To become a good designer in any field takes practice, skill and patience; however, a picture designer must also be capable of work under extreme deadlines and within a well-defined budget, as most of the work they do is done on a project-to-project basis. The designer should be able to gather feedback from a number of sources and turn it in to a unique finished product.
In graphic design, the designer must be able to use whatever materials that are prepared for them and remain within the budget given. This requires a person who can listen well, includes a flair for color, a good eye for pleasing design with an understanding of what the client wants. In a nutshell, graphic design is not one job, it is 20.
Graphic designers normally have a four-year degree, usually in art, product design or art background are familiar with most computer graphics software packages, such as Adobe Photoshop, InDesign and Illustrator, etc. A great mixture of coursework usually involves drawing, computer art and design.
It should also include any sort of specific knowledge, like anatomy for medical designers, which directly pertains to a specific area. It's not at all a field for the inexperienced, as of the 25,000 those who try to enter the field annually, only about 60% last the very first two years and about 30% stay in the field at five years.
There is also the chance of many lean years. A graphic designer may decide they may be tired of a lifestyle where these are more like salesmen than artists; constantly the need to pursue new clients for work. Or they may choose to become magazine layout editors or as in-house design consultants.
There could be some, though most certainly not many that make it in the market on talent alone. However, most might need some sort of a certificate or degree to land work in graphic designs. Many employers won't even bother to check out you if you don't have the piece of paper that shows you have been trained and seasoned by some sort of graphic design related program. Receiving a degree or certificate doesn't reflect your talent, but it does show that you have a good firm base of knowledge and that you take the industry seriously.
So, you earn the decision to suck up, get past the lean years and work hard to become a graphic artist; eager to use the cutting edge software packages to create some great new designs. It is just a great career choice and when you specialize in technology or advertising, after that your chances of becoming a good graphic artist increases. There is no better field to buy that will allow you to use your technical skills and creativity to its fullest extent.
