Introduction of Photoshop

Adobe Photoshop is an extremely powerful application that’s used by many professional photographers and designers. You can use Photoshop for almost any type of image editing, from touching up photos to creating high-quality graphics. Photo editing can be used to enhance exposure, remove and add unwanted objects, colour editing of image.

Features of Photoshop

Photoshop has so many features that it may actually be too powerful for many users. Most of photo editing features are listed below, take a look.

  1. Selection: It is an area of a photo that you can define. When you create a selection, the area i editable (for example, you can lighten one part of a photo without affecting the rest), thu applying a change selectively without affecting the entire picture.
  2. Layers: In Photoshop, layers are used to work on individual parts of an image while not affecting other parts. You might say that layers are like transparency papers stacked on top of one another which can be repositioned and separately drawn on without disturbing each other. You move a layer to position the content on the layer.
  3. Image size alteration: Image editors can resize images in a process often called image scaling making them larger or smaller. High image resolution cameras can produce large images which are often reduced in size for Internet use.
  4. Cropping: Cropping is the process of removing portions of a photo to create focus or straighten the composition. Use the Crop tool to crop and straighten photos in P.* Photoshop.

  5. Histogram: Image editors have provisions to create an image histogram of the image being edited. The histogram plots the number of pixels in the image with a particular brightness value. Algorithms in the digital editor allow the user to visually adjust the brightness value of each pixel and to dynamically display the results as adjustments are made. Improvements in picture brightness and contrast can thus be obtained.
  6. Selective color change: Some image editors have color swapping abilities to selectively change the color of specific items in an image, given that the selected items are within a specific color range.
  7. Stamp Clone Tool: The Clone Stamp tool selects and samples an area of your picture and then uses these pixels to paint over any marks. The Clone Stamp tool acts like a brush so you can change the size, allowing cloning from just one pixel wide to hundreds. You can change the opacity to produce a subtle clone effect. In Photoshop this tool is called Clone Stamp, but it also be called a Rubber Stamp tool.
  8. Color adjustments: The color of images can be altered in a variety of ways. Colors can be faded in and out and tones can be changed using curves or other tools. The color balance can be improved, which is important if the picture was shot indoors with daylight film or shot on a camera with the white balance incorrectly set.
