These images show before and after: Before radiometric terrain correction (RTC), Klamath Mountains in northern California appear stretched on one side and compressed on the other (left). RTC (right) moves pixels to unstretch the mountains and adjusts pixel values to subtract the effect of slopes on brightness.
