For the Photoshop project, we had to understand that image size would lower the internet server. Therefore, knowing that the number of a picture is a key to speed up the website. Usually, a picture of 256 colors, Which means that this size will keep the picture with maximum information, at the same time would be saved as the smaller file size. For the last picture, I used Photoshop to add a filter to the original photo. By playing with filter, you could add many styles as you like.
