FamMann, if I might ask ...

I just got my Home Theater room painted in a color similar to yours. I have the same white ceiling and white trim that you have. It looks sharp and I got a lot of room-darkening from the gray wall color without looking like a cave. Like you, I don't need a totally black cave because I have a Black Diamond ALR screen.

I am now looking at carpet. From your pictures, the carpet may be gray or beige.
Is it a shade of gray and is it darker or lighter than your walls? I'm close to replacing the carpet. My current carpet is a golden brown that is way lighter than my walls.

Thanks jrlnc, it is a shade of grey, pretty close to the color of the walls maybe slightly lighter in person. We got it locally, but it is a Shaw Floors product, the style # is E9187, and color code is 0500. It's a middle of the road carpet, but we went for the highest grade padding and it came out very well.

Ok Gents got the Nikon out, it is pretty crazy the difference a camera can make. On each of these sets the first image is the Nikon the second image is my iPhone. Taken back to back, the Nikon pics were actually taken behind the second row, and the iPhone pics behind the first row in an attempt to keep the perspective as close to the same as possible.

She's just not as attractive without Glow'y Spots, Stripes, and the Long Ears. And since I really, REALLY like tall women..............

And besides...whadd'a ya do if you bring her home late from a Date and "Her" Foster Dad gets mad?


On to the imagery.

It's obvious that the multi-spot Metering on the Nikon does a much better, more accurate job capturing the different light levels across the screen surface.

To give the Cell Phone a bit of a Crutch, pics should be take from the Rear of the room, and the image zoomed in to match the size the Nikon is taking. You'd see at least a bit of improvement as far as the centralized hot spotting goes....and less detail getting crushed.

4K Avatar? Nope...not yet. But the 3D print has exceptional quality, thanks to Cameron not scrimping on his Custom made Cameras.

If you haven't seen the Extended version of Avatar....your missing out. Just the right amount of story line drama added to flesh out some weaker / incomplete scenes.

A DES Pulsar Eye Candy experience.....

Just back from a long weekend up in Indy where I paid a visit to FamMann81 to view his Theater and help plan out a Rear Riser. This is an exercise in ergonomics, because of two very tight corners and a minimum of available "Platform" floor space....because the Riser must start out about 18" inside and between the two opposing Walls.





After the brain stormin', and while sharin' a Brew...we watched a bit of France vs Croatia.


All but one taken in some pretty ferocious Ambient Lighting (mostly reflected and not directed)






The next shot clearly shows how bright the directional Spots are set at.............







Here is a Verrrrrrrly interesting and telling shot. Most 1.4 gain screens are going to have a decidedly sharp drop in brightness once 40 degrees Off-Center is reached. Below is fully 60 degrees OC, and I had to put my back against the wall to take it. No Seats there so.......














Some very happy Frenchies !!!!









And lastly, the required Dark Room image.







Time was limited...(...as well as the Beer supply...) so that's all the pics I took but I'm certain more from FamMann81 will be forthcoming.


BTW...while I was there FamMann81 and I managed to get full cooperation from the Wife toward painting the Ceiling several shades darker of the existing Wall color. What a Gal!

Looks pretty amazing. What's the current throw ratio with this set up?

With the Pulsar, a ratio of 1.8:1 minimal is strongly recommended.....although some have gone down as low as 1.6:1. Screen height as relates to viewing (eye) height as much to do with it as well.


Higher Lumen output PJs with lessor light uniformity specs might require 2:1


Lens placement at the top of the screen or slightly lower.

It definitely looks more punchy in the straighter images than it does when viewed farther off-center. I'm guessing this is from the fairly sharp drop in gain/brightness you mentioned, but it certainly doesn't look unwatchable. I'm guessing the gain at screen-center is around 0.3 from that crazy angle, but having a flat-grey or flat-white object near the middle (to see how much brighter or dimmer the screen is compared to something that doesn't lose gain off-axis) could help a lot for showing roughly how little the screen is dimming when viewed off-center.

It would be one of those silly but helpful moments where one less fortunate person shields their eyes from the projector while holding a napkin or something to the screen's center and another person takes a picture from one of the far left/right seats in the front row. Goofy-looking, but a nice point of reference. :P
From there I'd expect a lot less dimming even though the viewer/picture is still somewhat off-axis.

I have a feeling that new riser will fill up with eager moviegoers fast once everything is finished.

Thanks for the info. How about this installation here? Was this 1.8:1?

It would be one of those silly but helpful moments ....................

Silly for sure, as the only example to use would be competing ALR material...if one even wanted to bother. But the shot taken was as far to the side as possible...the other images show how narrow the alcove is.....and the angle shown is eminently watchable outside the confines of the seating area behind. A guess of just 0.3 gain at center would be / is terribly conservative, and not at all indicative of the shown image.



Is it even hard at all to be able to determine that the Pulsar is doing an excellent job in the amount of light shown...even at the degree of side viewing angle where any real loss of brightness would greatly impact visual quality under such lighting? I don't really think so.


Obviously there is some loss...but a 1/2 gain loss would amount to reducing gain to .07, and in that lighting that would be pretty detrimental. DES Pulsar does have a restricted viewing cone compared to a Matte White or Gray, but it's certainly neither ungovernable nor unwatchable, and better at delivering the goods than most any other ALR screen that boasts such gain.

I think that Sony can hit roughly 1000lm+ on EcoLamp. The 16:9 match on that screen is around 51"x91" (about 32square-feet)...over 31ftL at 1.0gain. That would mean even when the screen drops to 0.3gain, you'd still be getting over 9ftL from a dark-colored surface.
Not a bad place to be at all thanks to the screen and the PJ.

Boschpants,

I'm at work right now, but wanted to get back to you while I saw this. I'll get exact measurements for you tomm. The PJ is mounted about 192 in. back and the screen is 120 in. across the bottom. So I'm closer to 1.6. If we're going by diagonal it's 130 in., so maybe less than optimal I suppose. But i'm in love with it! Again I'll get some measurements tomm.

Sorry it took so long to respond, I honestly forgot to check until last night.

My measurement is interesting to me because I don’t know what it indicates about what I should be seeing. As MM has pointed out the preferred throw ratio is farther than where I’m able to mount my projector, but I could not be happier with the results I’m getting.

From the screen to the lens the distance is 167 inches. I guessed at 192 the other day because I knew that 16ft from the screen was a bulkhead preventing me from mounting the pj any farther back. Here’s a pic for reference, the other measurements were for planning the riser build.

So what do you gents think? Could my image be even better than it is for me now? That’s pretty hard for me to imagine. I’m sure there are already plenty of explanations on the benefit of proper throw distance and mounting location on the forums that I can read up on. But I’m always interested in different opinions or explanations as it relates to my situation.

From pictures it looked like there may be some hotspotting going on but I know cameras are pretty much always unfaithful to projectors and what is actually seen in person. I think your layout as it is makes the most sense from a practical standpoint, it's just that some of these ALR screens if you want "ultimate fidelity" it requires some specific placement. If you and your family love the image and can't tell a difference, don't even change what you have.

Love the space you've built!

One thing that works in your favor is that the Screen is mounted up high enough to allow the reflected angle of the image to meet the viewers eyes at a level that avoids dimming.



As far as hot spotting goes....the Camera tendency to accentuate that effect is what is making it seem at least somewhat obvious. It's under the most extreme cases, one can see such happen in the very occasional bright TV image, it's seems virtually non-existent when watching Film. In this instance there is no opportunity to move the PJ so as to actually show what improvement could be effected, and even though the set-up (PJ Throw) is shorter than ideal, the height placement is spot-on, and that is the among the most important consideration, especially when the distance is a bit compromised. Through all that though, the image remains amazing and the image quality as it currently stands make that effort redundant anyway.


I personally look forward to a return trip, where I will earn my Theater squatting rights by helping build the needed Riser behind the Front Row. Truthfully though...the height the screen is placed at "almost" makes the Riser unnecessary. Almost.
