Yeah pretty much what everyone else said. You could start by scanning in really rough drawings so that you have to do more drawing on the tablet. For example if you were drawing a person, scan in an almost stick figure type drawing so that all you have is the proportions and rough shape before starting. It’s quite a good way to get used to sketching on a tablet because it makes it a little less daunting but you’re still drawing almost from scratch.
I second *mousbomb's zoom out suggestion. I typically try and work at about 25% zoom in PS, and move in to about 50% for details after the overall peice reads. I do still struggle with this and want to detail the heck out of things.
You want your lines to look good at print size. It doesn't matter what they look like at 100%.
I have also heard good things about putting paper over your tablet, but have not tried, as I have become accustomed to the slick surface at this point. While I am not satisfied with where I am at artistically, I am pretty happy with the progress that I have made in the last year or so.
Just keep plugging away, and you'll get used to it. I was seriously frustrated when trying to draw on the tablet originally, but now it is SOOO much faster that I haven't drawn on paper in about a year.
Although I would probably benefit from starting pieces on paper, I normally start all my work digitally. Perhaps you have tried these already, but a couple things I have found that helped me when starting a sketch digitally: Change the opacity of my brush to 30% or even lower. That way I can go over line work several times and the intended path usually becomes the darkest. Zoom out. This helps me get general forms with very few brush strokes. Don't use control+Z a whole lot. I have a bad habit of overusing it. But I've found that if I always rely on it, progress on my piece slows tremendously. Sometimes those accidental strokes become a source of inspiration and direction for your piece.
Anyway, if you are already comfortable sketching on paper, I don't think it would take you too long to become comfortable with sketching on a tablet.
I am a complete newbie I am not an artist traditionally nor digital. I have never sketch anything whether on paper or digitally. I don't like tracing the image I want to be able to sketch digitally from scratch on a blank canvas. I found using guide on the reference photo then copy and paste the guide on a new white layer helped me a lot just finished practicing a new sketch please see link
I am not saying my sketch is good but i've managed to draw a sketch just practice you'll get there. I use wacom intuos 4 pen and tablet. I've tried with mouse it was utterly useless now I use my wacom pen all the time.
Practice. And accept that digital art isn't nowhere similar to traditional. My way of digital sketching looks entirely different from pencil. Yet, I manage to make useful sketches. It's a matter of acceptance.
1. Unplug your mouse. Put it in a drawer. Forget you have it. Cover up your touchpad if you're on a laptop. 2. Use your computer as normal. Whenever you'd reach for the mouse, use the tablet instead. Maybe play some games that involve precise control of the cursor now and then. 3. If you want to play a game that expects you to push the cursor against the edge of the screen to move, you can plug in the mouse. Put it away when you're done - it's now a specialized game controller in your world, not a general input device. 4. Profit!
