Vector vs Bitmap

Reading the article vector vs bitmap it discusses how they are both images but are shown in different ways. Bitmap's are more for photography based, when we say 300 dpi, or high resolution, we are usually referring to the pixels on the display. If you have a high resolution photograph, it means their is many details that must be included. So it is not a good idea to stretch or compress the photograph because the changes of loosing that clear image quality is very high, and therefore makes it uncomfortable to look at. So in the end a bitmap is good for high quality images, and its downfall is not to resize the image. Compared to the vector which can be resized. A Vectored image uses a mathematical approach instead of pixels, making it easy to stretch or compress without making the image look distorted. The downfall to using the vector images is not being able to use images or icons with a lot of detail. These are important questions as a designer to ask themselves when making any type of design. it is important to consider what types of images they should use. For example, using many high quality photographs for a website might not be the best idea, instead using smaller icon vectored shapes might be better, for people to upload, making the website more functional. However, making a layout design where the designer can use many high quality pixel photographs could be a good idea, with just having one or two vectored shapes. These are important decisions for a designer to make because have to choose between vector and bitmap all the time, and to be able to understand the difference and where to use them appropriately will make us better designers.
