1. What Is considered midthrow?
Projectors that have Zoom capability all have a defined range in which they can be set furthest back or closer in and achieve a maximum / Minimum sized image.
The Epsons and Pannys both have the largest span of distance between those referenced points...the Epson's taking the Top Honors.
Epson 5010 w/150" Screen.
Available Throw Distance span to achieve Image size: 14'-7" to 33'-1" (...over 15' !!!)
Foot Lamberts at all three Throw points:14'-7" 23fls .... 19'-11 14fls .... 31'-3" 9fls
Epson 6010 w/150" Screen
Available Throw Distance span to achieve Image size: 14'-9" to 31'-5" (...over 15' !!!)
Foot Lamberts at all three Throw points:14'-7" 36fls .... 19'-11 22fls .... 31'-3" 14fls
Most DLPs have " 2-3'
" at most, with some designed to be "long Throw" and some short Throw" PJs to compensate.
But with DLPs, the far shorter Zoom length means there is almost no difference in Foot Lambert specifications when moving "in or out" from Mid Throw.
Obviously, that's not the case with the 5010 / 6010
But "Mid Throw" is a Industry standard that was set years ago, because:A.
At the extreme "Front End", a distortion of the image at the edges, and a loss of brightness at the edges often occurs because of the Lens's own fallibleness in design/Mfg. Also, as in most excessively Zoomed imagery, Pixelation or Artifacts become more apparent.B.
At the "Far End" it's all about the loss of Luminosity over the distance. In a LCD, that can be very significant.
1080p resolution and Mega-contrast PJs with 2000+ Lumen Light Engines have set aside most concerns, but PJ's Lens Focal length/Zoom specs are still mightily important in many cases, and can often restrict installation / screen size choices.
My general rule of thumb is if I got Lumens, I'm a'gonna use 'em...not waste 'em. So I usually mount my PJs at 10-15% above Minimum Throw. I like the brighter, contrasty Epsons because if that's not possible, Mid Throw performance is still well within my accepted limitations, and under most circumstances, whatever size screen I want...or is desired, can be accommodated. In the long run, being able to effectively color calibrate a PJ, and utilize it's low lamp mode to further improve Contrast...all without losing the dynamics of a image, is what real front projection performance is all about.
What was the question again...?
2. Is blackout cloth a smooth material?
White/White Opaque BOC has a Cloth Weave side and a smooth Vinyl Coated side. The latter is what is used most often, primed, sanded, then sprayed.
DIY route looks very attractive right now.
Tends to, especially when there is a couple $
worth of difference.
Let me invite you to jump over the DIY Screens, where a DIY Screen build won't clutter up this PJ dedicated Forum. Just author a new Thread and they will come....to help you build it.
Just so you know... My carpentry skills are ZERO.
90% of wannabee DIY'ers come in saying the same thing. If DIY Screen making was really all the difficult, the Forum for it wouldn't exist. But it's not, and the end results more than justify the means.
Don't worry, we'll have your back....iffin' you let us get behind you that is.
I have made up my mind to paint the room at the lower floor with a dark grey/black gold theme. I will be looking at carpets next week, I got to work weekdays =/
I'm going to get a crash course on CAD so I can draw you guys out something.
Focus.....FOCUS! Don't get too far into "design" unless the room, and your needs / expectations demand it. Be it Purchased or FIY, projects like this where someone new delves too deep too fast/soon often result in confusion and "brain-dead" symptoms.
That said, in a new DIY Screen Thread (...and perhaps a Sister Thread in Dedicated Theater Design & Construction...) you can publish specific questions and get specific answers. General queries usually bring general responses that range all over the Map, and while a great many are valid, and some even spectacular, you have to get really fortunate to have one match up with your criteria exactly. If not, information overload is a very real danger. Trust me on that. I've seen it happen time upon time. It's never a pretty sight, ad decisions made in frustration lead to dissatisfaction.
But I'm just assuming to get the same brightness and performance I would have to probably have to go on to super bright triple DLPs
. JVCs don't seems to have the lumen output, and neither does Sony. Maybe the BENQ DLP, however, I'm worried about rainbow for more sensitive viewers.
Right, Right, and your right to be concerned about RBE. However with the newest 5-6 segment or Dual Color Wheels in a few Single Chip 1080p DLPs, that's getting to be less of a concern as we go forward. But there is still that darn 'ol Throw limitation. It sucks the BIG BONE.
I also just recently noticed people people have tried using 2 projectors, doing so can also improve contrast and black levels. Off course I know its not that simple to just throw it together. But I just want to consider all options and understand everything.
I ran into the 4k double projector thread O.O
You don't need two PJs.
Even on Low Lamp, a well calibrated PJ like the 6010 will produce Interstellar Black levels and brilliant Whites & Color simultaneously on a 150" diagonal 1.3 gain screen
I love scalability if possible. All I need to do i save a bit more since DIY would save $$
Outboard Processing gear becomes a lot more of a possibility if you have some spare cheese left to dole out.
I'm still gathering info.
Let me know about the paints MM
Post a Thread...or PM me. Check my AVS Profile "Statistics" for my various Threads for a purposefully directed DIY Primer. I can see how close to a 5010's price I can nab a 6010 for and PM you as well.
Exciting stuff, this "Big Picture" is.
