Where is fuzziness in photoshop

The whole computer locks up? If so, do you have to toggle the power to reboot the whole machine? Sorry for the lack of detail! It's Photoshop that locks up, not the whole computer.

I just tested by opening up an AI file in PS, and it's working okay. The Color Range tool becomes unresponsive, and is forever present in the foreground, no matter what application I switch focus to. The only way to fix is to force quit PS. I don't get this with PS , just I thought the update today might fix it, but it didn't. Hence, reporting it here. I'm a little surprised you're having an issue because we did fix an issue I upgraded to Big Sur a couple of days ago, and it's still happening there, too.

Just wanted to give you some more info! View other replies. When Photoshop locks up and color wheel is spinning, get a spindump and process sample.

I recreated the issue again, and then tried to do a screen recording to show you, but I couldn't recreate it while the screen recording was happening. Go figure. When the lockup happens, I don't get a spinning color wheel, just a regular cursor. I can move the color range selection window around, but that's all I can do in Photoshop at that point When I try to paste system info here, it won't let me post the reply.

Perhaps it's over the 30, character limit? Just had the issue again, but it didn't happen until I tried to hit "cancel" on the color range selection tool. No beach ball, no program crash, just the color range selection tool stuck on the screen and it won't respond to any input from the mouse except I can move the color range tool window around the screen. When I force quit, the force quit window does not display "not responding" for Photoshop Found under the Select menu, Color Range opens a pop-up window containing a couple of dropdown menus, eyedroppers and checkboxes, as well as a preview of the selected area in the image.

When opening the Color Range selection tool, photographers are shown a selection opportunity that uses eyedropper tools. Click on a color in the image and Photoshop will add that color—and similar pixels based on the Fuzziness indicated on the slider at the top of the window—to the selection. Switch to the additive eyedropper and additional clicks will add to the selection.

Choose the eyedropper with the minus sign next to it and the color range can be edited by removing clicked colors. Adjusting the Fuzziness slider increases or decreases the sensitivity of the sampling. We use the Fuzziness value the same way we use Tolerance. The higher we set the Fuzziness value, the more brightness levels we include in the acceptable range.

A Fuzziness value of 40, for example, will select all pixels that are the exact same color as the pixel we clicked on, plus all pixels that are within 40 brightness values lighter or darker. Any pixels that are 41 or more brightness levels lighter or darker will be excluded from the selection. The Tolerance option, though, is very much a "hit or miss" type of thing.

If we click on the image with the Magic Wand and realize we didn't get the selection we needed because we used the wrong Tolerance value, all we can do is enter a different value, then click on the image and try again. This "trial and error" approach to selecting pixels can get frustrating very quickly.

This is where the Color Range command really shines over the Magic Wand. Unlike the Tolerance value which forces us to guess at the correct value before we click on the image, the Fuzziness value can easily be adjusted after we've clicked! All we need to do is click once on the image to make the initial selection, and then we can adjust the selection simply by dragging the Fuzziness slider left or right to increase or decrease the range.

A live preview of our selection will appear in the preview window as we drag the slider so there's no guesswork needed at all. We'll see an example of how Fuzziness works in a moment:. Now that we've covered the basics of the Color Range dialog box, let's see it in action. Here's a document I have open in Photoshop made up of a simple dark-to-light blue gradient, with a yellow bar running through the middle:. Let's say I want to select part of the blue gradient using the Color Range command.

First, I'll go up to the Select menu at the top of the screen and choose Color Range. Then, when the Color Range dialog box appears, I'll make sure my main Eyedropper Tool is selected which, as we learned, should already be selected by default :. With the main Eyedropper Tool active, I'll click somewhere in the middle of the gradient to sample a shade of blue:. If we look at the selection preview window in the dialog box, we see that I've now selected part of the image based on the shade of blue I clicked on.

The white area represents the pixels that are selected, while the black areas are not part of the selection:. If I click on a different part of the gradient, I'll get a different result. I'll click on a darker shade of blue this time:. Notice that no matter where I clicked on the blue gradient, Photoshop completely ignored the yellow bar in the middle.

If I click on the yellow bar:. The preview now shows me that the yellow bar is selected, while the blue gradient above and below it is being ignored:. I'm going to click again in the middle of the blue gradient so we can take a closer look at the Fuzziness option and how it lets us adjust our selection on the fly:. When I clicked on the middle of the gradient, my Fuzziness value was set to 40, which means Photoshop selected the exact shade of blue I clicked on, plus 40 shades lighter or darker.

But what if my Fuzziness value wasn't high enough and I needed to select a greater range of colors? Not a problem! All I need to do is drag the Fuzziness slider towards the right to increase the range.

As I drag the slider, the preview window updates to show me my new selection. I'll increase my Fuzziness value to , which means I'm now selecting all pixels that are within brightness levels lighter or darker than the shade of blue I initially clicked on. I can see in the preview window that I've now selected a much larger section of the gradient.

Likewise, I could have dragged the slider towards the left to lower the Fuzziness value, in which case less of the gradient would be selected:. Notice that the display in the preview window isn't limited to just pure white and pure black. Instead, it transitions smoothly and gradually from white to gray to black. That's because the Color Range command is capable of partially selecting pixels.

Any pixels that are not the exact color we clicked on but still fall within the acceptable brightness range set by the Fuzziness value will be partially selected. These are the gray areas in the preview window. The closer an area is to the color we clicked on, the more selected it will be, represented by lighter shades of gray.

Darker shades of gray represent areas that are further away from the color we clicked on and are less selected. This ability to "partially select" pixels can sound a little strange, but it's why the Color Range command gives us much smoother, more natural selections than what we could ever get from the Magic Wand.

Or, to put it another way, for a given setting of the fuzziness slider e. Perhaps I should have add that my interest is in making selections of BW photographs to use for making layer masks for certain effects.
