Increasing Resolution

[Tool]

How do I increase the resolution of a picture (so that it's higher quality) while keeping it at the size it's all ready at? Like, what I want is a picture that's 8x10 to have a higher resolution.

That isn't realy possible. As pixels are enlarged they lose quality rapidly.
If you aren't talking about that, I don't see what you mean by Resolution, You can't realy enhance a pictures quality by changing the resolution. You can enhance the colors but ive never come across anything to do with resolution.

yep its not really possible. you can increase the pixels per inch on the image but each pixel still has the same information in it as before so it just makes more pixels with the the same info. the colors are less pixelated when you zoom into the picture but it does not enhance the quality of the image. if your taking the photos your self , then its best to use a camera with at least 4 mp the higher the mp in theory the more information you have in the image. dont be fooled by cameras that cost like 300 dollars and say they have 8 mp on them. they may have that but it really does nothing for you being that you are usually stuck with the same lens. ok i need to shut up. im going way to in depth with a question that was pretty much already answered.
