DPI stands for Dots Per-Inch and we learned that the internet can only hold 72 DPI or else your just wasting space. The DPI for the web is automatically set for 72 DPI because if its over 72, it will automatically be changed to 72 because there are too many pixels and it wastes space on the web page. When we print pictures, we will set the DPI for the picture at 300, im not too sure why its specifically 300, but it adds more pixels and makes the picture look a whole lot better. We print at 300 DPI because the printer can handle it at 300.
This week we learned a few new tools in photoshop. My favorite tools that we learned how to use are the: The Lasso Tool, The Quick Selection Tool, and The Magic Wand Tool. The Lasso Tool allows us to select parts of an image, but its used for free-hand selection. The Quick Selection Tool is used to select certain areas but that area has like (common) pixels (color wise). The Magic Wand Tool lets you do the Same thing but you just click instead of click and drag.
