I wonder if the subject matter affects your decision? I would opt for matte because sometimes the glare off a gloss finish can make it difficult to view.

My thought is to go with matte or lustre for the same reason you mentioned. Gloss might be a mistake.

Is it clarity that's affected with the matte? I think that happens with the non-glare glass types. I'd probably go with a matte finish also, though; maybe lustre, but not sure how much sheen there is to the lustre.

Have you talked with a sales specialist about the pros and cons, as well as glass types?

This is a photographed print that I'm ordering online, and I've never done this before, so I'm not sure of the best finish. Here's the artwork. I've emailed the artist to see what he recommends, but I've not heard back yet.

When you get it framed, you also should consider getting conservation glass. I am told it protects the artwork from fading better than regular glass. Ask about it at the framer's--they should have samples so you can see the difference. The one I saw did have a slight "tint" to it, but since I was also framing a large photograph, I wanted to do what I could to keep it beautiful as long as possible.

I like just plain matte finishes on photos. For Skypathway's reasoning.

That's good to know about the conservation glass. I will be sure to ask the framer about it.

Btw, here is what the website says about the different finishes:

"Which is better, Glossy, Matte or Lustre® finishes?
It is a personal choice and sometimes can depend on what is being printed.

The Glossy option is perfect for detailed/technical prints or photograph images. However, please note that glossy prints cannot be framed due to the fact that the print sticks to the glass.

The Matte finish offers a flat, texturized finish with little to no glare. Some find this finish is better for paintings and darker prints although it works for any type of image.

The Lustre® is wonderful for both, capturing the best qualities from Glossy and Matte and combining them into one beautiful finish. Please note, the Lustre finish has more saturated inks which can sometimes result in a darker image."

Hmmm, with a such a luminescent landscape, I'm thinking I wouldn't want the material it's on interfering with the image. But you never know! Asking the artist is a very good idea.
