Although some Raw converters offer useful features like automatic vignetting, distortion and colour-fringing correction, if the lens used is in their database. At this stage all you (well I) attempt to do is get the white balance and exposure right - pretty much ignoring any other options offered. Stage one is to use a RAW converter, such as Raw Therapee, Adobe Camera Raw, CaptureOne, etc. There are usually two stages to processing a RAW file. Top quality RAW processing software, like CaptureOne, can produce results that blow away anything you can get straight out of the Thanks, I used Windows Image Viewer only to know wich picture to edit :) Thanks for the explanation about the raw format and the different processes.īut now, how can I get a picture that actually looks good as the jpeg one or even better? Do you know any good guide for noise reduction in post-production of night thank for the answer (edit) Here watching in little and low quality, the raw seems not that bad.ġ366052 1366054 , The first is the RAW, the second is the Windows Photo viewer(both are low quality screenshots especially the second).ĭo you know how I can edit it correctly to look like the preview one? Because it looked like a good starting point to edit. The preview on camera and the Windows photo ones looks similar and pretty good to me. I know that raw pictures can look a bit bad sometimes and not like on the camera preview or the jpg, but those looks like two completely different pictures.The raw on RawTherapee is really bad, all noise, strage colors and a circle effect. Those were my first Milky Way pictures from a year ago and now I tried to edit them.įor editing at the moment I'm using GIIMP + RawTherapee. it's worth checking how your photos look in different apps on different devices, All JPEG applications compress files by averaging blocks of pixels. in order to view (and possibly edit) this raw data, you'll need a reliable raw data viewer/editor and a reliable screen in principle, a raw image contains only the light intensities and color information that reach your camera sensor I'm a complete amateur here but for me, your question breaks down into a couple of stages: Top quality RAW processing software, like CaptureOne, can produce results that blow away anything you can get straight out of the camera. But not if you just let lame default adjustments apply themselves. This is usually 12 or 14 bits and gives far more flexibility for enhancement than the 8 bit limit of a JPEG image file.īone up on the possibilities of high bit-depth image processing, and you'll see the advantage of shooting RAW. And to make use of the full bit-depth captured by the camera. The whole point is that a RAW file can be processed to remove those warts far more thoroughly than what can be done with the camera's limited CPU power. You need to understand that a RAW file is exactly what it says a file containing the raw data direct from the image sensor. If these enhancements are applied to the RAW file to same degree, then you'll end up with exactly the same looking image as what you see in Image viewer. JPEG images, which are what you see in Win Image Viewer (urrrgh!), are processed to include vignetting correction - the dark outer circle - and noise reduction.
