Originally posted by jatrax One thing on metal prints that is not always obvious is that there are several 'finishes'. The bare metal allows the aluminum to show through and in my opinion looks ghastly with color photos. I've never tried it with a black & white though. I generally use the white gloss undercoating which gives the resulting image a very glossy and detailed look. There are also several matte style finishes that reduce the reflections if being displayed where that is an issue.
This was what I was trying to get at earlier. I find that the bare metal can be ok in color but isn't always great in black and white.
I printed a few photos out a while back for my work office. I had some photos I took of the Northern Lights in Iceland that were awesome with the metal shining through. It made the lights look like they were right there glowing. I do think it is gimmicky overall as I remember seeing a gallery full of color metal prints like this and thinking it looked a bit cheesy.
For a black and white I did, I went with the white to preserve the detail and contrast in the image. In all cases, I had bought 4x6 samples of the images (or croppings to test the dpi) to see how all the finishes looked.
What I've determined is that the metal showing through works best when you are dealing with a generally darker (like a night shot) with very high contrast or highlights. The white base works better for daylight images that are brighter where most of the details are at the higher levels and most likely to be lost with the metal showing through.
In all cases, I've liked the glossy better. A matte finish seems to limit the wow factor, and I'd rather just go with a canvas or standard print at that point.
