Good question Jules… I am using Lightroom with a Cintiq 22″ (Shameless Wacom plug :D) and I just went and tried to see what difference pressure would make, and I cannot tell a difference. I tried it with different settings and the easiest way to tell was having zero feather and 100 flow and density to see if I could get a smaller less opaque line and I couldn’t see any changes. So I will check with the Wacom guys and see if that is correct, next time I get together with them.

Thanks for this great tip.

I am interesting to know how the flow and density parameters work when using a pen with a tablet having pressure sensitivity.

Thanks
Jules

David… I know it is a bad habit when I am typing I keep having to go back and fix it… but I missed some… I teach a workshop with a friend and we talk about “affect” a lot… and it is hard to get the fingers to not type out of habit. I also can never type the word “about” correctly, but fortunately spell check gets that one… I need to program the computer to ask me which word I want each time I type affect. thanks for the reminder… the spirit is willing… the brain is soft! 😀

A wonderful lesson, but this comment is not intended for display. It may be only me, but your incorrect use of a word is a bit cringing. You are consistently using the noun “affect” when you mean “effect.” The noun affect means “emotional appearance.” The noun effect means result. The verb affect means influence. The verb effect means to create a result.

Thanks Rob, David Carr is a great guy… I keep trying to encourage him by telling him that I can replace him with a rhythm machine. 😀

The reality is that the Adjustment brush is really just like using a layer mask in Photoshop. We don’t have to create a mask and paint with white or black to reveal or conceal… Lightroom does that for us behind the scenes, so all we see is the brush and its effects, but it is doing the same thing. We become really good at Photoshop when we can learn more about how to work with masks to get them to give us the precision we need… it would then seem that the same thing would apply in Lightroom… so I agree wholeheartedly with your comment here. Thanks

Density and flow are immediate parameters of the brush stroke, and can’t be adjusted real time afterwards they have been painted… unlike the effects sliders that can change real-time. The only way to change the look of the stroke is to use the eraser to lighten or remove that part of the stroke.

Let me try to make an illustration. You have a window and you want to paint is black to block the light… you have control over how much paint you have on the brush and how much you apply to the glass. There may be areas that have less paint and let a little bit more light come through… but once the paint has been applied, you will either have to scrape off some of the paint (with the eraser brush) or crank up the light to let more through, but you can’t change the overall light blocking characteristic of the paint, only how thick the paint is on the window. The adjustment brush is just simply telling Lightroom where and how much of the effect to apply… the adjustability after the fact is solely in the amount of the effect applied such as exposure. Boy, I hope that makes sense.

Thanks Arne!
