Hi everyone~~~
Today we had computers and we learned some good stuff about the photoshop. A picture is made up of lots of pixels(dots). When you need a picture for printing the number of pixels should be 300 but when you need a picture for webpage the number of pixels should be 72. If you wanted to resize a picture go to tools then resize the click on resize. Resolution is where you put the number of the pixels(eg. 72 DPI). DPI means dots princh. If a picture has a resolution of 300 DPI, the webpage or the picture will download sowly, it takes lots of time. There are lots of formats that you can save your picture as it. One of the best formats is jpg. JPG compresses the picture, it means that takes information and duplicates (loses some information). TIF is another kind of format. It saves every information of your picture(loses nothing). If you save for printing, you should save it in a large format but if save is for webpage, then you should save it in a small format. BMP is another kind of format that loses nothing. If you want to change the brightness of the picture then go to Enhance, then brightness/contrast, then click brightness/contrast. You can also go to Enhance,then brightness/contrast then click level, now you can change your picture in any way you want the color to be. Also we learned how to crop pictures in photoshop.
