Thanks for the feedback Joe. While we don't go fishing for compliments we do appreciate those that come our way.

All water-based paints go on looking milky (which is why you can't judge the true color of a paint in the can or before it dries) and turn transparent as they dry (I mean the binder or vehicle and not the pigment). I don't think you will notice much of a change after a day or two.
OK, thanks Don - I will fire up the PJ again tomorrow to get a good feel for how it will look going forward. I am going to try to get a couple photos up on my build thread tomorrow as well.

Re: Cream&Sugar™ Ultra

Hello.

I've been reading through the various threads of various generations of various paints. I do have one question that I was unable to answer...

Currently, I have a mix of Black Widow and a mix of C&S Ultra. Is it possible to mix these two current formulas together to make a variant of Scorpion or am I better off just tinting some of the C&S Ultra to find a middle ground between the two grey extremes?

thanks

I don't know if Don has attempted that yet. But I don't see why it wouldn't work. If you mix them you have to send me a sample!

Welcome to HTS!

Yes, you can mix BW™ and C&S™ Ultra in any proportion you please. Both paints are neutral so the resulting blends should also be neutral.

Re: Cream&Sugar™ Ultra

Thanks so much guys. I plan to paint up a few small panels with the three paint mixes to see which I prefer.

For the sake of curiousity... I have an Optoma H77 which will be shooting a 85"ish image from about 14'. The walls are a warm brown beige not too much darker than BW. Most viewing will be done in a dark room, some times with a little ambient light if we need to find the coffee table. Would BW be a bit dark for this setup or am I better off with a lighter tint?

Thanks in advance.

I estimate that BW with your Optoma and 85' screen will be the perfect match, as long as your bulb is in good condition and has not too many hours of operation.

Interestingly enough the answer to this question depends on what signal source you are using to send the video to the PJ; a progressive signal produces a much brighter image than one from DVI or an interlaced source. According to projectorcentral your PJ is kicking out 385 lumens with a 480p source and Normal lamp mode (which is the low lamp mode), but only 240 lumens with a 480i source. This means that you would be hitting an 85" 16:9 screen with ~17.8 foot candles of image brightness using a 480p source and only 11.1 fc with a 480i source. All this assumes a new lamp so you can cut those brightness values by about half as the lamp ages giving ~8.4 fc and ~5.6 fc). All that said, the lower limit of watchable image brightness is very subjective, both Mech and I have no problem watching a BW™ screen being hit with a measured 12 fc, but we have had members here complain of a too-dark image if it was much less than 16 fc.

If you were running on Brite lamp mode BW™ could work fine by itself, but if you want to get longer lamp life then I would go with a lighter mix. Since it sounds like you have fairly dark walls and either no, or very limited, ambient light during viewing I would suggest a mix of 33.3% BW™ and 66.6% C&S™ Ultra (assuming you have both paint mixes). This should give you about an N8.4 level of neutral gray, but give you a brighter image than an OTS paint of the same shade.

Re: Cream&Sugar™ Ultra

Don, i 'm a little confused...is this the pj we are talking about?

http://www.projectorcentral.com/Opto...ulator-pro.htm

Are you refering to calibrated values?

He's referring to whatever it was that PJ Central used Yiannis. It's from page two of their review and it's rather interesting.

Brightness. The projector has two light output settings, Normal and "Brite." Normal is the factory default, and it is in fact referred to as eco-mode in the owner's manual. The "Brite" setting puts out about 1/3 more light, and Optoma anticipates that this will reduce lamp life to 2000 hours.

We noticed a great deal more light output with a progressive scan signal than with interlaced or DVI. This phenomenon is common, but not normally to the magnitude we see it on the H77. The brightest picture was achieved with 480-progressive input in Brite lamp mode. After calibration at this setting we measured lumen output at 510 ANSI lumens. Switching to an interlaced input signal dropped the ANSI lumen reading to 320. In Normal lamp mode, the ANSI lumen reading with 480p was 385, and with 480i it was 240. The optimum operating mode is progressive scan with "Normal" lamp mode, producing 320 ANSI lumens.

Thanks Mech!!

I don't know if back in 2004 ''This phenomenon is common..'', but in 2012 sounds a little bit like wrong settings either from the source or in signal processing.
