Today we focused more on Photoshop. We learned about pixels. Pixel is one bit of information in a picture. A picture is made up of thousands of pixels. Each pixel has a different hexadecimal code. When you change the code you will change the bit of information in the picture.

When you print a picture one of the good numbers of pixels is 1800 by 1600. For uploading pictures to internet then the good number of pixels would be 72. If you have more pixels then there will be more details in the picture. It will be best if you reduce he amount of pixels before uploading the picture to the internet. If you do that then that would make the file size smaller so it will be faster and cheaper.

When you decrease the amount of pixels the computer throws away the bits that are not needed. After that if you zoom the picture it will be blurry because the computer already threw out the bits.

Another thing that we learned today is how to crop pictures. Crop pictures means that you take what you need from the picture and throw away what you don't need.
