Is there a general formula for image size vs. print size?
What size images do I need for common print sizes, such as wallet size, 8x10, and 16x20? Is there a general formula?
How could that size change if, for example, a 16x20 was printed on canvas rather than photopaper?

Why is the 50mm prime lens the most standard?
Seems that most photographers choose the 50mm as their prime lens (at least from what I've read). I'm looking at getting a prime lens for my Nikon D3000 and the cost difference between the 35mm 1.8 and the 50mm 1.4 is quite significant. I know…

Why do we use RGB instead of wavelengths to represent colours?
As we know, the colour of a particular beam of light depends on its frequency (or wavelength). Also, isn't that the information which is first captured by digital cameras? Then, why do we use formats like RGB (or CMYK, HSV etc.) to represent colours…
