Even those people who only begin to understand work with images can make manipulations and changes of images with simple devices and functions. If before you there was a question how to enlarge the small image without loss of quality, then you will be helped by an interpolation method.
How to enlarge the image without loss of quality in the Photoshop program?
At once it should be noted that it is almost impossible to enlarge the image in the Photoshop in general without loss of quality, kind of there was no wish for it. Some losses in the clearness and expressiveness of lines nevertheless will be. However these shortcomings can be corrected by means of the editor.
At bicubic interpolation the pixels do not share budding, in the course of change of the size there is their recalculation on the algorithm put in the program. That is, after increase in permission the clear boundary will look slightly indistinct as a small black-and-white gradient.
While you make manipulations to increase the image size without loss of quality, the graphic editor creates additional pixels on the basis of values next. In other words, when one pixel black, and another white, the program calculates average value and creates new pixel of gray color.
The step-by-step instruction how to increase resolution of the image without loss of quality, will look as follows:
- Having opened the editor, it is necessary to guide the mouse cursor at the Resample Image function (interpolation).
- In the appeared list it is necessary to choose a way of increase, each of which approaches a certain type of pictures.
- Further it is necessary to pass into the Change Mode menu (Image - Image Size).
- In this menu the percentage increase in the document is chosen.
- We recommend to enlarge the image gradually. For example, for a start it is worth putting value of 110%, further on ascending to the necessary parameter.
Gradual increase in the picture gives the chance to achieve good results.
Answering a question how to enlarge the image without loss of quality, it is important to consider type of the picture and its initial parameters. The quality of the source code is higher, the enlarged image will be better.
In the mode of Interpolation several types of processing of the source code are offered:
- Nearest Neighbor (on the next pixels) gives the weakest quality and it is not recommended for work with photos;
- Bilinear (bilinear) – quality is better due to calculation of average value of the next pixels;
- Bicubic (bicubic) works with a large number of the next sections and makes difficult calculation with creation of new pixels;
- Bicubic Smoother (bicubic is more smooth) – function is present at the version of Photoshop CS and differs in the best quality of work with increase in photos.
