I don't know how many times I here this. People believe there is one right way to produce a solution to a problem. I can't believe that our field is moving so far away from art making. There are always better ways than others, but I think you are really hurting yourself if you believe there is only one right answer.
People believe there is only one program that is worth using. I here all the time how PhotoShop is what you need to produce web graphics. I know Fireworks, PaintShop pro, Gimp, Corel, and other programs can be used to create just as good graphics. I have seen people creating very slick graphics with free programs that came with their computer.
Same goes with techniques to produce the graphics. There are so many ways you can produce the same image it is mind boggling. I have seen people create the same image in completely different ways that it was quite incredible.
So why do we feel this way? In art making it is the personal decision that gets us to the solution. That is how we build our style. I find it almost disturbing that we are losing our creativity to get a nice packaged answer to our problems. I think tutorials are great in the beginning, but are they starting to make the design field lose its experimentation?
I also think the same is true with programming. I have seen programmers that create incredible results that they were told were impossible. It was the creativity of the programmer that truly created a work of art.
So why do we except the answer that it isn't possible? Why do we stop thinking outside the box for answers? I always learn such great new techniques from everyone here that I never tried. There are so many answers to the problem. I don't think you shouldn't take advice, but you should take it as that. I think we are taking advice and making it gospel.
