Bitmap vs Vector

Bitmap Vs Vector

Bitmap

A bitmap image is a range of different pixels, to build up an image. They are essentially known as rastered images and use a multiply of selected colours to become a image. The outcome of these photos are very good in quality. They look smooth as the pixels are small and together they use a gradient of the same patterned colours with the help of anti-initialise.

While using Photoshop you must be very careful on resizing the image because it will eventually lose focus and quality to how it originally was. 

Take for example this image of the rose, you can definitely see that the computer has tried its best to arrange colours to build it back up. The way how this picture is zoomed means that the image was considerably smaller. once making a bitmap image is to change the resolutions on either the image you are using or the page you are going to create it on. 

Vector

A vector image uses a series of different polygons to ensure that the image stays the same and doesn't lose quality. All the areas a circle for example will be very smooth based on a mathematical equation in the computer application that deals with vector; in this case it's Adobe Illustrator. Vectors are used in a lot of graphic design like for example t-shirt designs posters to get the message as clear as possible. 

Today I made a vector image of the yin and yang logo and then I created my own version. Using the technique that Oli taught the class; the negative space idea of tricking the mind of what is or is whats not.
