In general, what does higher resolution in an image result from?

Higher resolution in an image is primarily the result of larger image sensors. A larger image sensor captures more light and details than a smaller one, leading to greater overall image quality and higher resolution. This allows for more pixels to be packed into the image, providing finer details and the ability to enlarge the image without losing clarity.

While other factors can influence image quality, such as light conditions and film speed, they do not directly relate to resolution like sensor size does. Consequently, larger image sensors are crucial for achieving higher resolution in digital photography and image capturing.
