This is a photo that has been edited as a effect, using a Gaussian blur. Image editing encompasses the processes of altering, whether they are, traditional,.
Traditional analog image editing is known as, using tools such as an to modify photographs, or editing illustrations with any traditional. Programs, which can be broadly grouped into, and, are the primary tools with which a user may manipulate, enhance, and transform images. Many image editing programs are also used to or create from scratch. Contents. Basics of image editing images are stored in a computer in the form of a grid of picture elements,.
These pixels contain the image's color and brightness information. Image editors can change the pixels to enhance the image in many ways. The pixels can be changed as a group, or individually, by the sophisticated within the image editors. This article mostly refers to graphics editors, which are often used to alter photographs and other raster graphics. However, software, such as, PixelStyle Photo Editor, or, are used to create and modify vector images, which are stored as descriptions of, and instead of pixels. It is easier to a vector image than to a raster image; how to go about vectorizing a raster image is the focus of much research in the field of. Vector images can be modified more easily, because they contain descriptions of the shapes for easy rearrangement.
They are also scalable, being rasterizable at any. Automatic image enhancement Camera or computer image editing programs often offer basic automatic image enhancement features that correct color and brightness imbalances as well as other image editing features, such as removal, adjustments, features and automatic. These are called automatic because generally they happen without user interaction or are offered with one click of a button or mouse button or by selecting an option from a menu.
Additionally, some automatic editing features offer a combination of editing actions with little or no user interaction. Digital data compression Many image file formats use to reduce file size and save storage space. Digital compression of images may take place in the camera, or can be done in the computer with the image editor.
When images are stored in format, compression has already taken place. Both cameras and allow the user to set the level of compression. Some compression algorithms, such as those used in file format, are lossless, which means no information is lost when the file is saved.
By contrast, the file format uses a compression algorithm by which the greater the compression, the more information is lost, ultimately reducing image quality or detail that can not be restored. JPEG uses knowledge of the way the human brain and eyes perceive color to make this loss of detail less noticeable. Image editor features Listed below are some of the most used capabilities of the better graphic manipulation programs. The list is by no means all inclusive. There are a myriad of choices associated with the application of most of these features.
Selection One of the prerequisites for many of the applications mentioned below is a method of part(s) of an image, thus applying a change selectively without affecting the entire picture. Most graphics programs have several means of accomplishing this, such as:.
a marquee tool for selecting rectangular or other regular polygon-shaped regions,. a for freehand selection of a region,. a that selects objects or in the image defined by proximity of color or,. vector-based pen tools, as well as more advanced facilities such as, and color and channel-based extraction.
The border of a selected area in an image is often animated with the effect to help the user to distinguish the selection border from the image background. Main article: Another feature common to many graphics applications is that of, which are analogous to sheets of transparent (each containing separate elements that make up a combined picture), stacked on top of each other, each capable of being individually positioned, altered and with the layers below, without affecting any of the elements on the other layers. This is a fundamental workflow which has become the norm for the majority of programs on the market today, and enables maximum flexibility for the user while maintaining principles and ease of use. Image size alteration Image editors can resize images in a process often called, making them larger, or smaller. High cameras can produce large images which are often reduced in size for use. Image editor programs use a mathematical process called to calculate new pixel values whose spacing is larger or smaller than the original pixel values.
Images for Internet use are kept small, say 640 x 480 pixels which would equal 0.3. Cropping an image. Main article: Image editors may feature a number of algorithms which can add or remove in an image.
Some artifacts can be removed; dust and scratches can be removed and an image can be de-speckled. Noise reduction merely estimates the state of the scene without the noise and is not a substitute for obtaining a 'cleaner' image. Excessive noise reduction leads to a loss of detail, and its application is hence subject to a trade-off between the undesirability of the noise itself and that of the reduction artifacts. Noise tends to invade images when pictures are taken in low light settings. A new picture can be given an 'antiqued' effect by adding uniform monochrome noise. Perspective control: original (left), perspective distortion removed (right).
Some image editors allow the user to (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 distortion which results from photographs being taken at an to a subject. Care is needed while performing this task, as the image is reprocessed using of adjacent pixels, which may reduce overall image.
The effect mimics the use of a, which achieves a similar correction without loss of definition. Lens correction Photo manipulation packages have functions to correct images for various lens including pincushion, and barrel distortions. The corrections are in most cases subtle, but can improve the appearance of some photographs. Enhancing images In, the process of improving the quality of a digitally stored image by manipulating the image with software. It is quite easy, for example, to make an image lighter or darker, or to increase or decrease contrast. Advanced photo enhancement software also supports many filters for altering images in various ways.
Programs specialized for image enhancement are sometimes called image editors. Sharpening and softening images Graphics programs can be used to both sharpen and blur images in a number of ways, such as. Portraits often appear more pleasing when selectively softened (particularly the skin and the background) to better make the subject stand out. This can be achieved with a camera by using a large, or in the image editor by making a selection and then blurring it. Is an extremely common technique used to make images appear sharper, although purists frown on the result as appearing unnatural. Image Sharpening: original (top), Image Sharpened (bottom). Another form of image sharpening involves a form of contrast.
This is done by finding the average color of the pixels around each pixel in a specified radius, and then contrasting that pixel from that average color. This effect makes the image seem clearer, seemingly adding details. An example of this effect can be seen to the right. It is widely used in the printing and photographic industries for increasing the local contrasts and sharpening the images. Selecting and merging of images.
Photomontage of 16 photos which have been in to give the impression that it is a real landscape Many graphics applications are capable of merging one or more individual images into a single file. The orientation and placement of each image can be controlled. When selecting a raster image that is not rectangular, it requires separating the edges from the background, also known as silhouetting. This is the digital analog of cutting out the image from a physical picture. May be used to add silhouetted images to vector graphics or page layout files that retain vector data., allows for soft edges when selecting images. There are a number of ways to silhouette an image with soft edges, including selecting the image or its background by sampling similar colors, selecting the edges by raster tracing, or converting a clipping path to a raster selection.
Once the image is selected, it may be copied and pasted into another section of the same file, or into a separate file. The selection may also be saved in what is known as an. A popular way to create a composite image is to use transparent. The background image is used as the bottom layer, and the image with parts to be added are placed in a layer above that. Using an image, all but the parts to be merged are hidden from the layer, giving the impression that these parts have been added to the background layer. Performing a merge in this manner preserves all of the on both layers to more easily enable future changes in the new merged image. Slicing of images 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. A complex effect in the first image from the right. 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. Also, there is a choice between Clone align or Clone non-align the sample area. In Photoshop this tool is called Clone Stamp, but it may also be called a Rubber Stamp tool.
An example of converting an image from color to grayscale It is possible, using software, to change the of images. Common color depths are 2, 4, 16, 256, 65,536 and 16.7 million colors.
The JPEG and PNG image formats are capable of storing 16.7 million colors (equal to 256 luminance values per color channel). In addition, images of 8 or less can be created, usually via conversion and from a full-color image. Is useful for reducing file size dramatically when the original photographic print was monochrome, but a color tint has been introduced due to aging effects.
An example of contrast correction. Left side of the image is untouched. Image editors have provisions to simultaneously change the and brighten or darken the image. Can often be improved by using this feature. Recent advances have allowed more intelligent exposure correction whereby only pixels below a particular threshold are brightened, thereby brightening underexposed shadows without affecting the rest of the image. The exact transformation that is applied to each color channel can vary from editor to editor.
Applies the following formula. Main article: In addition to the capability of changing the images' brightness and/or contrast in a non-linear fashion, most current image editors provide an opportunity to manipulate the images'.
Gamma correction is particularly useful for bringing details that would be hard to see on most computer monitors out of shadows. In some image editing software this is called 'curves', usually a tool found in the color menu, and no reference to 'gamma' is used anywhere in the program or the program documentation.
Strictly speaking, the curves tool usually does more than simple gamma correction, since one can construct complex curves with multiple, but when no dedicated gamma correction tool is provided, it can achieve the same effect. Color adjustments. An example of color adjustment using raster graphics editor 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 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 incorrectly set. Special effects, like and grayscale, can be added to an image.
In addition, more complicated procedures such as the mixing of color channels are possible using more advanced graphics editors. The, which occurs when flash photos are taken when the pupil is too widely open (so that light from the flash that passes into the eye through the pupil reflects off the fundus at the back of the eyeball), can also be eliminated at this stage. Before and After example of Advanced Dynamic Blending Technique created by Elia Locardi Advanced Dynamic Blending is a concept introduced by photographer in his blog to describe the photographic process of capturing multiple bracketed exposures of a land or cityscape over a specific span of time in a changing natural or artificial lighting environment. Once captured, the exposure brackets are manually blended together into a single High Dynamic Range image using post-processing software. Dynamic Blending images serve to display a consolidated moment. This means that while the final image may be a blend of a span of time, it visually appears to represent a single instant. Printing.
Control printed image by changing pixels-per-inch. Controlling the print size and quality of digital images requires an understanding of the (ppi) variable that is stored in the image file and sometimes used to control the size of the printed image. Within 's Image Size dialog, the image editor allows the user to manipulate both pixel dimensions and the size of the image on the printed document.
Video Enhance Software
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.
Pixel Enhance
The Image Size dialog can be used as an image calculator of sorts. For example, a 1600 × 1200 image with a resolution of 200 ppi will produce a printed image of 8 × 6 inches. The same image with 400 ppi will produce a printed image of 4 × 3 inches. Change the resolution to 800 ppi, and the same image now prints out at 2 × 1.5 inches. All three printed images contain the same data (1600 × 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.
