Sabs - I am sure the Misty Evening base is a FLAT WHITE wall paint. I used a FLAT WHITE ceiling paint because there is more white base pigment in ceiling paint but I doubt that it makes any difference. My gallon of True Value ME clone paint had 24 units of B (lamp black) and 4 units of D (thalo green) pigments.
JimmyDaves - I assume that the SMART III calibration standards are NTSC which means they will give you the same results as the AVIA disk that I have. The standards are identical - the difference is only in the presentation on the disk. The key is to calibrate every time you make a change in your environment, e.g. paint on the wall, filters, location of the projector, etc. My drywall was simply a wall that was installed new three years ago when I remodeled and was in great shape with only a few nail holes and a chair rail attached. If you don't have a large, smooth wall there are many other materials available to hang and paint - just read this entire thread! I removed my chair rail, filled the small holes with spackle compound, sanded the spackle, put a base coat of masonry/stucco paint down followed by two coats of the light grey paint and then recalibrated the HS10. BTW, I don't think the masonry paint is required. It was simply what CMRA, the first guy with ME paint, had around.
I leave the filter on at all times for convenience and use the re-calibrated Cinema setting for DVD's and the re-calibrated Dynamic or Standard settings for HDTV. The results are astounding. And I wouldn't recommend you base any decisions on photographs you see on any forum. The camera and picture environment as well as your computer viewing settings make for a ton of variation in those pics. Make your decisions on what your eyes see on your wall! You may want to try just painting 1/2 the wall with light grey over the flat white base coat and try it with various calibration settings - particularly the hi/lo lamp, black and brightness settings.
Have fun! We watched Toy Story 2 last night and the 3 and 5 year old's mouths never closed. They just stared in awe and with mouths agape (of course they had seen it many times before on VHS)! There was a definite 3D effect, particularly in the scenes with shiny floors and reflections.
BTW, we like the grey paint so much I am painting the entire cellar room with it, including my bright white suspended ceiling panels. It reduces the reflective ambient light and makes my wife much happier than the alternative I had in mind - flat black!
