brush resizing on the fly

For photoshop cs6 on windows it should be Alt+Right click, hold and drag left or right.

Are you dragging the cursor?  Left right for size, and updown for hardness.

I suspect your hardware does not support it then. What do you see in Preferences > Performance?  is GPU acceleration ticked or greyed out?

The good news is that you are going to love the new computer you are going to need to buy.  Your whole Photoshop, and computing in general experience is going to be so much more enjoyable.

It should say Use Graphics Processor in Edit>Preferences>Preformance.

Taking into account this post and your other one about the clone stamp, i'd look at your mouse or keyboard, but i'm leaning toward the mouse and/or mouse driver having problems

This is what you should see when having the Brush Tool selected and pressing the Alt+Right mouse button

(you might also see a box showing the size, hardness and opacity)

Even if Use Graphics Processor is unchecked you would at least see the brush outline (without the red part)

RK I'd trying to think back to CS4 or CS5 when this feature was introduced.  I remember there were a lot of people with driver problems, and only getting part of the outline, and I thought I remembered it being to do with GPU acceleration.  You are the XP expert around here though.  I just hope the BANG is not too destructive when that countdown timer reaches zero.

try this:

open an image.

select the eyedropper tool. ensure that 'show sampling ring' is checked on (show sampling ring is found in the options bar).

click and hold/drag anywhere on your image like you were normally use the eyedropper tool. You should see the color sampling ring.

Now try the alt/right click/drag to re-size the brush. Might work. This is a bug that I think was in CS5, so I'm not sure if this applies to CS6 or not. Try it out, it worked for me.

Just to cover all the basics,, also check the Nvidia website for the latest driver for your graphics card and verify photoshop cs6 is up to date by going to Help>Updates from within photoshop cs6.

are you sure you're in RGB mode? Go to Image/Mode and make sur you're not on indexed color or something

As the others have said above, you should be able to see a red brush size / hardness preview.

You're holding down the Alt key while right-clicking on the image?  You actually have to do that then drag the mouse a little ways to see the brush size or hardness change.

It doesn't work off to the side of the image in the workspace area.  I've requested Adobe change that, but they haven't gotten to that so far.

Maybe you have a grayscale image?  Try Image - Mode - RGB Color.

to paint on a levels layer you need to click on the circle+rectabgle icon, not the split circle icon

Post some screen grabs, please, showing what you're seeing.  Perhaps with a visual cue someone can spot what's wrong.

I suspect that most tech support people have never used Photoshop, and work from a screen that guides them through a question and answer process.  Those tech support people probably have to cover all Adobe products, and there are >30 just in Creative Cloud.  I also wonder if those same Tech Support people also field calls for several different banks, and half the Telecom companies in the world. If, heaven forbid, they get a quiet moment, they cold canvas folk asking if they would participate in a short survey, but they are made to target time zones where people are likely to be at home and finished their evening meal (i.e. relaxing in front of the TV)

Go to the main menu and choose Select/Edit In Quick Mask Mode - if it's ticked on, then tick it off, then try everything over again

you have to post images of what's going on

You need to connect to the forum, and use the camera icon. You cannot attach from email.

But I suspect that your document is very long and therefore the layers icon scale accordingly:

Also, you cannot paint with any color on the MASK of a levels ADJUSTMENT layer, just black and white and greys, and neither paint on the adjustment itself, as it is just a parametric change, and not actual pixels.

those images are too small - you need to upload larger images for us to see... but I did manage to enlarge it and what you're experiencing to me is normal behavior - it doesn't look like there's any problem here.

First - in the layers panel, at the very top right corner, click the small lines with the down arrow and choose Panel Options. Then choose 'none' for thumbnail. Now your mask and adjustment layer icons should look proper.

Next, once you've added the levels adjustment layer, change the levels (brighter or darker) by double-clicking on the split circle .(not the split circle at the bottom of the layers panel but the one beside the 'eye' icon on your layer)

Next, click once on the box/circle (just to the right of the split circle) icon so it's highlighted. Select the paint bucket tool. Choose black as your foreground color. Fill the entire layer with black - now your level adjustments that you made should disappear.

Now, select a brush, choose white as your foreground color, and paint onto your image - what this does is it 'unhides'  the levels adjustments that we just filled with black. So black hides the levels adjustment, and white shows it.

i still don't see any problems - it looks like Photoshop is doing what it's supposed to do

first:

the levels adjutsment layer was added, and  the levels were darkened, so your entire image appears slightly darker. 

Next, you filled that same adjutsment layer with black as your foreground color, so what this did was 'hide' that darkened adjustment layer, so your image returned to normal. The darkened levels is still there on that layer, but it's hidden (by filling the entire layer in black)

now when you change your foreground color to white (just use the color picker to chane your painting color to white), just choose a soft airbursh tool and paint on to the adjutsment layer - now because you're using white, it is "un-hiding", or showing the darkened levels and the gray smear is just the darkened levels showing through- take note of your brush opacity - make sure it's at 100% for starters. If you want that 'gray smear' to appear darker, then double click on the split-circle icon (beside the eye icon on your layer) and the levels window should show up again - then re-adjust those levels sliders again so they're even darker - you'll notice that gray smear on your image darkening as you pull the sliders down.

The degree of darkness that the gray smear appears to be is totally dependant on how far you pull the sliders in the 'levels' panel 

for example, you can pull the sliders all the way in one direction and the gray smear will turn very very dark, or pull the sliders the other way and the gray smear will turn very very bright (all the way up until it's actually white)

what you're showing us looks to be total normal behavior - you might try reading up on adjustment layers to get a better understanding of what's actually happening, but there appears to be no problems with your Photoshop or your camera
