Eraser deletes part of the imageusing freehand brush stroke.
Just click and drag the cursor over the image.
As I'm erasing, the area becomes transparent.
If a layer's protected from transparency, you can see this little padlock, the eraser will use background colorto cover the deleted areas.
The same rule applies to flat images: documents with only background layer, and the original background layer that is partially protectedwith the padlock on the right.
You can see that mybackground color is showing through.
The Eraser tool can be used in threedifferent modes displayed in the option bar.
Choose "Brush" mode to have brush optionsincluding airbrush capability.
That will give you much softer edges as you erase.
Choose "Pencil" for pencil optionsand to erase with hard edges.
And finally "Block" mode that hasfixed size, shape and texture.
As you can see, all other optionsare grayed out in the option bar.
Let's undo the changes using History palette.
As you can see, History palette contentdepends on the active document.
Background Eraser is usually employedto isolate part of the image.
It allows you to use freehand brush stroke to delete specific colors.
Conceptually, Background Eraser isvery similar to Color Replacement tool and they both have the same brush sets, modes, limits and tolerance.
"Continuous Sampling" mode samples the color to delete as youdrag your cursor over the image and it's best used when more than one colorneeds to be erased to isolate your image.
However, working in that mode can be tricky so it is imperative to understand the process.
When you click on the artwork, Background Erasersamples the color under the crosshair right in the middle of the brush cursor.
As you drag your mouse, Background Eraserwill continue sampling the color to delete at crosshair point using the rest of the brush to erase.
So even when brush edgesgo over the neighboring colors, they will remain unchanged as long as the crosshair pointdoesn't touch the areas you want to preserve.
"Sampling Once" mode samples the colorto delete when you first click on the area any it only erases initially sampled color.
It's best used when there is onlyone color you want to erase.
Click and drag the cursor to sample and delete:make sure you don't release the mouse! To resample the color, release the mouse and repeat the process.
"Background Swatch" mode will only deletethe color that is set as a background.
Pick Eyedropper tool from the toolbox, hold Option key[ALT key in Windows] and click to sample to setthe color as your background.
Then go back to the Background Eraser tool, make sure it's in the correct mode and simply click and dragto erase the background color.
Adjust your tolerance to increasethe color range if necessary.
Limits are responsible for the way colors are erased.
In "Contiguous" setting, the Background Eraserwill only delete connected areas under the brush.
Just like so.
"Find Edges" sets the same limitsdeleting only connected areas under the brush but this option is not as sensitive andbest works with color contrast.
"Discontiguous" setting deletesall the areas with sampled color even if they are not connected.
And finally "Protect Foreground Color" option.
It does just that:it protects your foreground color.
Make sure your foreground coloris set in the toolbox, go back to Eraser, make sure option is checked, and then click and drag to erase.
As you can see, your foreground color is safe.
Magic Eraser tool is one of my favorite.
It does a wonderful job deleting unwanted colors.
Just like Magic Wand, it recognizeshues, saturation and lightness, and logically, has Magic Wand options like tolerance anti-alias and contiguous.
To use, simply clickon the color you want to erase.
Unchecked "Contiguous" if you wantto delete the color through the entire layer.
Let's see it again.
"Contiguous" checked and unchecked.
Gradient and Paint Bucket toolscan be classified as fills.
Paint Bucket fills the areaswith foreground color or pattern but as opposed to the Fill in the Edit menu,that fills the entire layer or selection, Paint Bucket only fills the color you click on.
To use the tool,adjust the settings in the option bar.
Set "Contiguous" if you only wantto fill the connected areas and click on the color you want to fill.
In my case, I want to fill transparent areas.
You can also uncheckthe "Contiguous" option to fill all the same color areasthroughout the entire layer.
Generally, I don't like having background coloron the same layer with my image.
It makes it much harder to change, especially if it's a pattern or gradient.
So whenever I clean my artwork,I create a new layer for the background.
Now I can apply any background I wantlike pattern, for example, without affecting my clean image.
And for any further changes I will use Edit menu Fill command.
Now, the Gradient toolis more like Edit > Fill command.
It applies gradient to the entire layeror selection, regardless of the image colors.
Gradient tool is used to createcolor blends at various angles.
A simple way to fill an image with gradient.
Choose foreground and background colorsin the toolbox to set the color range.
Then place the cursor where you wantthe gradient to begin, click and drag to determinewhere you want it to end, and release the mouse to apply the gradient.
You can choose the gradientto appear linear, radial, angled, reflected, and diamond.
As I've already mentioned,similar to the Edit > Fill command, the Gradient tool appliesblend to the entire layer or can be limited with a selection.
In addition to a foregroundand background colors blend, you can create your owngradient presets that will be listed under the sample icon in the option bar.
Click on the sample icon tobring up the Gradient Editor window.
You can click to select fromvarious presets as a starting point.
To change a color, double clickon the gradient stop symbol and choose a new color from the color picker.
To add a color,click in the area between color stops, then double click to set a new color.
You can also change gradient transition placementby sliding the color midpoint.
To duplicate a color,hold Option [ALT] key on the keyboard then click and drag the color stop.
To delete the color,click on the color stop to select and click "Delete".
Use the top of the slider to set transparency.
When you are happy with the gradient,type the name, click "New" to add to the presets and click "OK".
Now you have your new gradient listed in the presets.
