Determine who you are going to present your portfolio. Usually show creative development need among potential customers, so by promoting your services. The other important factor for the designer is the recognition of his talent and success among colleagues in the "design shop" - you'll want to assert yourself.
If we are talking about potential customers of design services, the portfolio should contain precisely those works that best tell about you as the artist. Include projects that are already embodied in the material or in the Internet.
Show the process of creating each project in stages. Describe the goals that you had set by the client. A potential customer will be interested to see your working process and the end result of their goal task. Specify which projects were accepted by the client and which are not (if you include them in the portfolio), and also what were executed for participation in the tender or contest.
Collect only the best specimens. Let them be little (no more than ten), but they have to be diverse. Show the whole range of your skills, from sketching logos to website design.
When forming a portfolio of the strongest work place at the beginning and at the end, because human perception is arranged in such a way that the greatest imprint in it leave the first and last impressions – use this effect.
To impress the fellow designers, the presentation of your creations must have a slightly different concept: here you can give room for a flight of bold design ideas. Make your portfolio special, and Express your personality.
Methods here can be varied, from drawings in the author's technique, non-standard format or form to use unexpected materials and media. Also in the portfolio of purely creative nature quite naturally can look like your original poetry, prose or interesting aphorisms. All this work, fringed with your own illustrations or collages, can distinguish you from the crowd and bring well-deserved recognition among colleagues and lovers.
When choosing the presentation format of their work, focus on your profile. If you are working with printing, paper – printed portfolio would be the most logical choice. If you are a web designer, your projects are best represented online. To send samples of work along with a summary it is best to choose PDF or PowerPoint, and a personal interview take the printed version.
In any case, your portfolio should have a simple and clear structure (by creation date, by customer, by category). Let the works speak for themselves – when they are looking at should have further questions.
