This is an interesting discussion. I often wonder if I should go to the trouble of printing large, and mounting a photo to hang on my wall.
My problem is, I'm not too impressed with small, or average-sized photos that one usually sees on peoples' walls, such as anything from 5"x 7" to 16"x20".
I'm not too keen on the idea that photo prints on the wall have to be approached up close to be fully appreciated.
When I was on an organised tourist trip to Europe and Russia a few years ago, visiting the usual magnificent historical palaces and churches filled with permanent masterpieces which were not just hanging on the wall but sometimes a permanent feature of the wall, it occurred to me that maybe I should print my best photos to the maximum size to fit a particular wall space, and paste them directly onto the wall as a permanent feature.
Of course, one needs a big printer to do this, and my printer is only a modest size. It prints a maximum of only 600mm wide, but fortunately as long as I want, up to 30 metres. (Epson 7600)
If I want a really big print, say 1.8 metres x 3.6 metres to fill a sizable wall, I'd have to separate the final interpolated image into 6 different prints each 600mm wide x 1.8 metres high, then paste them next to each other, onto the wall.
The problem I have is how to manage the joins in the best manner. Should I butt up each print as close as possible to disguise the joins, hoping that no-one notices them from a distance; or should I accept that the join is not going to be invisible, and make a feature of the join?
One way of making the join a feature, that has recently occurred to me, is to photograph the largest window in my house, and use the image of the window frame as a join between the various sections of the total print in order to create the illusion of looking at the photographic scene depicted, through a window in one's house.
If I could patent an idea, I'd patent that.
The scene portrayed in the photograph might be a stitched image of a view of the Himalayas at dawn, for example. I have such an image. Wouldn't it be an enduring experience to feel the illusion that your suburban house in the city precincts actually has a view of the Himalayas, through one of the windows?
Now I would appreciate it if anyone reading this could advise me of the best technique to glue large prints to an ordinary, painted, plasterboard wall, without incurring bubbles and other problems.
