While using Photoshop, a time can come when you need to work on the resolution or size of an image. You might want to
Photoshop - powerhouse that it's - enables you to size an image in each one of these ways using the Image Size command on the Image menu. Adopt these measures to resize your image: Open the image and then choose Image - Image Size. The Image Size dialog box opens. This is when the special moment happens.
Note the present state of your image and choose whether any of the following values need to alter in order to get a nicelooking image for that desired output (print or even the Web):
The present pixel dimensions and also the resulting file size: My example shows 720 pixels in width and 960 pixels in height for any file size 1.98MB (megabytes).
The present document size: How big your image if this prints on media, for example paper.
The resolution: My example is 72 ppi, that is great for displaying onscreen or on the Web, but inadequate for printing. I'll see some pixelation (visible little squares) on my small printout. Therefore, to print, I need to lessen the dimensions of the image so that my total pixels are packed right into a smaller area, to provide the image cleaner lines.
Make sure the Constrain Proportions check box is selected. The chain-and-bracket icon in the Document Size area indicates that the Constrain Proportions check box is selected. Nine times from ten, you would like your image to remain proportional. Using the option selected, changing one value in the Document Size area helps make the other values change automatically so that the proportions stay intact.
You can also choose the Scale Styles check box, that allows you to definitely scale or otherwise scale any effects or styles that you've put on your layer(s). This method can be obtained only if you select Constrain Proportions. Make sure that the Resample Image check box is deselected. Whenever you resample, you add or delete pixels in the image. Even though you sometimes need to resample, doing this is detrimental for your image.
Enter any new values in the dialog box. For instance, because I wish to print my image, I enter a brand new worth of 300 pixels per inch for my resolution in the Document Size area. Another values automatically change. Click OK. You will not notice any difference in the way your image appears onscreen since you haven't added or deleted any pixels; you've merely compacted them right into a smaller space. Congratulations! You've just safely resized your image. You can proudly say, "No pixels were harmed in the making of the image."
