I really have two questions. One is about how digital cameras actually capture images and create image files. The other is about how cameras end up taking rectangular pictures. I mean, if you look at cameras. the lenses are circular, so how do they end up taking rectangular pictures, and why? Why are movies and photos always square, rather than circular?

I now have a Canon, but it’s all beat up and is getting a bit slow. What are the good brands for digital cameras?

I have currently the HP photo printing software which is good in its drag and drop feature. Just Drag the selected picture to the template and it adjust the size. But it is a “budget unfriendly”. I throw a lot excess paper because its template cannot be edited.

If your high school or work place offered photo printing services, how much would you be willing to pay for one picture for each of the following sizes:
- 4×6
- 5×7
- 11×14

I want a good program to photoshop anime (for example:changing colors of the picture) Which program would be the best? Some one told me that Adobe Photoshop works, is that true? If so which one should i purchase? What other photoshop programs work? I kinda want it a little cheap too but i guess it could be kinda expensive as well.
