LESSON 1: Parts of Photoshop

The first step to build your career in image editing is to familiarize yourself in the different elements of photoshop.

Opening the Application

The first step, of course is to open the Photoshop. Once you've opened it click on the file and then select new.
You can select your desired size and filename to start editing. After a couple of seconds your document will appear. You would see lots of objects on your screen,
and if you think you dont need some of the elements, just click on the window to select and deselect them.


The workspace

Toolbar


The most important part is the toolbar.It contains a bunch of icons that represent the different tools Photoshop offers to alter and create images.
These include tools for selecting specific areas of images, changing the colors of the image, stretching, transforming, and erasing parts of an image, and many more.
To get an idea of what some of these tools can do, mouse over the icons and you�ll get an explanatory tool tip.














Panes are also important features of the Photoshop interface. All sorts of information is displayed in these panes, and therefore they can get a little
confusing. They display location information, tool options, and history, among other things. If you ever lose track of a specific pane (they tend to stack up), go
to the windows menu and select that pane to view it. I�ll talk more about the specific panes later on in the tutorial.


Various Photoshop Panes

Menus are probably the most familiar interface elements to a new Photoshop user. They contain all sorts of options, but since there are not as visible as panes
or the toolbar, they are often only partially explored. I�ll take time right now to go over the menus and give a brief description to orient you to each.


1.File contains all of the stuff you�d expect it to, with a few extras including Import, which deals with scanning, and Save for Web, which allows
you to export a web-ready image from your Photoshop file.

2.Edit is another familiar menu. In Photoshop, edit houses all of the expected options as well as Fill & Stroke, and other image-altering functions.

3.Items on the Image menu effect a whole image, for the most part. Here you�ll find color adjustments, size adjustments, and any other changes
you need to make globally when working with a Photoshop file.

4.The layer menu is similar to the image menu, but it contains options that effect only current or selected layers. I�ll explain layers a little later, but for now,
just understand that an image in Photoshop consists of stacked transparent layers; options in the Layer menu affect these pieces of the image rather than the complete
image.

5.The select menu deals with selections you make. Selecting the specific parts of an image you�d like to alter is a difficult part of working in Photoshop.
This menu gives you some options regarding selections, including the ability to save selections, reverse them, or add to them. Learning the options on the selection menu
can really save you some time.

6.The filter menu is probably what most people think about when they think about Photoshop. The filter menu allows you to apply filters to any part of your image.
These filters include ways to change the texture of the image, with some potentially radical results.

7.The view menu is where you change the view settings. You can use this to show and display guidelines on the image, and to zoom in and out, among other things.

8.The window menu allows you to toggle back and forth between hide and show for each interface element. This is the first place you should go if you lose track of a particular
window while you�re working.

9.Last and least, of course, is the help menu. The help documentation isn�t so helpful, but for some reason, this menu contains two nice features: resize image,
and export transparent image, which I�ll get to later.

TOOL BOX It is the main component of photoshop which include all the useful photo editing tools like selection tool.move tool,crop tool,brush,pen,eraser etc.

DRAWING CANVAS It present in the center of PS where all the photo editing takes place.like whatever photo you want to edit will open in this drawing
canvas window where you can edit it with the
help of various tools available in photoshop.

PALETTES Each �panes� that carry options for working with your file in PS, known as palettes (also known panels), It float on the right-hand side of PS window.
Each palette is tagged with a tab, and can be minimized, closed, grouped with other palettes, or dragged in and out of a panel dock available in PS.

Some definitions to get you started:

.psd: A .psd file is the file format in which Photoshop saves documents by default. It is a multi-layer document that retains its full editing options when saved.
In many cases you will export webgraphics from a .psd document.

Layers: Photoshop documents are composed of layers, which can basically be described as single transparent sheets which hold particular pieces of an image.
These layers can contain images, text, and vector graphics, and can be rearranged and grouped according to user needs. Layers are controlled with the use of the Layers pane.
Often times, when you find yourself frustrated with Photoshop, it is because you are trying to perform operations on a layer that is not currently selected. Simply click on the name of
a layer in order to designate it as the current layer.
Whenever you add text to an image in Photoshop, the text appears on a new layer. You can "merge down" layers to consolidate them, and "flatten image"
to force the entire contents of the image onto one layer.

Selections: Selections refer to regions in an image that will be affected by the various tools. A selection in Photoshop is similar to a selection that you
highlight in a wordprocessing application. Once you have selected an area, you can apply a tool to it, such as paintbrush, or perform an operation such as copy or crop.
Selections can be any shape and size; the shape depends on which selection tool you are working with.

Your selection will apply only to the current layer. If that layer is empty in the region selected, you will get an error message. When this happens, go to the layers pane and select the correct layer.

Resolution: Resolution refers to the number of pixels in a full size image. An image with hi resolution contains more information than an image with lo resolution,
and therefore, one can always convert a hi-res image to a lo-res image. However, because information is lost in the conversion, the reverse is not true.
If you were to increase the resolution of a lo-res image, the result would be fuzzy.

Screen resolution is close to 72 pixels per inch, so if you are working with graphics to be viewed only on screen, 72
should be fine. Depending on the printer you are using, you would want to increase this above 72 for graphics
that will be printed. 300 is usually an acceptable resolution for images to be printed; 150 would be the lowest acceptable resolution for printing.

Image Size: Resolution should not be confused with image size, which is also expressed in pixels. Image size deals with the actual number
of pixels tall and wide an image is. For an idea of how the two differ, go to Image Size in the Image menu, and plug in different numbers for image size and resolution.

Color mode: Color mode refers to the types of colors you will be using in your image. CMYK and RGB are the most important of these modes to be familiar with.

CMYK is the setting for images that will be printed to paper. The letters refer to the four channels of color used to create every color available: cyan, magenta, yellow, and black.


RGB refers to the three channel colormode suitable for images to be viewed on the web: red , green, and blue.
