RAW file format and program I use to work with it
Taking pictures in RAW file format has huge benefits. First of all you can better correct the exposure parameter. This is important because
a) if you shoot a picture and went home with the exposure not as you was expected (too light or too dark), you can easily correct 2-3 steps.
b) if you want to shoot a picture with low ISO and there is not enough light, the shutter would work to slow to get focused view, for your chosen aperture - try to shoot it -1 or -1,5 steps (manual correction) - you can always correct it at home, because it's RAW file format.
c) white balance is very important issue in photography. If you shoot in RAW file format you can more easily correct it. You can cold or warm the color, add tint - it's hundred of times easier than to correct it in JPG.
It's only one minus to shoot In RAW file format as I know - If you want to shoot series (many shoots in one time), it would be slower than in JPG because of the size of the file (raw is bigger). But if you camera is fast enough - shoot it in RAW and you'll definitely see the benefits.
The program I use to work with RAW is "darktable 9", It's totally free. But works only in ubuntu or linux.
I hope this article inspires someone to try to shoot in RAW file format and discover it's benefits. Good luck!
