Photoshop: Distort Filters
These are used for more extreme physical changes to an image.
Diffuse Glow
Use this excellent filter for adding a soft ethereal glow to highlights, as well as textural grain if required. Effects can vary from just a touch in the highlights to giving the whole image a bright ghostly appearance with just diffused shadows appearing.
Pinch
Use this filter to squeeze or inflate images. Apply a percentage for different effects.
Twirl
This works in a similar way to pinch. Use to rotate the image (or a selection) around a central point in the frame.
Noise Filters
Use the Add Noise filter to add a grain like pattern. This is useful when applied subtly to remove the purity and sharpness of digital images, or to give the impression a grain. Tick the monochromatic option to avoid any unwanted specks of color noise being seen. The Texture filters menu also has a Grain filter that has several interesting styles of grain and interference. However, it does not have monochrome option, making the grain look too colorful, though it is very effective for images converted to Grayscale, which can later be turned back to RGB.
