Black and White - photo usually contains pixels which vary from black through many shades of gray to white. is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color component of a single pixel. Change color depth -also known as bit depth acts like a brush so you can change the size, allowing cloning from just one pixel wide to hundreds. Stamp clone tool -selects and samples an area of your picture and then uses these pixels to paint over any marks. can be applied to an image which include various forms of distortion, artistic effects, geometric transforms and texture effects, or combinations thereof. Special effects -Images may be skewed and distorted in various ways. This is useful to allow dynamic swapping via interactivity or animating parts of an image in the final presentation. Image slicing Parts of images for graphical user interfaces or web pages are easily sliced, labeled and saved separately from whole images so the parts can be handled individually by the display medium. Perspective control and distortion It is the preferred method of correcting the typical perspective distortion which results from photographs being taken at an oblique angle to a rectilinear subject.Ĭare is needed while performing Lens correction Photo manipulation packages have functions to correct images for various lens distortions including pincushion, fisheye and barrel distortions.
Clone Tool Most image editors can be used to remove unwanted branches, etc., using this tool 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 image orientation Image editors are capable of altering an image to be rotated in any direction and to any degree. Noise reduction merely estimates the state of the scene without the noise and is not a substitute for obtaining a "cleaner" image. Histogram -plots the number of pixels in the image (vertical axis) with a particular brightness value (horizontal axis). resampling Image editor programs use a mathematical process called to calculate new pixel values whose spacing is larger or smaller than the original pixel values. image scaling -Image editors can resize images in a process often called, making them larger, or smaller. Today they are an integral feature of image editors. can be compared to a transparency on which imaging effects or images are applied and placed over or under an image. Layers -are used in digital image editing to separate different elements of an image
