How to set up PS feathering? How to set up PS feathering? Apr 06, 2025 pm 07:36 PM

PS feathering is an image edge blur effect, which is achieved by weighted average of pixels in the edge area. Setting the feather radius can control the degree of blur, and the larger the value, the more blurred it is. Flexible adjustment of the radius can optimize the effect according to images and needs. For example, using a smaller radius to maintain details when processing character photos, and using a larger radius to create a hazy feeling when processing art works. However, it should be noted that too large the radius can easily lose edge details, and too small the effect will not be obvious. The feathering effect is affected by the image resolution and needs to be adjusted according to image understanding and effect grasp.

Only by continuously optimizing these steps can the performance of MySQL database be improved.

To reduce the impact, it is recommended to use a smaller feather radius, copy the layer and then feather, and carefully compare the image quality before and after feathering. In addition, feathering is not suitable for all cases, and sometimes tools such as masks are more suitable for handling image edges.
