Re: Best paint mix for on-wall projection with Epson PowerLite 8350?

With your PJ mounted at 11.5' and going with a 117-118" screen means your lens is wide open and the only adjustment is zooming the lens to get a smaller and brighter image. However, I manually calculated image brightness levels instead of going with the PJC Calc figures and if you use Eco mode and Cinema mode that will drop you down to about 10.5 fL (preferred viewing range is 12 to 16 fL). The PJC Calc seems to be based on using the bright lamp setting and Living Room mode with the 8350. They say colors are very good in this mode. BTW going from full lamp to Eco mode drops brightness 22%.

'Silver Screen' will work well if you use Eco and Living Room modes, but if you choose to use Cinema Mode I would recommend going with 'Snowfield'.

Black Widow™ would give you an image brightness comparable to 'Silver Screen', but produce a darker screen that will absorb more ambient light. Since you won't have any (or minimal) ambient light Black Widow™ really isn't the answer for your HT. If you really want to try a reflectively enhanced mix then think about Scorpion™ or C&S™ Ultra.

This is great. I think painting your screen with an OTS neutral gray paint first will probably work well for you, but it's nice to know that you are willing to repaint if you think the image needs help in one aspect for another.

If you think I don't need an enhanced mix, I won't use one. No problem here.

Regarding the different modes, I'm not really to worried about bulb life. I mean... I don't relish replacing a bulb, but I'm getting a spare along with the projector (and they're not too expensive anyways), so I'd much rather deal with a possible replacement than have too dark of an image.

With respect to Snowfield, who makes that paint? I assume that it's a lighter paint than Snow Screen (since you're recommending it for use with the dimmer modes), right?

'Silver Screen' is a Behr color and 'Snowfield' is a Glidden color. You should be able to have just about any brand of paint tinted to match those colors, the formulae should be in the stores color-matching computer.

Yea, 'Snowfield' is a slightly lighter gray than 'Silver Screen'. Both of these colors (I had them made in Valspar Ultra Premium at Lowe's) are quite neutral in color which means your screen won't change the color of the image being shot on it by the PJ. Having a truly neutral screen makes it easier to calibrate the PJ properly too.

One final question: is there any particular reason to use Valspar Ultra Premium tinted to match Silver Screen? Or are there other paints that would be good to tint to Silver Screen? Does it matter?

I tend to use Valspar Ultra Premium (for both screen mixes and as a general paint around the house) because I have had a fair amount of experience with it and it has always worked well for me. It is relatively inexpensive and available from a chain (Lowe's) that is very prevalent in my area. Lowe's has the most accurate paint-tinting machines I know of (they can add the different color tints in 1/768th ounce increments). That said, just about any brand of paint should be tintable to match Behr 'Silver Screen' including major brands like Sherwin-Williams, Benjamin Moore, Pratt & Lambert etc.

The only name-brand paint I would recommend against is Behr Premium Plus ULTRA, the older Behr Premium Plus (the stuff that ISN'T advertized as paint and primer in one) has worked fine for me.

Great.

I'll give Valspar Ultra Premium and Silver Screen tinting a shot. I'll send the instructions to the contractor today, but it will take a while before I can report back. I'll let you know how it turns out.

Thanks for all the help!

Re: Best paint mix for on-wall projection with Epson PowerLite 8350?

Hello everyone. I am a long time reader but decided to join to get an answer to my predicament.

I did not want to create a new thread on the Epson 8350 as there are already two, I hope I am not thread jacking.

I just purchased an Epson 8350 and would like to create my own screen. I built a new wall for the image to be projected onto, so I would like to paint the screen on the wall.

The projector will be mounted to the ceiling with a 4 inch hang. No ceiling obstructions. It will be mounted 11.5-13.5 feet away from said screen. Looking to do a 100" to 108" 16:9 screen

The walls will be a deep gold color with a white ceiling. Floor is carpet, its two tone gold and burgandy

What gray paint should I use. I am new to this so please let me know if I omitted anything necessary info. Thank you.

Hi LWest, welcome to the forum!

You will find a lot of info in the existing 8350 threads and you could pretty much extrapolate your screen needs from that, but never be hesitant to ask questions.

With your PJ in Living Room mode and full lamp you would be getting between 24 and 19 fL of image brightness with a 108" screen, the difference being due to PJ mounting distance. Going to the smaller 100" wouldn't make a perceptible difference in image brightness. If you want to use Cinema mode and low lamp your brightness will take a hit and be in the 10 fL range. So a lot depends on what modes you use.

If you would have minimal ambient light in the room during viewing you could use the same paints I recommended to ThinkRob, namely Behr 'Silver Screen' (a ~N8.3 neutral gray) or Glidden 'Snowfield' (a ~N8.5 neutral gray). These are paint COLORS and you could use about any paint brand you like. 'Silver Screen' will give you a bit more contrast and richer colors than 'Snowfield', but it will be a ever so slightly dimmer image than you will get with 'Snowfield'.

If you want to use the dimmer modes on your PJ then I would recommend thinking about using our reflectively enhanced mix called Cream&Sugar™ Ultra. This mix is a N9.2 (almost white), but does offer a bit of image contrast enhancement compared to a true white paint; however, it is designed for no ambient light viewing,

Wow! Thanks! That is really helpful. Thank you again. As the OP stated, I am not opposed to having to repaint to get the perfect screen color.

I guess my only question now is, say I would like to view in Living Room mode w/ some ambient light present, should I go with a reflectively enhanced mixture? Or possibly the Black Widow you mentioned above? I'd like to be able to view sports in a low light environment and movies in the dark. How would I be able to make a compromise so that it looks equally good in both lighting enviroinments? Would Silver Screen get me there or is that not even possible?
