RAW vs JPEG in Digital Photography

RAW vs JPEG is a question that is asked by every photographer. There are lots of reasons as to why RAW is superior to JPEG and vise versa. In basic terms JPEG is better due to its ease of use, and RAW is better for its extra options.  For new photographers Jpeg is easier to use because as soon as you take the picture it is processed within the camera. This means that once the images are uploaded to the computer you can then upload the images to Facebook. Where as with a RAW file you have to use a photo editing software such as Photoshop, Gimp or Paint.net to output the image to a usable format.  With Jpeg the settings your camera will set the color temperature and exposure, the camera will also process the image to add blacks, contrast, brightness, noise reduction and sharpening. The file will then be saved as a compressed Jpeg file. With Raw file instead of all the settings being defined at the time of capture, picture settings can be changed when the file is imported int

High Dynamic Range

High Dynamic Range other wise known as HDR, is a process that is applied to the image by the camera to compensate for colour loss, it gives an image a higher Dynamic range. Below you can see the effect in practise, The picture on the left shows how a camera usually captures an image and the image on the right shows a picture with HRD enabled.  The way HDR works is by combining three or more photos, one with normal exposure, one over exposed image and one under exposed image. Depending on the lighting of the area it can make an image look more blown out. HDR is very useful in low light areas. If the camera is unable to take a normally exposed image it will instead combine the images to create an effect of normal lighting. Before taking a photo with HDR enabled you have to remove any movement from the shot otherwise the image will come out blurry and you will get a ghosting effect. Some advanced forms of HDR are able to to combat the effect of ghosting. To take a good H
