A JPEG picture is compressed to form it smaller which implies you’ll be able store more JPEG pictures on the SD card. After you open the picture using a program, the photo is decompressed once more permitting you to see it. there’s a drawback to JPEGs. The type of compression that JPEG files utilize is called “lossy compression” and, as you will have assembled from the title, in arrange to induce the estimate of the file down a few of the picture quality data is misplaced. Each camera producer has their possess identical of the Crude record, but they all work within the same way. A Raw file contains so much more image data and detail than a JPEG counting data approximately the measure of your camera sensor, your introduction settings, gap, focal point data, white adjust etc. A Raw file also contains a full-size JPEG photo that’s utilized to make that see for the screen on the back of your camera.
