The above mentioned pictures, have been PS, in addition to some pictures clearly full face acne, but the grinding skin is very smooth; there is no name, living forged a. ...

First, the tool to see through the law

View pictures EXIF raw information. If it's a photo taken by DC, then you can also retain EXIF information to determine whether the picture has been edited, in Windows 7 system, the mouse right click on the picture, in the pop-up menu click "Properties", if there is no such information, the picture is completely passive hands and feet, may be PS over, It may have been cropped. Of course, this method is not absolutely reliable, even if the picture information is complete, does not mean that the picture has never been PS, after all this information also has a way to save after editing.

Click "File" to load the picture, the software will automatically analyze the picture and give a report. At the bottom of the report, if there is a Assessment:class 11 image is processed/edited, this indicates that the picture has been PS. The results of the Jpegsnoop test were four: The photos were processed, the photos were probably processed, the photos were very likely to be authentic, and it was impossible to tell if the photos had been processed.

It should be noted that the tool to detect the identification results of a certain deviation, some carefully PS pictures can not be recognized, such as fat sister to PS into a pretty girl, will sister PS to Hong Kong Central and so on. There may be misleading, for example, the author simply deals with the brightness and saturation of the picture. At this time, we need to rely on experience to judge.

Third, the experience judgment method

Human PS. Nowadays, the major forums, Weibo popular "oval" (many are using the "liquefaction" tool PS, the role of the tool is to modify the contour of the object, such as the human face into the push will form a oval), but we Asians where there are so many oval, big eyes girl? It's possible that their photos were all PS. We can find flaws in the hair, chin and surrounding background. For example, the oval in the upper-right corner of the picture, her chin too sharp, beyond the normal range, the hair on the right has been distorted by liquefaction tools, judging from the beauty's overall hairstyle, it should be long straight hair, rather than wave hair.

The face is finished, let's talk about figure. The quality of the body can also be used liquefaction tools PS, so we do not envy the network of "oval", "small long legs", because such photos, most of them PS.

People add or subtract PS. In addition to the human body PS, the character or increment PS also need to rely on experience to judge-mainly through splicing traces, space perspective, color, lighting effects and light direction to judge.
