Explaining graphic design for the non-designer
If you do any kind of marketing you will end up working with images and graphic designs – be they of your own creation or from an expert designer. And as a marketer one of the skills you need is to ‘translate' between non-marketers and non-designers and those who help create the visual elements of a marketing campaign. This is one of the best explanations I've seen for graphic design for the non-designer. Whatever you needed to know or terms you've heard tossed around but were maybe afraid to ask what they really meant or the difference among them.
Those using images on the web or in printed materials [which is honestly, everyone!] pay special attention to the chart about 2/3 of the way down on the left about where to use different types of raster images. And don't worry, it explains what a ‘raster image' is. [hint: think the type you take with your digital camera, JPGs, or those funny GIFs]
