The easiest way to enlarge or reduce the image is to make sure that Constrain Proportions is checked at the bottom of thedialog box, and then simply enter new percentages in one of the fields and click OK. As if by magic, the other numbers will change togive you the correct percentage of enlargement or reduction. For now, ignore Resample Image. Leave it set to Bicubic. You'll get intowhat this means when you need to know it in Hour 23, "Printing and Publishing."Scale Styles is a very helpful feature if you have applied a style such as a drop shadow or embossing to text or an object in your picture.Scale Styles makes sure that the size of the shadow, or the height of the embossing, remains proportional to the rest of the picture.Leave it checked.As you make changes in the Image Size dialog box, Photoshop will automatically update the file size at the top of the dialog box.Resizing a CanvasResizing the canvas to a larger size gives you extra workspace around the image; it does not change the size of the image. Becauseresizing uses the current background color to fill in the added space, be sure that it's a color you want. I always resize with white as thebackground color. Resizing the canvas to a smaller size is another way of cropping the picture by decreasing the canvas area. It's notrecommended because you could accidentally lose part of the picture and not be able to recover it.To resize the canvas, choose Image Canvas Size and specify the height and width you want the canvas to be in the dialog box(see Figure 4.2). You can specify any of the measurement systems you prefer on the pop-up menu, as you saw in the Image Size dialogbox earlier. Photoshop calculates and displays the new file size as soon as you enter the numbers.Figure 4.2. The Canvas Size dialog box.
