Resolution

As I read through the article on resolution, I realized that I did not know much about pixels. I knew that they made up images on computers. I knew how to edit pictures by changing the pixel colors and that if I made the picture too big it would become blurry. Besides that i didn't know much.
From the article I learned the most about dpi. I had seen the term before but never really payed much attention because I had no clue what they were talking about. After reading I learned that dpi is pixels per inch. I also learned that its main purpose is for printing and that it, when it comes to cameras, it changes to what you want it to be.
The other thing i learned is about resampling compared to scaling. I knew that scaling kept the same grid of pixels and that it changed for printing only. I did not know that resampling changed the pixel size itself. Another thing I learned that I did not know is that the aspect ratio for a 35mm camera is different that a normal camera
