There are a lot of ways to apply filter effects in Photoshop, but one of the most common is to use the Filter menu. This menu has a variety of options that can be used to change the appearance of an image. One option that can be used to change the appearance of an image is the Blur filter. This filter can be used to blur objects in an image. The blur effect will make objects look more blurred or indistinct. Another option that can be used to change the appearance of an image is the Gaussian blur filter. This filter can be used to blur objects in an image so they look like they have a Gaussian distribution. This will make objects look more blurred and indistinct than if they were not blurred at all. The last option that can be used to change the appearance of an image is the Curl filter. This filter can be used to curl or round edges of images. Curl filters are great for making images look more polished or professional.
