Day by day, more digital cameras have RAW format in their standard and it’s becoming more popular. For professional photographers that use digital cameras RAW is nothing new. I will try to explain what RAW format consists of in my own words so you could understand the general idea.
What is the difference between RAW and JPEG or TIFF format? To simplifie, when you are taking picture in JPEG or TIFF format, the camera automatically makes some adjustments as white-balance. The RAW format is… raw. It captures the the same image you see in your camera viewfinder converted to digital data. The rest is left for you to decide: you can reproduce the scene just as you’ve seen it.
The advantage is obvious: you get control over the image all over the time: from shutter movement till the final print. You make photo just as you like it. Camera’s processor works like a film: you can see no image until you enhance it in graphic program. Which one? The story begins here. There is no such thing as RAW standard; it means that each camera producer has its own RAW format. And that complicates the work a little. The positive thing about it is that they offer software that supports it. You can also use a third-party software.
With all the advantages as flexibility and huge image data, it’s not a perfect cure. Your skills are still valid. Even more. RAW cannot fix a bad exposure, you are still the responsable of making the possible as good as you can. Actually, I do not consider this as a disadvantage; more like a come-back to classical photography where you control the whole process. The only difference is that you have all your darkroom in your computer.
