PS Image high quality pixel amplification technique

Introduce a picture amplification technique. This technique is said to be able to increase the digital camera image to the entire poster size, but with the naked eye can hardly see the quality of the image. Is that so? We might as well try it together.

1, start Photoshop, and then open a picture.

2, select the "Image size" command, according to the following figure set. Note Two places: one is to check the "Reset Pixel", and the interpolation method set to "two cubic", the second is to set the size of the document unit as a percentage, and only to use the percentage of 110, which will increase the image 10%. Believe it or not, when you increase the image in increments of 10%, it does not seem to blur and soften the image for some reason. It's strange and interesting.

3, to the image to increase the size of the poster needs many times, 3lian material, so it is best to define the operation process as an action. Each time you perform an action, the image increases by 10%. You might want to do this 10 to 15 times.

4, the enlarged image. Let's look at the quality of the picture.
