Large volumes of modern storage devices allow storing digitized images of the highest quality without compression. Nevertheless, due to the requirements for the speed of information transmission over networks and the conditions for placing images on photo hosting sites, the topic of image compression remains relevant.
Useful information and excess volume
For printing, the standard for image resolution is 300 dpi. You can determine the size of the image by loading it into Photoshop. Select the Image tab from the menu, and then the Image Size tab. In the window that opens, uncheck the Resample image function, if it is set there. By entering 300 dpi in the Resolution column, you can see the actual size of the image when it is printed. You can save the obtained parameters for the file, but you can also resize the image by turning on the Resample image function. Moreover, increasing the size even with the use of interpolation (Photoshop provides this opportunity) will not improve the image quality. Reducing the size of the image will lead to a certain loss of information and quality, but the file size will also decrease. You can use this method when posting an image on the Internet, when the image is not supposed to be printed. It is also recommended to reduce the size of the image when it is obtained by scanning with excessive resolution. If keeping the original size of the image is important, you can use other methods to reduce the size of the files.
