Same thing with projectors that are too bright.
FYI - I fully calibrated my projector using Spyder 4 system with a calibration disk.
All colors, gray-scale and alignment were adjusted.
So it is not poor calibration.
With my calibrated projector, in bright scenes, especially transitioning from dark scenes to bright scenes, bright scene detail gets washed out, unless I close down the iris.
Exactly like in real world.
And I can't stress enough the impact that good HT light control and colors, fabrics have.
The absolute worst HTs are the fancy, high end theaters you see in magazines, full of reflective surfaces and light colors that just destroy contrast and thus perceive image brightness.
It is due to these bad HT design practices that most people perceive a need for more output from their projector; i.e. Best Buy plasma like image.
Best HT designs, by contrast are quite drab, with 100% light control, very dark and non-reflective paint and surfaces, and absolutely no movie posters or fancy (reflective) wood work.
These HTs minimize reflections, maximize contrast and perceived brightness. As a result you do not need a light canon or plasma like image.
And FYI, most movie theaters are not 14-16 ftL.
Take your light meter with you next time you go.
You are certainly not wrong for enjoying whatever brightness you find pleasing since brightness is very subjective, but understand that your picture is technically considered dim just going off the numbers and those that prefer something closer to the 16fL baseline are certainly not worthy of the title "Best Buy plasma like image" viewers which is just ridiculous. Understand that going off the information you have given us that you are getting ~4fL image brightness with a new bulb (!!!) which most people would consider VERY dim (especially on a new bulb). If you are happy, that is all that matters, but to come in here telling people who like acceptable brightness (what most consider acceptable at least) or higher that they like blown out "Best Buy" images, especially considering a lot of these folks are calibrated is just absurd.
With low lamp, max zoom (which you are close to being mounted 16' from a 150" diag screen), -15 iris and D65 all of which you claim to be watching at, you are starting out with about 260 lumens going off the cine4home numbers which gives you a 4.25 fL image on a new bulb if you do the math. This is technically VERY dim. Again, if you are happy that is all that matters, but most would find this unacceptable in a 100% light controlled room with a new lamp.
If you are getting washed out bright scenes, you have a calibration issue. Most likely your contrast is simply set to high which can be easily adjusted with a calibration disc if you have not done so (check brightness as well). There is no logical reason you should be getting washed out bright scenes at anywhere close to the SMPTE recommended brightness levels.
All of us in this thread certainly understand the importance of good light control with minimum distractions and all the people responding to you have put forth the effort in their theaters to get this done as well as they can all things considered. My floor, sidewalls, part of my ceiling (the other part is flat black paint), couch, and rear wall are all black velvet which is the darkest material I have tested (even better than protostar which I use some of as well on my first reflection and bass trap metal frames......yes I am that anal) and also the best at killing off light. In my black hole of a room with my calibrated RS45 (ChromaPure, Lumagen Mini, D3 Pro meter), I would find your ~4 fL image (again, this is with a new bulb!) unwatchable and disappointing, not to mention it is about 1/4 of the SMPTE 16fL standard (the general considered acceptable range is 12-20 as I remember) which is obviously just a guideline, but at 4fL you are definitely in the "dim" category.
Again, if you are happy with ~4fL on a new bulb, that is all that matters but to come on here telling people they are Best Buy plasma image lovers if they like something closer to the SMPTE 16fL standard, especially considering this is coming from someone watching with ~4fL brightness on a new bulb is flat out ridiculous. I cant even imagine how dim 3d must be in your setup in all due respect!
Just to keep this in perspective since you keep bringing up plasma, from my reading (someone correct me if I am wrong) calibrators in general shoot for ~30 fL brightness on a calibrated plasma set in a light controlled, dark, lights out HT room and closer to 40 fL calibrated in a more lit up daytime setting. This is obviously a far cry from the general image brightness numbers we are talking about with front projection and again to label those as Plasma Best Buy image is just silly.
Having said that, how many times are you going to rehash this topic? You have brought this up 3 or 4 times now. Edited by Toe - 5/14/13 at 10:05am
