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.
