Either way, do you have a recommended paint mix for my scenario? I looked at silver but its not good for ambient light.
You can be assured you will have a 122" screen that will perform well under pretty high ambient light conditions. If fact, a Silver Fire v2.5 4.0
even more so, but that degree of dark Silver/Gray especially demands the optimization of the PJ Throw / Screen size scenario. And as the darkness of any SF mix goes deeper, the Gain does as well. Silver Fire v2.5 4.0
is approx 1.0
There are no magic bullets in all of this. A Mfg Screen that size that would do what we propose to do with paint cost $3,500+ . There's that.
You buy....install, and start watching. But watching can be difficult while also wiping tears from your eyes over the drop in your Bank account. There is "definitely" that!
Paint that can do all the above requires a nearly perfect application. Fortunately, the inexpensive Electric HVLP Guns available are not a severe hindrance, cost wise. But they do cost...and they "are" required. So there is all that.
Spraying inside does require some inexpensive masking with Plastic...and of course a Respirator Mask. But the actual art of spraying with the type paint and the type Gun comes easily.
Easy alternative to the above DIY Screen.? If you use the Panny, at the suggested throw, you could simply use a moderate Flat Gray "rolled" directly on the wall, which is already "Primed White" and sanded, then you can get what many find entirely acceptable results.
Personally speaking, my involvement with DIY has never been based on "acceptable results". But that's me. And everyone should have an alternative.....if one is available.
In your case, without the Lumens and Focal length considerations outlined, even the advanced DIY applications would fail to be "Exemplary" performers in high ambient light. So...to even remotely consider a "Basic & easy" DIY application, you have to accept your restrictions as far as equipment and positioning.
Don't shoot me....I'm just the messenger. At least you do have viable options you can consider. Sadly, many do not, and even more tragically, they often don't find out or realize such until they have spent time and money.
See how fortunate you are?
BTW, I will try to get you a link for some really effective, roll down "Sliding Track"style Blinds made especially for deeply recessed Skylights like yours. If the Skylight closest to the left of the screen was covered just 50% down, the difference in how much actual sunlight could strike the Screen Wall would be reduced tremendously, and that would be quite an improvement and assist in your having a really quality image, even at 12:00 Noon on a sunny day. Then again, if such Blinds were in place, then if "You" wanted to view something at such a time, and there was no "getting by quite nicely" involved, but rather for "Dark Room" excellence, just the employ of such Blinds would allow such to happen. I'm not talking about total darkness...not even greatly subdued lighting. It's all about the difference in ambient light Foot Candles present, and how they stack up against directed lumen output on a given surface. Sunbeams are the bane of "any" display. As are "directed" Incandescent, Florescent. or Halogen lights. Judicious lighting design / room color selection is usually all it takes to allow people to use less severe criteria as far as selecting equipment. When such cannot be accommodated, well.....there's solutions such has been offered to you to consider.
