In this blog I will compare an image shot in Raw, and processed by myself in a Raw processor and a JPEG that has been processed by my camera.
Every time you take an image in a digital camera a raw image is formed by the sensor. This Raw image is then processed by your camera, usually into a JPEG image. This JPEG is what comes out of your digital camera as the finished product.
Some digital cameras particularly Digital SLRs have the ability to save the Raw image so you, the Photographer, can process that image yourself in a Raw processor.
The advantage of this is that you can control the brightness, colour, colour temperature, contrast, saturation etc, etc, of that image and not accept what the camera spews out, and spews out is sometimes an appropriate word.
Raw processors are found in most photo editing computer programmes such as Photoshop, Photoshop Elements etc.
The disadvantage of Raw is that it is another time consuming step to get your finished image, and a Raw image is a bigger image by Mgb than a JPEG. You also usually keep your Raw image and have a processed image as well, so it takes up more hard drive space.
I will show you some of my images shot in both Raw and processed by me and a JPEG that is the end product of the cameras processing. My camera can save two images, one in Raw and one in JPEG from the same shot, so I am comparing the exact same image.
I usually save my processed image as a PNG image, but for this exercise I have both images in this blog as JPEGs.
I took these photos at dawn in Menangle.
You can of course edit your JPEG image that comes out of your camera to fix up problems with that camera processed image.
The Raw image supposed to be the best one to process because it contains all of the digital information from your camera. The camera processed JPEG has lost information in the in camera processing of the image so further processing by you is supposedly not as successful.
Fixing up JPEGs that come out of the camera may be a blog of it's own.
