Improvement on BMP, with smaller file size Small file size, few colors, no transparency, little compression The following table lists common picture file formats, their uses, and their advantages. Before you change the resolution of your picture, make sure you use a file format that is appropriate for the content of the image. If you plan to use the pictures online only (on the Web or in PowerPoint, for example), the pictures need to have a resolution of only 96 ppi, which is the screen resolution of computer monitors.įile format can also affect file size. You can have a higher resolution - up to 800 ppi - but you should not have a lower resolution. If you plan to have color pictures printed by a commercial printer, your picture resolution should be between 200 ppi and 300 ppi. The Effective Resolution field displays the resolution in dots per inch (dpi). In the Graphics Manager task pane, under Select a picture, click the arrow next to the picture with the info you want, and then click Details. To find the effective resolution of a picture in your publication, do the following: For example, a picture with an original resolution of 300 ppi that has been scaled 200 percent larger has an effective resolution of 150 ppi. Find the effective resolutionĮvery picture in your publication has an effective resolution that takes into account the original resolution of the graphic and the effect of scaling it in Publisher. Pictures with a resolution higher than 1,000 ppi may not print at all. If the picture resolution is too high, the file size of the publication becomes unnecessarily large, and it takes more time to open, edit, and print it. If your picture resolution is too low, the picture will have a blocky, or pixilated, appearance. Reducing the dimensions of a picture increases its resolution (more ppi). Enlarging a picture decreases the resolution (fewer ppi).
If you want more details to appear as you enlarge your picture, you need to start with a picture that has more pixels, or a higher effective resolution. These terms are often used interchangeably. The resolution of a picture is expressed in pixels per inch (ppi) or dots per inch (dpi). A picture contains the same amount of information, or number of pixels, whether you scale it larger or smaller in your publication. Graphics created by a paint program, a scanning program, or a digital camera are made up of a grid of differently colored squares called pixels. That's why it is good to know what you need before you start and find the best match.
But sometimes a graphic can't be reduced or enlarged enough to fit your needs. You can change the size and resolution of graphics-usually with good results. If you use an animated picture in an online publication, give it a clear purpose (for example, show a sequence of your product in use). Gratuitous animation risks stopping your potential customers in their tracks - they may become so distracted that they miss the point. Motionless Animation grabs the eye and doesn't let it go. By using images to show someone using your product or service, you help readers to see how it works and to envision themselves using it. Portraits of people will draw readers' attention, especially if the images are relevant and tell a story. Human Most people like to look at other people. You can also apply the same filter effects to each image, or you can use the same human models in a progressing story line. For example, you can use a small palette of colors or a single accent color, a common graphic style, the same camera angle or point of view, or consistent lighting. You can give pictures a consistent look in several ways. Because readers skim pages by reading headlines and picture captions, you can help readers glean your most important messages by reinforcing messages with pictures and brief descriptions.Ĭonsistent Unify your publication with your choice or treatment of pictures.
