While there’s no harm in mentioning the particular design software you use, or whatever your tools of the trade may be, focusing on it isn’t going to bring you any business.
If you’re running a website for potential clients to find, you obviously want your design portfolio, project enquiry or design quote pages, and other contact information to be readily available to visitors. This is the information clients are looking for, and the information that will get you a job.
As for what tools your using? They probably don’t know or really care for that matter. They’re looking for someone who can provide a service, not someone who has purchased a piece of software.
I recently visited a fellow logo designers blog and portfolio where, at a glance, the site seemed more about the Adobe Creative Suite than anything else. There was a prominent post on having “purchased” the software, a permanent visual element on the site stating Now using Adobe CS5! with a collection of program icons, each project description from their graphic design portfolio was signed off with Created using Adobe CS5 and was accompanied by the same icons.
What advantage is there in displaying your new tools for the world to see? There isn’t one really…
Any of the above logo designs can be created in Illustrator CS, CS2, 3, 4 or 5. New software may bring new tools and may make the process more efficient, but the end result will be identical. The knowledge held, information interpreted and the creativity used when wielding these tools however, will drastically affect the outcome.
Anyone can wield a hammer, not everyone can build a house.
Graphic design is no different. Clients won’t pay you thousands of dollars just because you’ve purchased a piece of software, if that was all that was needed they could buy it themselves. Sell your skills and ideas, not your software.
