The optimum X-ray intensity varies depending on the sample to be radiographed. If you do not know the optimum X-ray tube voltage, radiate the sample with a lower X-ray tube voltage and gradually increase the voltage. When the histogram is displayed at about 80% of the total, the image will be better without saturation (white skipping).
If the contrast of the inspection area is low, you should conduct gamma correction, gamma curve adjustment, or histogram flattening.
