The pixels we talked about earlier can be thought of as those tiles. The larger the tiles, the less detail and thus the simpler the design must be. The smaller the tiles are, the greater the detail and the more intricate the design can be. A good way to think of resolution is to think of a digital photo as a design mosaic made up of those very small tiles we mentioned earlier. What is resolution? Simply put, resolution is the amount of information contained in an image. When preparing files for printing, the problem that most people encounter with their digital pictures is resolution. If you magnified a high resolution digital image to 1,600 percent you would see the pixels (or tiles) that the image is made up of. You may find it helpful to think of it as a very small tile, such as a floor tile. A pixel's appearance can be defined as a tiny square of color. The word PIXEL is a contraction of the term PIcture ELement. All images from digital cameras or scanners are made up of PIXELS. Resloution: Let's Play the Numbers Game.Image Resolution, Printed Size, and CMYK File Size s. When we are through you will understand effective resolution and will be able to figure scale and place pictures just like a pro. Just what does that really mean? Below we will explain just what resolution is, what it looks like when printed (high and low resolution) and how it is affected when pictures are placed within a document and scaled up or down. Pictures should always be supplied at an effective resolution of 300 pixels per inch (PPI) for best results when printing on professional printing presses. Image resolution is one subject that confuses a lot of people but it is not really so difficult to understand. How They Affect the Appearance and Quality of Digital Images The use of a large computer monitor is recommended for viewing.Explaining Digital Image Resolution, Effective Resolution and Images are available for Licensing and as Prints.ġ) Thumbnails are shown below for easy navigation to a photoĢ) The photo is two forms a larger view with possible cropping (device depended) and a smaller view to show the full width (use the navigation arrows left or right)ģ) Full panning and zooming of the image to 100% - click on the images describe in point 2 to enter this view Such high resolutions are also of benefit even with creating more “normal” sized wall-mountable prints as the fine detail contributes to exceptional quality. Images of such size open up many commercial applications allowing designers to envision huge areas being covered by a single image where details can still be seen at very close viewing distances. Equally, post-production assembly work is a laborious task that can take tens of hours to complete.Īs an example, a 1,000-megapixel (1 gigapixel) image (50,000 x 20,000 pixels in dimension) is large enough to be printed 7 meters (23 feet) wide at high quality. The capturing of all the necessary images in the field can literally take hours to complete and changing weather conditions can sabotage a shoot, resulting in thousands of images on memory cards but with nothing that is worth assembling. In post-production, all of those photos are carefully and painstakingly assembled into the final gigapixel image. Each photo captures only a very small area of view but in extreme detail. To create such huge images, thousands of photos are taken of the same scene using a telephoto lens. They are meticulously created and have resolutions that are hundreds of times higher than typical photos, revealing incredible worlds of detail. Many of my images are 1 to 4 gigapixels (1,000 to 4,000 megapixels) in size and are some of the highest-quality artistic photographs ever made. Ultra-high-resolution gigapixel images are those that are near or exceed one billion pixels - 1000 times the information contained in a one-megapixel image.
