What is filters?                                                    Filters have a good history and a filter  is a sequence of actions that leads to a change in your project. Filters also called plug-ins because you can install or uninstall it independently from Photoshop.                                                                                 Filters can Help you in multiple ways as you can use it to transform any object from one to another or you can use it to correct your images.In a deep language we can say that Photoshop filter is  a sequence of instructions that tells Photoshop what to do with a particular pixel in an image or a selection in the same image. .                                                                 

How to use Photoshop filters ?                                                           Photoshop have 13 category and 110 different filters that do many different things and we can divide filters into 2 basic categories "corrective " And "destructive filters" The corrective are used to correct any problems in your image and the destructive are used to obliterate some features of images .                                             

 

Sharpening Images:                                           Sharpening filters increase the contrast between adjacent pixels And you can see the difference between the 2 images in Figur1 You see that the edges are more obvious and the dark  areas are more darker and light areas are lighter.

 

Sharpen Edges:                                                         It is a single step filter it works mainly on the edges of the image it adds the sharpness without making any noise in the image.

Sharpen More:     It is also a ingle step fitler that concentrates its work on increasing the contrast between all pixels of the image but it doesn't give a good result in large areas.

Unsharp Mask:                                                         Although it is named unsharp mask but it does a complicated effect on the image called unsharp masking.When youopen this filter (Filter >> Sharpen >> Unsharp mask ) you willfind three sliders waiting you. The first is the A mount Slider which used to change the sharpening a mount of the image edges .IF you make the amount less than 100% you will gain the effect without making the image appear un realistic.

The second slider is the Radius slider, you can use it to  control the width of edges that the Filter will modify, you will find that the use of this control vary on the resolution of the image So low resolution image will look best   when you use a small radius value.

The third slider Determines the difference in brightness between neighboring Pixels And So Selecting a low value causes edges with very little contrast difference to be emphasized .

 

Blurring Images:If you have any image that contains unwanted roughness or noise you may need to blur the background to make the foreground more sharper . The blurring options are :

Average: This single-step filter calculates the average value  of the image or a selection and fills the area with that average value. This can be useful for smoothing the values of areas containing a lot of noise.


Blur: Also it is  a single-step filter, Blur provides overall blurring of an image.


Blur More: This filter provides a massive  increased amount of blurring than the regular, old-fashioned Blur filter.


Gaussian Blur: This filter offers a radius control to let you adjust the amount of blurring more perfectly. It’s also got a really cool name.

Lens Blur: This filter gives you  the blurring effect  that can occur when you capture an image with a camera.

Motion Blur:This filter Gives you the effect of  the blur you see in objects that are moving.
 

Radial Blur: This filter produces the kind of blur you might get when capturing  a revolving automobile tire.
 

Smart Blur: This filter lets you determine how Photoshop applies the blur to edges and the other details of the image.

 

Fading a Filter:
Sometimes you may not want the full effects of a filter applied to your image or selection. Photoshop has a handy Fade Filter facility that lets you control the intensity of the filter’s effects. You can access this feature by choosing Edit>>Fade, or by pressing Shift+Ctrl+F. The Fade Filter facility also has a Preview option so that you can preview the changes you’re making to the original image.

 

Rendering:Rendering means creating something from nothing, in a way. That’s why rendering filters in Photoshop all produce special effects by creating a look, object, or lighting effect that’s melded with your original image.

Using the Clouds filter:The Clouds filter, for example, can make a sky full of clouds from scratch with a few clicks of your mouse,  This filter creates clouds using random values from between the foreground and background colors. Indeed, most Photoshop veterans use this filter so much that they have a surprising number of clouds in their images. Find it at Filter>>Render>>Clouds. To create a more realistic cloud effect, press Alt (Option on the Mac) when choosing the command.

3D Transform: Use this filter to wrap objects around three-dimensional shapes such as cubes and spheres, producing say, a mock-up of your favorite championship breakfast cereal with your photo on the front.

Difference Clouds: Use this filter to create puffy objects in the sky (or foggy clouds at lower levels). Instead of performing this magical feat the way the Cloud filter does, the Difference Clouds filter uses image information to figure the difference in pixel values
between the new clouds and the image they’re joining. The result is a unique cloud effect. Try applying the filter repeatedly to create a marbleized effect.
 

Lens Flare: This filter creates the reflection effect that plagues photographers when they point their cameras toward a strong light source, such as the sun. Photoshop provides several different kinds of photographic lenses, giving you useful flares that can spice up concert photos, add a sunset where none existed, and create other kinds of lighting bursts. In the Lens Flare dialog box, specify a location for the center of the flare by clicking on the image thumbnail or dragging the crosshair.
 

Lighting Effects: A sort of photo studio lighting setup, this filter uses pixels to do its work. You can set up 16 different lights and manipulate how they illuminate your photo.
 

Texture Fill: This filter fills an area with a grayscale image. Select the filter and open the image you want to use as the texture fill.
