How to enlarge digital photography without losing image quality?

This is a technique introduced by Scott Kelby in the book "Professional Processing Technology of Digital Photos", and he describes a technique used by Jim Divitale, a master of digital photography. It is said that this technology can enlarge the digital camera image to the whole poster size, and the degradation of image quality is almost invisible to the naked eye. Right? Let's try it together.

1. Start Photoshop and open a picture.

2. Select the "Image Size" command and set it as shown in the figure below. Pay attention to two places: first, check "reset pixels" and set the interpolation method to "quadratic cube"; Second, set the unit of document size as a percentage and only use the percentage of 1 10, which will increase the image of 10%. Believe it or not, when the image is enlarged 10%, for some reason, it doesn't seem to blur and soften the image. It's strange and interesting.

It takes many times to enlarge the image to the size of a poster, so it is best to define the above operation process as an action. Every time an action is performed, the image increases by 10%. This action should be performed about 10 to 15 times.
