Your computer should have a default image viewing program such as Photos for Windows or Preview on Mac. Just hold down the Command key and click on the image to bring up a menu, then select Open Image in New Tab. If youР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re operating Safari or a different browser on a Mac, youР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ll see the same type of option as above for opening an image in a new tab. Right-click on the image (on PC) and select Open Image in New Tab or similar.

If youР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ve found an image on a web page and want to view it on its own, you can usually open it in a new tab. Photographers can avoid the potential pitfalls of artifacts and posterization by saving photos in raw format. It may also cause the appearance of artifacts - aliasing on edges, blooming, or noise - which can severely affect image quality. Losing so much data may cause posterization - the loss of smoother transition between colors, making an image look blockier and abrupt.Images with clean edges and lines will lose some of their sharpness in the compression. Lossy compression may be a space-saver, but when dealing with very heavily compressed images, the quality will suffer.Post-processing is easier because white balance and saturation in JPEGs are set with the click of the shutter.Compared to lossless formats like GIFs, JPEGs are dramatically smaller in size. By intelligently discarding all the colors that the human eye canР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t pick out - called lossy compression - JPEGs keep their file size as small as possible. Their small file sizes allow for quick transfer and fast access for viewing online.JPEG files are arguably the most universally recognized image file format - compatible with most browsers, software, and apps.The trade-off between file size and image quality is where the JPEG debate heats up. Faster page loading times gives readers quicker access to content - plus, JPEGs donР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t take up too much storage space in the cloud. The smaller size means itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ll open faster on most browsers (including mobile) without sacrificing too much quality.Р В РІР‚СњР вЂ™Р’В®veryone from big-time publishers to bloggers benefit from using JPEG files on their website. While photographers tend to shoot in a raw format to ensure the most accurate capture of a picture possible, they often share the fruits of their labor online in JPEG form. ThatР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s what makes it the go-to file for photographers and web publishers alike. But this file format is still very much a mainstream favorite.Р В РІР‚СњР В РІР‚С› JPEG file can display 16.8 million colors while staying relatively small in size. Serious photographers still shy away from shooting in JPEGs because they want to keep all the image detail for post-processing or printing. The real value came in the JPEGР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s ability to store metadata - such as where and when a picture is taken, and even camera settings. Now, anyone could snap and store images in small enough files to fit on limited camera storage while displaying reasonably well. JPEG files came into their own with the advent of digital cameras and the World Wide Web. They came up with the concept of lossy compression, which removed visual data that the human eye couldn't see and averaged out color variation. ThatР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s when a group called the International Organization for Standardization (ISO) started working on ways to bring photo-realistic pictures to small screens around the world.Р В РІР‚СњР В РІР‚С›t the same time, the Joint Photographic Experts Group (JPEG) arrived on the scene and created its own standard to compress graphics files enough to work on the average PC. In 1986, monitor technology couldnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t produce on-screen graphics. This may make JPEGs better for everyday use, but it does mean sacrificing some of the original image quality. JPEG images group together the following filename extensions:Р В РІР‚СњР В РІР‚С› JPEG file supports up to 24-bit color and uses lossy compression to compress images for more convenient storage and sending. ItР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s the go-to file format for digital images - and it has been ever since photographers began snapping and storing images on digital cameras and other reprographic devices. JPEG stands for Joint Photographic Experts Group, an international organization that standardized the format during the late 1980s and early 1990s.
