Fig. 4.1. Window Image Size

In this chapter you learn how to change image sizes and resolution, how to make the image more accurately, to change the size of a canvas, to cut off the image, to overturn and turn it.

The remark

In program Photoshop at change of image sizes to saving of current resolution (flag Resample Image (to Trace changes) is installed) there is an interpolation that worsens quality of a picture. That is why it is always better to scan or create the image of that size which is necessary to you. If interpolation is inevitable, after apply filter Unsharp Mask (a blur Mask) to raise sharpness of the image (the section «Application фильтpa Unsharp Mask» this chapter see).
