The advantage of RAW-Files (1/2 )

Taking pictures in the RAW-factor isn’t just great for professional photographers also it can pays off for beginners and amateur photographers. You can use the pixel buffer of the camera raw information to get the maximum from your pictures.

Raw-files are like diamonds: the valuable raw information form the backbone of the images to develop an awesome result. Also some compact cameras use  raw files, for example the Canon PowerShot G7x a mega zoom camera.

Raw equal more image quality

The advantage of RAW-files compared to usual compacted jpeg image files is the big content of information. I try to explain it on some sample calculation: A RAW-file f. e. with a color depth of 12-Bit saved for any color (red, green or blue) each 4.096 brightness values (2^12). The result? almost 69 billion (68.719.476.736) possible color values! A jpeg just use 8 bit color depth and use only 16.777.216 color values. This isn’t the only advantage compared to jpeg-files – while a JPEG will lost quality conditioned by tonal value correction and white fader your RAW-file doesn’t already care about this steps.

Taking pictures in RAW

(Canon manual, I don’t use Nikon, sorry!)

It isn’t that hard to take photos in RAW. First of all you should turn on the P, M or B. I read that f. e. the Canon EOS 450D doesn’t take RAW-images files in the full automatic or other automatic modes. Well I know the Canon EOS 7D, Canon EOS 70D, Canon 7D Mk. II and Canon EOS 6D doesn’t care in which mode you are to take images in RAW-files. You should press the RAW/JPEG key to change it fast, or you go in the menu. Here in the menu you scroll down to quality, here you can change the settings. You have a range from RAW, MRAW or SRAW, you can additional use jpeg as backup or preview so you save the picture you took in two formats jpeg and raw. You can upload the jpeg also as well on image services or print the pictures direct from the camera this step isn’t possible with undeveloped raw-files. If you love continuous shootings you are maybe scared that the big raw files are slower as the smaller jpeg? Well honestly the raw is slower but that is depending to the high color depth and if you have a fast camera you notice it but not that much as f. e. if you are using a Canon EOS 70D or 7D and a high speed memory card  you will not notice that it is slower to take RAW-files as you would use a Canon EOS 100D or 700D, but don’t forget you can be more riskier with RAW-files because you can develop them better and you can make a higher detail zoom of the raw as with the jpeg.

Every manufactures use another RAW-factor 

If you want to develop your RAW-files on your computer it is necessary to have a RAW-converter because it is not possible for all the software on the market that can display jpeg also display RAW-files. Canon f. e. use the .CR” or the old RAW-format .CRW. Nikon for example saves the RAW in files ending with .NEF and the Pentax beginning with the K10D saves the RAW next to the own format in .DNG-files (digital negative picture) the .dng is an open RAW-format of Adobe.
