Getting textures with a digital camera.

Hi everyone, I want to start getting my own textures with a digital camera and I wanted to know what camera is good for the job, so please name a few for me. Thank You!

anything 5 mega pixels and up. A flash would be nice too.

It could ba a good idea to have a lens wich flattens out the geometry (telephoto), but I'm not sure if it would work right.

Avoid wideangles lens. Macro can be a good idea to get some details, but if you have a hint of perspective, you'll get strong field of depth effect, wich you don't want when picturing textures.

Use a far distance and zoom, that flattens out geometry.
If you have a constant ligh situation it helps ALOT when cleaning the textures up.
Cutting out the textures and wrapping them into a square is easy, so you do not need a perfect straight angle.

Ofcourse, the better the camera, the better the texture. You can find the horizontal line and vertical line and cut it out with a transform to correct the perspective. Then comes the painful part of normalizing the brightness and contrast. I do not know a magic way to do that... usually you carefully check the histogram for parts of your image and try to get an even brightness. As I said, if you have a propper light when taking the pictures, this step can be even ignored sometimes.

Then offset it by 50% X and Y so you see the seams. Those do not fit and you will get a clearly visible line. Eleminate it with cloning, smudging and whatever your artistic skills allow, then offset the picture back and check if you have any left over artifacts.
