Below I presented the 3 images with different ISO, which have been imported to the 4 image processing applications. Nevertheless, we must come through the awkward step at the early stage of our image processing, which is noise reduction. The RAW format gives us many more possibilities, than. There is a lot of information in the description of the difference between these 2 formats. ![]() The RAW ones aren’t denoised since they are like digital negatives and contain unprocessed (or minimally processed) data from a digital camera sensor. Basically, it is to be done by our camera, when saving the photo in. In my work, I would like to split between 3 images with different ISO sensitivities.įirstly I would like to pay attention to the initial denoise process. In this quite long article, I would like to tackle some noise reduction exercises with the utilization of a few open-source image processing tools. It is only one side, where the noise can play a positive role – this is the image sharpness. Unfortunately, noise can seriously deteriorate the quality of our image. ![]() It’s expressed by random speckles present on our image, which we can compare to the film grain for analog cameras. Noise is a ubiquitous feature for all images, which we take.
