In many cases, standard images can be processed in just a few hours, while HDR images may take significantly longer due to their complexity. This efficiency makes standard imagery a practical choice for time-sensitive projects, such as emergency response or initial site assessments.
How do HDR and standard aerial imagery compare?
HDR (High Dynamic Range) aerial imagery offers a broader range of light and color compared to standard aerial imagery. This difference can significantly impact the visual quality and detail captured in various lighting conditions.
Image quality differences
HDR imagery captures a wider spectrum of light, allowing for more detail in both shadows and highlights. This results in images that appear more vibrant and realistic, especially in challenging lighting scenarios such as sunsets or sunrises. In contrast, standard aerial imagery may lose detail in bright or dark areas, leading to flat or washed-out images.
When comparing the two, HDR images often exhibit richer colors and improved contrast, making them preferable for applications requiring high visual fidelity. However, standard imagery may suffice for basic mapping or documentation where color accuracy is less critical.
