How many of you make your site's design completely in Photoshop before even beginning to code?
Until recently, I thought the only reason anyone would make their design in Photoshop first and code it second is because their designs were based almost entirely on slices.
However, I've come across people that draw the site in Photoshop, even if it isn't heavily based on graphics. At first I thought, "hmm, what a weird habit and a waste of time." Recently, however, I noticed that a prominent design company that I'm working side-by-side with does the same thing.
This leads me to wonder if I'm the one going against the grain here, because I've always focused on coding from the start, and using Photoshop along the way to make graphics when needed. In my mind, this is more efficient (less time-consuming) and allows for greater creativity (at least for me).
So part B of my question (the one all the way above) is this: For those of you who do draw out the entire design in Photoshop, why do you do it? What are the benefits? Why do you choose to do that as opposed to coding it from the ground up? And how common is this practice in the industry?
