Filters in Photoshop: Filters are the tools which are used to improve the performance of the image. The filters menu lists more than a dozen different categories of filters.
Some blur or sharpen the picture, some distort it and some turns it into imitation
Types of Filters :
- Artistic filter.
- Blur filter.
- Distort filter.
- Noise filter.
- Sketch filter.
- Texture filter.
- Other filter.
1. Artistic filter:-
Artistic filter apply a certain amount of abstraction to the image. How much depends on the
kind of filter and to an even greater degree, or how we set the filters variables. Most of
Photoshop’s filters have a preview window in which we can see the effects of changing the
setting before we actually apply the filters.
Some of artistic filters are given below:-
- Colored pencil.
- Dry brush.
- Neon glow.
- Sponge creates.
- Under painting.
- Water color.
- Colored Pencil:-
It is used to draw an image on a solid background the edges are retained and given a round crosshatch appearance. The solid background show through smoother areas.
Dry brush :- It paints the edges of image. The filter an simplifies a image by reducing its range of colors to areas of common color.
Neon glow:- Adds various types of glows to the objects in an image and is useful for colorizing an image while softening its look.
Sponge creates:- Images with highly texture areas of contrasting color, appearing to have been printed with a sponge.
Sponge creates:- It paints the image on texture background and then paints the final image over it.
Water color:- It paints the image in a water color style, simplifying details in an image, using a medium brush loaded with water and color.
Blur filter:- Blur filter softens a selection or image. These filters are useful for retouching. They smooth transitions by averaging the pixels next to the hard edges of defined lines and shaded area in an image. The blur filters are:-
- Blur and blur more.
- Motion blurs.
- Smart blur.
Blur and blur more:- These are two basic filters. Blur is very subtle. The blur more filters procedure an effect three or four time stronger they that of the blur filter.
Motion blurs:- It blurs a picture in a particular direction and at a specific intensity. The are filter’s effect is analogous to taking a picture of an moving object with a fixed exposure time.
Smart blur:- It is the useful for image and photo repair. It blur everything in the image, or selection, except the edges. It is the perfect filter when we need to take ten years off a portrait subject’s face.
. Distort filter:- Geometrically distort a image, creating 3d and other reshaping effects. It makes the picture look like it is going down the drain, melting or being blown off the page. Distort filters are:-
- Ocean ripples.
Ocean ripples:- Add randomly spaced ripple to the image surface, making the image look as if it were under water.
Pinch:- It squeezes the selection. A positive value up to 100% shifts a selection towards its center. A negative values up to-100% shifts a selection outward.
Sheer:- This filter a distorts a image along a curve. Specify the curve by dragging the line in the box to form an curve for the distortion. We can adjust any point along the curve.
Twirl:- Rotates an selection more sharply in the center than at the edges. Specifying an angle produces an twirl pattern.
Noise filter:- Noise filters can create unusual texture or remove problem areas, such as dust and scratches from an image. This helps to blend a section in to the surrounding pixels. Noise filter includes the following features:-
A. Add noise.
- Dust and scratches.
Add noise:- It applies random pixels to an image, simulating the effect of shooting pictures on high speed film. It can also be used to reduce banding in feathered selections or to give a more realistic look to heavily retouched areas.
Despeckle:- It detects the edges in an image and blurs all of the selection except those edges.
This blurring removes noise while
c) Dust and scratches:-
Dust and scratches:- It reduces noise by changing dissimilar sharpening the image and hiding defects, try various setting or apply the filter on selected in the image.
Sketch filter:-pixels. To achieve a balance between combinations of radius and threshold
Add texture to image, often for a 3d effect. These filters are also useful for creating a fine arts or hand-drawn look. Many of the a sketch filters use the foreground and background color as they redraw the image. Sketch filter include following:-
- Bas relief.
- Graphic pen.
Bas relief:- This option transforms an image to appear carved in low relief and lit to accent the surface variations. Dark areas of image take on the foreground color, light color use the background colors.
Graphic pen:- It uses fine, linear ink strokes to captures the details in the original image and is especially striking with scanned images. The filter replace color in the original image using the foreground color for ink and background color for paper.
- Photocopy:- It simulates the effect of photocopying an image. Large areas of darkness tend to copy only around their edges and midtones all away to either solid black or white.
Stamp:-It is used with black and white images. The filter simplifies the image to appear stamped with the rubber or would stamp.
Texture filter: Use the texture filters to give an image the appearance of depth or substance, or to add organic look. We can use the following filters on the images:-
- Patch work.
- Stained glass.
Patch work:- It breaks up an image into squares filled with the predominant color in that area of the image. The filters randomly reduce or increase the tile depth to replicate the highlights and shadows.
Stained glass:- Stained glass repaints an image as single colored adjacent cells outline in the
Texturizer option applies a texture that we select or create to an image.
. Other filters:- The filter in the others sub menu enable us to create own filters. We can modify mask, offset a selection within an image, and make quick color adjustment. The other filters are:-
- Minimum and maximum.
Custom option lets us to design our own filter effect. With the custom filter, we can the brightness values of the pixels in the image. Each pixels is reassigned a value based on the values of surrounding pixels. We can save the custom filter and use them with other Adobe Photoshop images.
b) Minimum and Maximum:-
The minimum filter has the effect of applying a spreading out black areas and shrinking white areas. Maximum filter has the effect of applying a choke spreading out wide areas and choking in black areas. These are useful for modifying mask.
It moves the selection a specified horizontal or vertical amount, leaving an empty space at the selection’s original location. We can the empty area with the current background color, with another part of image, or with your choice of fill if the selection is near edge of an image.
