Why Do People Buy Photo Art?
There are many reason why people buy photography as art:
Some buy as an investment. Skilled investors know what to buy. They know when to buy and when to sell. If they are successful, they'll make a lot of money.
Some buy because they can afford it. Some specialize in collections of one artist, like the photographs of Mike Disfarmer. Some may prefer to buy signature works of well-known photographers. They buy because they love the work. In the end, it may be a legacy handed down to their heirs, or donated to a museum.
Some would like to start a collection, but it's not in the budget. To those I would say, choose a lesser-known photographer whose work you like. Save up and buy one or two pieces. Consider a limited edition. It may cost a little more, but it might prove wise in the long-run.
Consider starting with a canvas print. You might even have fun "painting" over it with Liquitex transparent gesso or or Clear Tar Gel. This is ideal for painting on colored surfaces and adds a realistic texture to the work. It's fun, and you would certainly enjoy seeing this piece on your wall. If this appeals to you, let me know and I can set you up with an easel, free-standing or table-top, and with a set of six brushes.
Whatever you decide, have fun doing it, and let the art of photography touch you in a personal and meaningful way.
