Differences RAW & JPG

rawandjpgIf you own a more advanced camera then you can save your image in .RAW or .JPG format. Both do have their advantages and disadvantages.

 

 

 

 

 

Advantages of .raw (in comparison with jpg)

  • It contains more colour and brightness information. It can make differences between “dark dark dark dark” and “dark dark dark”. (JPG can distinguish between 256 levels of brightness, RAW between 4,096 – 16,384!)
  • All the information that sensor collects get into the .raw file. That gives the possibilty to edit the pictures in for example Lightroom much better than .jpg would do it.
  • Over-/ underexposed pictures can be better fixed, due to the amount of information saved in the brightness
  • White balance can be better adjusted
  • Noise reduction in Lightroom is very powerful in case you have a noisy picture (due to high ISO for example)
  • When you do some colour changes, the original file will not altered
  • A finer grading of colours and tones is possible (because more information is saved)

 

Disadvantages of .raw (in comparison with .jpg)

  • A .raw file needs mostly 20-30MB (by a 20MP picture), a .jpg 8-12MB (by a 20MP picture). So you need a hell of storage space to save them!
  • To save all your changes you need to export them as .jpg – that may take some time.
  • You cannot save so fast pictures in .raw than in .jpg, and the camera buffer gets faster full.
  • A .raw file is not all the time the same. A .raw file from Nikon, Samsung, Canon etc. is different, you need a decoder – or lightroom needs a decoder. Thats why with new cameras you need to update Lightroom.
  • You need an special editor, Lightroom is not for free (but expensive cameras do come with Lightroom), to view .raw – the standard windows explorer is not able to show .raw.
