Brush tool paint an "8"

[gabrielh]

Hello all,

When using the Brush tool in Photoshop, adjusting its opacity to (say) 50% en then painting the number "8"---so by crossing the curve with itself---how come the crossing does not add its opacity? If you would draw with a real brush on a real canvas, and come back to the same point in one single stroke, then that would be darker and darker. Why does Photoshop has another rule for this, should that help for a certain application? I find it rather not realistic, so I was wondering...

Thanks for any input, comment about the subject!

Unlike a real brush it won't add opacity on itself during a continuous draw like a #8.
Try an X when you have to lift the pen and you'll see a darker area where the lines meet.

Indeed, I noticed a darker area when two different strokes meet. But I don't find it natural that Photoshop doesn't add density in one line stroke... Is there any reason this would be more useful? Any parameter in some Preference Tab that could change that, any discussion about this topic?
Thanks for any comment, I appreciate!

I think it has to be like that.
If you want 50% opacity, you get 50% opacity.
Just my opinion, but I think it would be difficult to use any other way.

Ok, thanks for your comment! If you see it that way, then, indeed, it should be that way.
But can you change the opacity with a pen pressure and a pen tablet? I searched quite a bit, but couldn't find anything, so help would be appreciated! If this would be possible, then it doesn't seem not logical that the center part of an "8" would be darker. But perhaps changing the opacity with pen pressure is not possible?
Thanks for all comments!

I'm not sure if the less expensive tablets support it but opacity and the thickness are both controlled by pen pressure on my intuos4.
Here's more info on the pen.

Ok, thanks for your comment! I use Wacom Bamboo fun, and I can control the thickness with pen pressure using the Brush Tools in Photoshop, but didn't find any way to change the opacity. Do you have to manually set some preference in Photoshop? As my pen tablet supports pen pressure, I hope this can be done!
Thanks for the help on this!

you can change the opacity with pen and pen tablet.

Check your settings.

Thanks a Steve, that was JUST what I was looking for---never saw that little icon! It works like a charm! Great! Thanks!
