INFO:

We take a look at how a digital camera works and the software and processing that is carried out to produce a photo from the original sensor data. We explore the differences between the sensors RAW data and a JPEG file. We use Raw Therapee to demosaic a picture and take a look at the Bayer pattern captured by the camera's sensor. We look at how the camera on senses light and is in fact monochrome/greyscale. We cover how the Bayer filter is used to allow the colour to also be captured. An 8 bit JPEG is very different to a 12-bit or 14-bit raw file. A JPEG can only hold 16.7 Million colours per pixel, whereas 12-bit raw is 68 Billion and a 14-bit raw file is 4.3 Trillion. #merciasolutions #jpeg #rawtherapee 0:00 90% of the data is discarded 0:34 JPEG vs Raw filesize compared 1:10 Monochrome / greyscale capture 1:30 Bayer Filter explained 2:10 Rawtherapee 2:50 RGB layers of sensor Bayer pattern 3:43 Camera considerations demosaicing process 4:40 The Camera is Lying, keep RAW files 5:39 8 Bit display 6:20 8-bit vs 10-bit vs 12-bit vs 14-bit 7:48 Future considerations
