Are the edited photos available in raw format?
Retouched photos are not in raw format.
The original meaning of RAW is unprocessed. It can be understood that the RAW image is the original data that the CMOS or CCD image sensor converts the captured light source signal into a digital signal. The RAW file is a record of the digital camera sensor. The raw information also records some metadata files generated by the camera shots.
Introduction to file formats
RAW files are information obtained directly from CCD or CMOS without processing. Photographers can maximize their artistic talents through post-processing.
RAW files do not have white balance settings but the real data has not been changed, which means that the author can adjust the color temperature and white balance arbitrarily without any loss of image quality.
Color linearization and filter row transformation are processed more quickly on computers with microprocessors, which allows the application of more complex algorithms that are not allowed on cameras.
The imaging chip is a linear device, which means that when one pixel receives twice as much light as another, it will produce twice the voltage. When the exposure is stopped, the brightness value is presented in its logarithm. , which means that an uncorrected photo will look darker and will need to be adjusted correctly via the tone curve.
