Stiching Photos

I would definitely take a look at David Hockney's stitching work. I have a poster of Pearblossom Highway in my apartment, and it's awesome. Here it is:

A word on the resolution. If you stitch images together, you have more pixels but the same resolution. Resolution refers to the number of pixels in a given surface area. Say you have an image that's 10x10 pixels. That's 100 square pixels. If you stitch four of those images together, that's 400 square pixels, but in a 20x20 pixel canvas, which makes the resolution identical. Even if you were to overlap them, such that the final image was, say, 20 pixels wide by 10 pixels tall, that's 200 square pixels but still the same resolution. Stitching iamges together only increases the image's total number of square pixels, not the number of pixels in a given surface area.

That makes sense. My follow up question though is does a 10 MP camera have the same resolution of a 6 mp? I know a 10 has more overall pixels but it also has bigger dimensions right? Is there a standard resolution that all cameras shoot at. for example 100 pixels per square inch.

I don't have a lot of experience with digital cameras, but I can tell you with absolute certainty that megapixel is a term for resolution, not canvas size. A 10mp camera has higher resolution than a 6mp. That's why they're more expensive. It's not that the image size per se is larger, it's that the image is better quality.
