I've been thinking about digital cameras and how they take such small images. Most of the newest, more expensive "good" digital cameras still only have a resolution range of 15 - 17 megapixels. But then there are the large format cameras, capable of 100 megapixels. The digital versions are far too expensive, most cost that of a new car. But the traditional large format camera, that seems like the answer to this riddle since it is a reasonable price. Taking a photograph with a large format camera, having that film developed, then scanning that film into the computer, that appears to be the answer for me to get vast photographs to work with and make the gigantic imagery I want to create.. in the future at least. I intend to set up scenes with models and props to help sketch out the composition in the real world before fleshing it out in the digital realm.
I look forward to pursuing this old technology with the new technology to push my art to the next level in the coming decade. I'm sure it will help emphasize the theatricality of the imagery I intend to create. But most of all, the biggest objective in the art is to turn it from a small window into my imagination, into a larger wall sized space, a portal that the viewer will be able to seemingly fall through.
There is a great article on low cost large format cameras and related equipment here.
