Non Reflective Glazing?
I was looking at some frames today and
noticed the reflections from the glazing.
Are any using the non reflective?
Any source suggestions? Dan
Masterpice Anti-Reflection Coated Glass
If you’re in the US and have a Michael’s arts & craft store in your area look at their display of “Masterpiece” anti-reflection coated glass. It’s a shadow box with a butterfly inside. There are three vertical strips of different types of glass on the shadow box. The outer strips are: plain glass and textured anti-glare glass. The center strip seems to be missing until you look closer. It’s the coated Masterpiece glass and is very effective at eliminating reflections.
It’s pricy though. A 22” x 28” sheet that I had cut for a 16” x 20” print was $108. For some things it’s worth it. The coatings form slicks easily when cleaning just like the coatings on a camera lens or MC filter and, of course, can be damaged much easier than plain glass.
The photos I framed in Masterpiece glass look a great deal like no glass was used. Regular glass holds back quite a bit more light. If I’d thought of it I could have metered through both coated and uncoated glass and given you the difference in f-stops. I didn’t and so I don’t have the numbers, but, the difference is significant.
Michael’s frequently has framing specials that include the Masterpiece glass for a bargain price.
Regular glass has glare and a green tint. Regular acrylic has glare but no green tint. Textured glass and acrylic will reduce glare but there is a loss of sharpness that gets worse with distance between the glazing and the image. Some textured glass and acrylic is very poor and looks bad at any distance. I am familiar with Cyro textured non-glare acrylic and it is a very good quality with a very minor loss of sharpness that is difficult to detect without an A/B comparison test. The next level is glass or acrylic with anti-reflective coating. The coating is typically very sensitive on glass and requires special care until assembled into the frame. It is also very expensive. Glass with the anti-reflective coating such as TruVue Musuem glass will also have a reduced iron content which reduces the green tint.
Another option for glass or acrylic is UV filter. For glass it is a coating, for acrylic it is built into the acrylic. In both cases the UV filter causes a yellowing or warming effect of the glass or acrylic.
The most economical way to handle reflections is with proper lighting. The lighting should be on the ceiling close to the wall so that you only see the reflection of the lighting is you are well below the image looking up.
TrueVue Museum glass is the best I have seen for anti-glare and light transmission -- really remarkable and quite a leap ahead of other glasses used in framing. As already noted, it is expensive.
Surly not the glass from Picture Frames Destination!

I've been shopping that site and find the custom frames
and glass to fit reasonably priced. I am looking though
for non-glare glass. Did I overlooked an option? Dan

The glass we use at Frame Destination is a quality framing grade glass so it has less green tint than some other glass but I am afraid it is not tint free. Although we sell non-glare acylic we do not currently sell non-glare glass. We may eventually carry non-glare and uv-filter glass but we could never carry Musuem glass since the coating side is so sensitive.

High gloss images such as Ilfochromes are usually framed with UV-retardant glass such as that made by Tru-Vue (one of the most expensive glass makers on the planet), which does also make non-reflective glass. Be aware that non-reflective glass can make an image, particularly peal or FB prints, look very dull and flat, even under directional lighting (gallery spots). Reflections will not be a problem when frames are hung at the correct viewing height and illuminated to set them off.
“The photographer must determine how he wants the finished print to look before he exposes the negative.
Before releasing the shutter, he must seek 'the flame of recognition,' a sense that the picture would reveal
the greater mystery of things...more clearly than the eyes see." ~Edward Weston, 1922.
That non-glare glass is not the same as the coated Anti-Reflective glass (Museum Glass, or AR Glass, or Masterpiece). The non-glare glass gives a kind of frosted, low contrast look.
