**Core Concept**
Digital radiography is a modern imaging technique that uses electronic sensors to capture and display X-ray images. This technology offers several advantages over traditional film-based radiography, primarily due to its ability to manipulate and enhance images digitally.

**Why the Correct Answer is Right**
The advantages of digital radiography include improved image quality, reduced radiation exposure, faster image acquisition, and enhanced image processing capabilities. Digital radiography allows for adjustable contrast and brightness, making it easier to diagnose subtle abnormalities. Additionally, digital images can be easily stored, retrieved, and transmitted, reducing the need for physical film storage.

**Why Each Wrong Option is Incorrect**
* **Option A:** Not a recognized benefit of digital radiography. While it may be a feature of some digital systems, it is not a primary advantage.
* **Option B:** Not a correct statement. Digital radiography does not inherently reduce the need for patient positioning or proper technique.
* **Option C:** Not a benefit of digital radiography. In fact, some digital systems may require more complex processing and calibration compared to traditional film-based systems.

**Clinical Pearl / High-Yield Fact**
Digital radiography allows for the use of advanced image processing algorithms, such as noise reduction and artifact correction, which can significantly improve image quality and diagnostic accuracy.

**Correct Answer: C. Reduced radiation exposure.
