I'm sorry. All ya all can hate me for sayin' so, but if the preceding images are of the Carl's ALR, it does not look to give a very dynamic or bright, high contrast image...even in the dark.
Is it better than a Matte White in ambient? It certainly should be....but it doesn't seem to be all that impressive. Even with the ambient overhead light greatly reduced the washout is pretty dulling.
While it may be a viable and affordable option for those who do not / cannot / will not consider painting, or springing for a really effective yet affordable ALR Screen like the DEA, I cannot agree with any assessment that it is a preferred option.
One thing, Gabre....
You don't mention as to if what we are seeing is the Cal's ALR or the Flexi-Gray you also sampled.
If it is Flexi-Gray...well that would explain a lot. But if it's Carl's ALR, the darker room shots don't come close to looking as good as the ones posted HERE
.....however the difference...at least some, could be attributed to the different PJs being used (Sony 45es vs Epson 5020)
And if the benefit of the doubt is to be given due to Camera woes, then do you best to borrow a better one, because for many on here, any real "proofs" are dependent upon accurate photos. No sense in having your pet project fail to show as good as you know it does. That can make Stinkers like me say mean things in error.
