Today we are going to talk about the background eraser tool, this tool can be a wonderful, generally we do not tell him.
To get to the end, the book before the text, why this tool is not? How can it be so wonderful? People we've done design know that sometimes when you're working on a picture, to do some small manuscript for customers to confirm, sometimes buckle picture buckle for a long time, but in exchange for the manuscript was shot news, not to mention how depressed, in fact, these proofs are mainly to see a large effect, do not need to do very fine, so the background eraser is great .
Don't just say no, let's see what the background rubber-plug tool can do!
First look at the situation in the Tools Options bar, the following figure is the software's default state of the Background Eraser toolbar.
Do not do anything, on the picture together, you can see that the results are not ideal, the part of the hand has been erased.
Press Ctrl+z to return to the previous step, the tool bar to change the tolerance to 30%, again on the drawing together, you can see the results are good. This shows that the tolerance used here is the same as the tolerance of the magic wand tool, and the background eraser tool works by color tolerances.
Once again in the screen using the Background eraser tool, the results are not ideal.
Press Ctrl+z to return to the previous step, again in the screen using the Background eraser tool, the result is good. So let's analyze this, two times why the parameters have not changed, but there are different changes? Note that the background eraser cursor, the middle of the cursor has a "+" coordinates, when the "+" cursor position in the position to erase, you can wipe out the better effect.
To put it another way is to say that the "+" word cursor is the location of the sampling, when the sampling location to determine the color of the sample, the color tolerance of similar color will be erased. (If your cursor is not the case, perform ctrl+k, in the Preferences dialog box, set in the "Show and Cursor" tab) Category:
