Adobe Photoshop is photo editing software tool. You an develop images for webpage, PowerPoint presentation, or a document to be printed, Photoshop can be used to enhance your images. Photoshop is equipped with high-quality features which are easy is use. many version of adobe application are introduce by Adobe Adobe Systems Incorporated.
Photoshop is equipped with high-quality features and with help of these features we can enhance our images for example provide various Filter effect which are apply with some click also provide blending mode which can help blend different layers. Photoshop uses more then one color models like that RGB, lab, CMYK, grayscale, binary bitmap, and duotone which can help in developing the images for printing and for web. Photoshop has the ability to read and write raster and vector image formats such as .EPS, .PNG, .GIF, and .JPEG. Photoshop has ties with other Adobe software for media editing, animation, and authoring. The advanced Adobe version also provide sport to windows touch devices. A number of UI improvements make the Fill dialog more intuitive and easier to use.
A layer is simply one image stacked on top of another. You can see through transparent areas of a layer to the layers below. Each layer edited independently of each other. and then later combined to form a single, flat image. When you first create an image, you will be working with the €œBackground € layer. You cannot always use all effects on a background layer, so you may wish to start working directly with normal layers. All layers have opacity sliders, so that you can allow the background or underlying layers to show through. You can "lock layers" together, and a single effect will apply to all layers locked together this way. A layer is transparent until you paint something on it, but once it contains pixels, you can confine editing to only that artwork by selecting "Preserve Transparency" in the Layers Palette.
You can use up to 100 layers, depending on computer memory. When you create a new document in Photoshop, it has only one layer which is background layer. It's like the canvas of a painting. It can't be edited or moved up within the layer hierarchy unless you first convert it to a layer. Double click on layer and give the layer name and then save it. so its convertd in layer. When we create a new document then you can select create image with Transparent option in the New dialog box.
if you want to create a new layer in adobe Photoshop then:
Click on the new layer icon on the bottom of the Layers Palette. Or you can use the Layer Menu by selecting New Layer. You can create a layer from a selection by first making the selection, then Select Layers Menu and then select New Layer and select Layer via copy or Layer via cut.
You can also create new layers by pasting or by using the text tool.
Images with layers, or images with no backgrounds, can be stored only in Photoshop project file as .PSD file . Having layers adds to the size of the document, as the information for each must be stored independently. The storage requirements for each layer are proportional to the amount of pixel information on the layer. Transparent areas to not count.
You can also merge more then one layers together to help keep the file size down, while you continue working on the document. When finished, you should merge all layers into a "flattened image" containing only one layer.
In Adobe Photoshop the clone stamps, healing brush and patch tool are powerful tools that can be magic. Also the Rubber Stamp is also used of the retouching tools.

Set some option such that: Amount: The degree (up to 500%) with which you want to sharpen the image. The higher the value, the more dramatic the effect. Values between 25 and 50% generally produce subtle effects. Between 50 and 300% are more pronounced.
Radius:The thickness of the sharpened edge. The higher the value, the more contrast.For on-screen images such as web graphics, 0.5 results in fine, crisp edges. For printing, with a resolution of from 120 to 180 dpi, use a value of 1.0.
Threshold :The value, from 0 to 255, is the brightness value . The lower the value, the lower the threshold, and they will be considered different and sharpened.
Adjust the tonal range using Image> Adjustments> Levels.
Its help to improve the photo highlights, shadows and midtones . you can also use automatic way to do this by selecting Image menu and then Adjustments and then Auto contrast. if you want to set manually then select the level and adjust the values.
in Photoshop a panel which store the color information in the form of layers of Photoshop document is called channels. In RGB color mode panel will show 4 channel by default for red, green and blue and for CMYK mode panel will show 5 channel by default cyan, magenta, green and black.
Composite Channel:
When you show the channel panel from window then very fist section on the top of channel layer is combination of all the channels present in your channel panel. When you are working on RGB mode, then by default it will be renamed as RGB and if you are working on CMYK mode, it will be renamed as CMYK.
Color Channels:
The information of each color of the selected mode is display in these channel. For example in RGB Mode red channel stores the information of red color value present in your photo in the scale of 0 to 255 and other two White area shown the amount of red color present. The area that appears to be brighter/whiter contains more red color as compared to the area which is relatively darker. show the Green and Blue color values.
When we need to make some parts of image layer invisible then we use masking. the main advantage of masking is we can make something invisible but still be able to make it visible again at any time.
