PS Pull Map Tutorial: Strange to pull the map

The purpose of PS-pull is to separate the target from the background by filtering.

In principle, all of the cutout are: 1, machine identification and artificial identification of the combination of 2, forged

1, artificial recognition: is the human brain to identify the part to be acquired, and then manually sketch it out, such as with a brush, pen tool

Machine Identification: Magic wand Tool, quick selection tool, magnetic lasso tool, etc.,

The disadvantage of machine recognition is that it is difficult to correctly and completely identify all the pixels we want when the difference between the target and background pixel is not obvious.

And the disadvantage of artificial identification is a lot of small parts, completely with manual method extremely slow, (such as using the pen tool slowly buckle hair ...). )

So I found that all the core of the pull-back tutorial is to use manual adjustment to make the machine recognize all the things we want as much as possible.

For example, the commonly used channel-pull map, is to find the target and the background of the most obvious color channel, and then in the color adjustment to find the object and background of the largest difference

Ratio, increase the accuracy of the PS machine recognition, and then manually with the brush tool will not recognize, or identify errors (the most common is the screen edge and background adhesion) where to repair, so that greatly improve the accuracy of the drawing.

2, since it is to pull the map, there must be some places can not perfect separation, for this, the best way to deal with is to forge: With the clone stamp tool, brush drawing board tools and so on

The above content is oneself sentiment, wrong place also to correct

The following is about the specific content of the drawing, I mainly wrote: The passage of the detailed map, small parts and the background of the treatment of adhesion--how to quickly forge a clean perfect edge

The end of the tutorial, the above is the PS to pull out the map tutorial, I hope to help you!
