Enable you to create special effects, repair images,enhance images, Create artwork, Add lighting effects, Repair damage Improve sharpness, and Soften harsh details.
Filters can be found under the Filter Menu on the menu bar once the pull down menu appears you can preview image , while applying the filters in the filter gallery.
Perhaps a common effect that people use to bloat up their enemies images is the liquefy tool (Shift +Ctrl/ Command +X). Well that is all filters
These tools are common in all photo editing applications. In Photoshop the tool panel is at the left of the Photoshop window. The tools in Photoshop we learnt this week are Painting tools, Selection tools, Navigation tools and Erasers.
The Selection tools include the Marquee tools, Lasso tools, Quick selection, you can select the tools by clicking on their icons/ symbols or use key board shortcuts.
Marquee tools=======> Control(or Command) + M
Lasso tools =========>Control(or Command) + L
The move tool=======>Control(or Command) + V
Quick Selection======>Control(or Command) + W
A Marque tool can be used (that is if you have selected one) by pointing your mouse over desired area and draging out upto the desired size. The tool can be rectangular. elliptical, single column (vertical line) or single row (horizontal).
The Lasso tools will help you select irregular shapes they include the lasso, polygonal and magnetic lasso tools. The lasso tool is used by clicking and dragging around the irregular shape or any kind of shape. The polygonal tools lets you create anchors while selecting around the shape/image then the magnetic tool sort of works like the polygonal tool expect it helps you automatically create anchoring points around the shape by checking difference in color pixels.
Quick Selection and Magic wand tools are used for quick selection. The magic wand selects all areas of the image with the same color as that of the area you clicked on.
The move tool can be used to move the selection or the selected area.
The tools can do more than mentioned above by using the option bar that comes up as soon as you select one of the tools. The bar includes Adding, selecting and intersecting options. This helps to add or subtract from a shape to create a new one. This option can also let you use more than one type of selection tool.
The include Brush(Brushes)(Ctrl/ Cmd +B), Pencil, (Art) History brush, Gradient, Paint Bucket , Color replacement, Mixer brush.
Photoshop has preset brush but you can download more or create your own.
Hand used to navigate an image without need of zooming or out then selecting. The Rotate view tool and Zoom tool.

For those using Photoshop to produce professional looking images and so on the following should be basic information before you start your project.
Bit: Binary digit, a digit in the binary coding system that is it is a 0 or 1, smallest or basic unit of information. A pixel on the hand is the basic unit of color on computer display It is defined as a unit of color and its location. Thus a pixel can contain one only one color and is square or (rectangular) shaped.
. 1 bit = 2 colors that is n bits = 2^n colors for example 8 bits will contain 2 to power 8 colors which is exactly 256 colors.
Other terms to be familiar with are:
A color as displayed onscreen is combination of RBG (Red Blue and Green). The intensity (percentage or how much ) of Red , Blue or Green in a color determines what color appears on the screen.
An Image (still image) on the other hand is that that depicts visual perception. Photoshop is especially used for bit-mapped images over vector graphics .
Image resolution is the number of pixels that make up a printed out inch. The higher the resolution the clearer the printed out version of the image this of course with respect to the capabilities of your printer.
Because image size ( its appearance )onscreen differs according to size of monitor zooming and out etc image size on screen is measured in pixels over manual use of your ruler to try and measure the size of the image on screen.
Print resolution: density of pixels on a printed page.
The relationship between an onscreen image and its printed out version is that:
On Screen Size/ Resolution = Printed Width
For example for an image with Screen size 200 pixels and resolution 100 pixels will be with width 2 inches. If the resolution is higher then the same screen size will be smaller once printed out .
Using the Information In Photoshop
The main purpose of knowing how many colors in a pixel or the resolution is for print out purposes to prevent the frustration of discovering that your project looks better (bigger) on screen than on your hard-copy.
Note that image resolution should be set before starting because it defines how many pixels per inch an image will have changing the image’s resolution after creating it will distort it on the hand the pixels can be changed. However while working with vector graphics this restriction is void because the image will retain its quality irrespective of the scaling direction.
