I will share a couple of thoughts...
However, I am still pretty much confused. I inquired and there are no premium less-reflective glass available in my city for framing. They say as no demand, there is no supply.
Okay, at least they know what it is. When you see it, you will observe that there is virtually no reflectance, but it will show some coloration such as you might expect to see on the face of a multicoated camera lens. It's great if you can afford it. Rich.
IIRC, due to textured nature, matte reflect less light and image looks bit dull..
Yes, in fact is is not non-reflective glass at all. Printing "matte" has a similar effect. It just reflects equally in all directions. The result is that dull, washed out, flare-like look of which you speak. It may look fine on a soft, airy, high-key image like a baby's portrait, but not so good where colors need to be rich, lines need to be crisp, and blacks need to be black.
On the other hand, printing matte or on textured paper, or putting the image behind the cheap so called non-glare glass can serve to mask minor shortfalls in image sharpness or excessive grain or noise.
So, I need some special enhancement in photo before printing matte??
When printing matte, perhaps you should be thinking of that soft effect as being
the special enhancement.
Maybe our friends here can add some other thoughts.
