Sijun Forums :: View topic - Drawing on Wacom tablet with Photoshop, Curved lines not so

adev · Posted: Sat Feb 02, 2002 10:26 pm

So I picked up a Wacom Graphire2 4x5 tablet the other day. I installed the Painter Classic just to experiment in it, but when comparing Photoshop 6 to Painter I discovered something interesting.

If you look at this picture, it's obvious. Everytime I draw in Photoshop, all my lines look like that. They're never smooth curves like in Painter. Is there a way to fix this?

try tweaking the brush spacing and stuff, othe then that I have no clue. It could just be somthing thats going to just be that way, because of the progam, but good luck none the less.

I've noticed the same thing. It could just be the two programs use totally different algorithms to compute?

i'm pretty sure everyone gets that (it had been brought up a few times in the past) .. so it's a photoshop issue

That's just the way Photoshop is. Regardless of the tool used (mouse, tablet, light glove, 3d tracer, etc.), the line Photoshop draws is very obviously segmented into straight peices. Painter on the other hand does a lot in the background every stroke you lay down to make sure it makes a smooth line with no segmentation, no matter how fast you move your pointer. There is no way to fix this in Photoshop.

Its cause by your tablet only sending data to the computer at about 50Hz. Most newer mice can do at least 100.

That doesn't make sense.. since both of those examples used the SAME computer, SAME tablet, and done within 1 minute of each other.

Painter has a brush option, under the spacing tab called "damping". Adjusting this makes painter straighten out any small jiggles in the brush strokes. Setting damping high takes a sharp corner and makes it smooth. Of course, one can get carried away with it, but it's a nice feature.

PS brushes are not ideal for lineart or sketches. Stick to painter, cuz that's what it's best at.

Adev: but Painter and PS have different methods of interpreting the data they're sent by the tablet. Painter's method is more computationally expensive, but results in smoother lines.

Incidentally, Corel Photo-Paint will let you control how much interpolation you want it to do on your strokes . . . zero is about like Photoshop, while full on isn't quite as nice as Painter, but adequate for most things.
