SLR RAW format post-processing problems, great gods enter!

First, simply adjust the exposure contrast or something like dpp, which is slightly more complicated. If you want to play digital photography, lightroom and photoshop produced by adobe are good choices.

Second, the specific definition of raw will not be repeated. Please refer to/link by yourself? Url = ckni _ fmkzddtnhn2vxaeu20dhywqh8ncpccdmnijahw2v _ r4z _ _ tkfuhzq4upzba.raw records the original data in the camera. When you modify it, you don't mean lossless modification, but because a lot of data are recorded in raw, which can ensure that you have enough space in the later stage. If it is overexposed, the raw file cannot pull back the details, so in digital photography, underexposure is better than overexposure.

Third, files in raw format are actually just various data inside the camera. No matter what means you use (camera screen, computer, software) to watch raw, it is an image processed by some algorithm, so when you view raw with different software, sometimes you will find that the image is different.
