Understanding Resolution in Digital PhotographyOne of the most important elements of digital photography is to understand the resolution. If you don't understand, the resolutions you may only come up with wallet size pictures each time you snap a shot. A camera snapping low-resolution shots will only deliver you confusion, especially if you try to enlarge the photo. A high or medium resolution camera on the other hand, if the pixels are properly adjusted will give you a high quality photo for publishing and/or editing. Accordingly, the resolution will also determine the quality of images taken from your camera. Digital imaging works like a thousands of dots dabbled on a surface. Digital images comprise small itsy bitsy pixels in the shape of squares and in the arena of colors. The pixels are measured in inches. The pixels are also known as an element picture, or picture element. Once the pixels all come together, you can actually see what the photo offers. If you enlarge a low-resolution picture, the blurring will shock your eyes. If the resolution is low, you will get a small picture and when you try to enlarge the photo the pixels become mixed up. For example, if you ever went on a computer and enlarged a low-resolution picture you know that the pictures was taken on a low-resolution camera because the picture becomes blurred. If you would have employed a medium or high-resolution camera the picture would be larger than a wallet size picture, or 4 by 6 inch picture and you wouldn't need to enlarge the photo. Yet, you could edit, crop or do whatever you like in your photo-editing gallery with ease. PPI is the number of pixels per inches that must match the resolution. If you have more pixels per inch at what time you are snapping a picture, the resolution will produce a brighter, colorful picture. For example, if the pixels estimate a resolution of 300 x 150 x 75, you will have a quality picture in front of you to edit. On the other hand, if the pixels are low and the resolution is low, your pictures if enlarged will appear in the photos. That is the pixels will become evident. Thus, if you are printing your pictures onto paper from a printer, the most pixels that will give you a quality picture is around 300 pixels per inch. You will also need to set your resolutions in your printer to achieve high quality photos. Resolutions and pixels go higher in number, however if you want the best possible pictures, stick with this number of pixels per inch, otherwise prepare to undergo problems. Otherwise, the higher the pixel the less likely you will get quality. If you are putting pictures on a Web Page, bear in mind that the pixels must be low resolution, because anything higher will jam the visitors' progress. In other words, the higher the pixel the more time it will take to upload or download the web page. What a pain! The standard web page images are around 72 or else 96 pixel per inch. Keep it low and your visitors are good to go! Note: You can change pixel size in a editing software programs, however the down sampling and up sampling process must work properly and respectively, otherwise you can damage the photos by deleting too much information or else by degrading your photos. Up sampling will add pixels while down sampling will delete pixels. The key is up sampling at a low percentage and down sampling at a low percentage also for the best effects. by Readabout's Digital Photography Training Team |
