[[లేయర్లు]] అంటే ఒక దానిక్రింద ఒకటిగా ఉన్న వస్తువుల(<u>ఇక్కడ చిత్రాలు,అక్షరాలు,రంగులు ప్రత్యేక మార్పులు మొ||వి అనుకుందాం</u>) సమూహం ''ఉదా'': వుల్లిగడ్డ కాని కాబేజీ కాని అడ్డంగా కొస్తే మనకు కనిపించే పొరలు లాగ అన్నమాట.ఈ లేయర్ల వలననే మాకు కావలసినట్టు ఒక చిత్రాని కాని కొన్ని చిత్రాలని కాని మార్పులు చేర్పులు సులభంగా చేయగలం.లేయర్ల గురించి తెలీకపోతే ఇమేజ్ ఎడిటింగ్ చేయటం చాలా గందరగోళంగా ఉంటుంది.

===హిస్టోగ్రాం=== (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 (vertical axis) with a particular brightness value (horizontal axis). 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.

===నాయిస్ తీసివేత=== Noise removal
Image editors may feature a number of algorithms which can add or remove [[image noise|noise]] in an image. [[JPEG]] artifacts can be removed; dust and scratches can be removed and an image can be de-speckled. Noise tends to invade images when pictures are taken in low light settings. A new picture can be given an 'antiquated' effect by adding uniform monochrome noise.

Most image editors can be used to remove unwanted branches, etc, using a "clone" tool. Removing these distracting elements draws focus to the subject, improving overall [[Composition (visual arts)|composition]]

Image editors are capable of altering an image to be rotated in any direction and to any degree. [[Mirror image]]s can be created and images can be horizontally [[flipped image|flipped]] or vertically [[flopped image|flopped]]. A small rotation of several [[degree (angle)|degree]]s is often enough to level the [[horizon]], correct [[verticality]] (of a building, for example), or both. Rotated images usually require [[cropping (image)|cropping]] afterwards, in order to remove the resulting gaps at the image edges.

Perspective correction and distortion
Line 69 ⟶ 70:
Some image editors allow the user to [[Distortion|distort]] (or "transform") the shape of an image. While this might also be useful for special effects, it is the preferred method of correcting the typical [[Perspective (graphical)|perspective]] distortion which results from photographs being taken at an oblique angle to a [[rectilinear]] subject. Care is needed while performing this task, as the image is reprocessed using [[interpolation]] of adjacent pixels, which may reduce overall image [[definition]]. The effect mimics the use of a [[perspective correction lens]], which achieves a similar correction [[in-camera effect|in-camera]] without loss of definition.

Graphics programs can be used to both sharpen and blur images in a number of ways. Portraits often appear more pleasing when softened (particularly the background, to make the subject stand out more — this is an example of shallow [[depth of field]] which can be achieved with a camera by using a large [[aperture]], or artificially within software, by selecting the background portion of an image, and then blurring it). The [[red-eye effect]], which occurs when flash photos are taken when the pupil is too widely open (thus reflecting back the color of the blood-rich retina), can also be eliminated. [[Edge enhancement]] is an extremely common technique used to make images appear sharper, although many purists frown on the end result as less natural-looking.

===చిత్రాన్ని ముక్కలుగా కత్తరింపు===
A more recent tool in digital image editing software is the image slicer. 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. This is useful to allow dynamic swapping via interactivity or animating parts of an image in the final presentation.

Controlling the print size and quality of digital images requires an understanding of the pixels-per-inch (ppi) variable that is stored in the image file and sometimes used to control the size of the printed image. Within the Image Size dialog (as it is called in [[Photoshop]]), the image editor allows the user to manipulate both pixel dimensions and the size of the image on the printed document. These parameters work together to produce a printed image of the desired size and quality. Pixels per inch of the image, pixel per inch of the computer monitor, and dots per inch on the printed document are related, but in use are very different. The Image Size dialog can be used as an image calculator of sorts. For example, a 1600 x 1200 image with a ppi of 200 will produce a printed image of 8 x 6 inches. The same image with a ppi of 400 will produce a printed image of 4 x 3 inches. Change the ppi to 800, and the same image now prints out at 2 x 1.5 inches. All three printed images contain the same data (1600 x 1200 pixels) but the pixels are closer together on the smaller prints, so the smaller images will potentially look sharp when the larger ones do not. The quality of the image will also depend on the capability of the printer.▼
