake.cool.gif

Wow! I have been following these threads for a few weeks now and love them.

I am from the UK and bought (to the Mrs disgust at first) a Acer H6510bd for the World Cup. Since it's finished I have mounted the projector on the ceiling and get around a 120" image onto a matt blue/grey wall.
I get some ambient light if I don't use the pull down blind and even then it lets some light in during the day.
I see the threads are dated 2012 and am hoping the paints have come a little further in performance?
Can you please recommend my best option for creating a screen? I am pretty handy with tools so a screen stretched over a custom frame and then painted is fine and so is painting directly into another surface.
Thanks again and look forward to hearing from you.

Mr Brooker,

The latest updated mix is here: The Official Silver Fire V.2 Thread.

Performance is essentially the same, as the basic updates shown were going into effect at the time of the posted effort here.
..........with the exception of the Rustoleum Sterling Silver

One late breaking bit of news....the latest version of the Reflective mix is itself a great stand-alone mix with excellent ambient light performance and exceptional gain characteristics.

The addition of the SF Colorant is suggested when truly difficult to deal with ambient light situations exist, and adequate lumen output is available to offset the darker elements of the SF coating.
Your PJ certainly has the "lumen oomph"...but lacks serious contrast and black levels. SF will greatly improve on those failings. I suggest SF v2.5 3.0

Stretching a very smooth Matte White screen fabric across a Fame and the coating it with SF is a well proven method. We / I can help you scource some good material for an inexpensive price.

Where in the UK do you live?
How big a screen do you envision having?

Thanks for the speedy reply.
The screen will be 52"x92" so hopefully I'm right and it's a 106" screen?
I live in London (Richmond to be exact).
I would prefer the 'making a frame' route as a very dim led backlight would be nice.
Thanks again

Hi MM. I've been reading through the SF threads with great interest. I'm in the London UK area too and am currently considering making a SF screen. Trouble is, some of the components seem to be hard - if not impossible - to source over here.

Anyway, I wonder if you could suggest the best solution for me? My projector is an LG PF80G, full LED and advertised at 1000 lumen. I have it on 'eco' mode to greatly reduce the fan noise and I guess it reduces brightness by around 10 - 15%. In a dark room, I'm very pleased with this bright picture... but I want a screen to use in ambient light.

The projected image struggles a little at the bottom end (even in total a dark room) with solid blacks projecting at around 90%. I'd like a grey screen to compensate for this and still do justice to the whites and colours in ambient light. I was thinking of a SF v2.5 3.0 - but maybe this would be too dark a grey for my LG PF80G to cope with? I would consider reducing the overall screen size (ie moving the projector closer) to get a decent picture.

Any advice would be much appreciated. Thanks.
