This section focuses on the effect of Noise in filters in Photoshop.

Practice with a number of pictures
Dust&Scratches captures different pixels in the image or selection and adjusts them into the surrounding image: Radius: Controls how far the different pixels are captured. Threshold: Used to determine how much difference a pixel has reached before it is eliminated.
Despeckle detects areas with large color changes around the edges of an image and eliminates clutter by blurring parts other than the edges without loss of image detail.
The filter mixes the added Noise with the image. Adjust parameters: Quantity: Controls the percentage of added noise. Average distribution: Use distribution to produce variegations. Gaussian distribution: According to the Gaussian bell curve distribution, the resulting variegated effect is more obvious. Monochromatic: If this is checked, the added noise will only affect the hue of the image, and will not change the color of the image.
Median reduces noise by mixing the brightness of pixels Adjustment parameters: Radius: This filter replaces the brightness value of the radius pixel with the average brightness value of the pixel within the specified radius.
This article mainly describes the use of photoshop, the introduction and use of the built-in filter color, need to strengthen practice in order to learn better. Plugins can also be installed to add additional filters. The future will be more wonderful thank you for watching and wish you a happy study
study hard and make progress every day.
