What is Raster? What is Vectors? What Destructive and Non-Destructive is using for in Photoshop

One would think that destructive editing means that you destroy your image.But in most cases, the images will improve. Destructive editing refers to the way in which the pixels of the digital photograph are manipulated. An example of destructive editing is when one makes changes to a photograph as part of a digital editing process that is destructive. This is when you actually make permanent changes to the pixels. Darkening an area of the image, the pixels within the image will be changed to become darker. When the image is then saved, those darkened pixels will be written into the image permanently and cannot be returned to their original state. The original state of the pixels is considered to have been destroyed and this process is called“destructive editing”.

Now that destructive editing is described, Non-Destructive editing is the actual opposite of destructive editing. Non-destructive editing is a process in which the editing software does not change the pixels within the digital photograph. The following explanation describes how it is done. It is done by exporting an adjusted version of the photograph, you end up with two copies; the original and the adjusted version. This way the original photograph is still intact along with its sidecar file that has all the adjustments you made listed as nothing more than a set of instructions. If you wish, you can reset the original image back to its original state simply by telling the software to delete the set of instructions it holds in the sidecar file. Additionally, and this is one of the huge advantages of a non-destructive workflow, you can tweak the adjustments listed in this sidecar file and produce several copies of the original file.

Destructive editing software can be used with the following software; photoshop, Adobe photoshop Elements; Serif Photo Plus and Paintshop Pro. To get more information about destructive editing and non-destructive editing Go Here.

Non-destructive Editing Software is generally used with Adobe Lightroom, Adobe Camera Raw, Aperture, and Bibble.Let’s say you have a photograph and you can’t decide between a color version or a black and white version.Using a non-destructive workflow, it becomes easy to export two copies of the original photograph; one in color and one in black and white. If you take a look at our article on color or black and white you will see an example of exporting different versions of the same file. The original article will not be changed. The client will be given different copies to look at and then will be able to choose the version they like. The word “vector” is another word for a line. They are made up of mathematically-geometric shapes. When creating a vector image in a vector illustration program, node or drawing points are inserted and lines and curves connect notes together. This is the same principle as “connect the dots”. Each node, line, and a curve is defined in the drawing by the graphics software by a mathematical description. They usually are easily modified within the creating application and generally are not affected detrimentally by scaling enlarging or reducing their size. If the image is increased in size, the equation is recalculated accordingly resulting in the image increasing in size with no loss of data or detail. A vector object will have a “wireframe” underneath the colors in the object. In a vector object, colors are like clothes over the top of a skeleton.  When creating a vector image in a vector illustration program, points are inserted and lines and curves connect notes together.  If the image is increased in size, the equation is recalculated accordingly resulting in the image increasing in size with no loss of data or detail. A vector object will have a “wireframe” underneath the colors in the object.  They’re defined as solid objects and can be moved around in full, or grouped together with other objects. The advantage of using the vector is the image never changes no matter how large or how small the font is changed. The disadvantage of using vector is the compatibility. For example, Vector images are saved using adobe illustrator, which are not always available.

Rasterized graphics are explained as a collection of dots called pixels. Each pixel is a tiny square with assigned color value. They are created using a grid of pixels to make the image. When you attempt to increase the size of an image created in a raster based program, the pixels defining the image can be increased in either number or size. When you Increase the number of pixels or making the pixels bigger in an image causes the image to spread over a larger area. Spreading the pixels over a larger area causes the image to begin to lose detail and clarity. When an image is scanned, the image is converted to a collection of pixels called a raster image. Scanned graphics and web graphics are the most common forms of raster images. To get more information about vector and rasterize Go Here.
