Ready to write a series of tutorials, whose aim is to explore some not commonly used but can we get a lot of windfall function. To start a discussion for a number of Adobe's Fans to try to find some Adobe software is not worth looking at features that make them work for us to play a greater role.
Today we Laijiang Jiang background eraser tool, this tool has not generally Zan did not tell him.
Closer to home, the book received earlier, so why not do this tool? It ye can not do such a? We all know people who did the design, sometimes with pictures, do some small comp to do for the customer to confirm, and sometimes deduction plan deducted half a day in return comp was shot in the news, there will be more heart felt extremely depressed, in fact, The comp is mainly to see a large effect, does not need to do is fine, so the background eraser to come in handy.
Do not lip service, we take a look at the background eraser tool inserted in the end what can be done!
Let's look at the status of tool options bar, the next chart is the default state of the software background eraser tool bar.
What action do not, just draw a map, you can see the results obtained are not ideal, there are some parts of the hand had erased.
Press Ctrl + Z to return the previous step, the tool bar with 30% tolerance, then again, drawing a map, you can see the effect of bad results. So, here's usefulness with Mobanggongju tolerance tolerance is the same as the background eraser tool is the color of tolerance to do the job.
Once again, the screen when the background eraser tool to use, the result is not satisfactory.
Press Ctrl + Z to return the previous step, again using the background eraser tool screen, the result is true. That our analysis as to why the parameters of the two has not changed, there are different changes? Take note of the background eraser cursor, cursor middle of a "+" coordinates, when the "+" cursor position you want to erase the time, better results can be clashes.
Another way to say "+" character cursor position is the sampling point, when the sampling points to determine position, after sampling the color, the color tolerance of similar color will be erased. (If your cursor is not the case, the implementation of Ctrl + K, in the Preferences dialog box, in the "display cursor" in the tab in the Settings)
Speaking of the cursor would start to talk about the background to the three sampling the eraser. There are three sampling methods, continuous, time, background palette. These three methods all have their own very unusual role. Here we are introduced one by one.
Row: "+" character cursor center constantly mobile, will also continue to change the sampling point, then erase the effects of more continuous.
Time: "+" character by pressing the mouse cursor center-click on the color sample, then do not release the mouse button, the sample can be easy to erase the color, do not worry, "+" character Centre will run a picture of the other somewhere. As long as the other color samples to release the mouse button and then press the mouse you can repeat the above operation.
Background Color: "+" cursor at this time has no effect, and this time the background eraser tool only on the background color and the color of tolerance similar to erase.
Select erase a restricted mode. "Discontinuous" erase any location in the sample under the brush color; "continuous" sample of the color and erase contain interconnected regions; "Find edges" erase the color of the link contains the sample area, while the shape of the edge to better retention sharpening level. In fact, these three constraints is not obvious, it is recommended to use "discrete" option.
The last option on the very important, sometimes erasing the background, leaving the edge of a more severe mottle, as shown below:
If you use the background eraser tool again and then trying to remove those miscellaneous side, it is easy to want to erase the image to be erased, particularly the use of "continuous" and "a" sample, it is easy to wipe clean to want to the image, the image will not be erased with a suction tool to set the foreground color, so check the "Protection of foreground" option, it will not wipe to clean the place was not.
