| Question 1 |
If the histogram of an image is clustered towards origin on X-axis of a histogram plot then it indicates that the image is ______.
| Dark | |
| Good contrast | |
| Bright | |
| Very low contrast |
Question 1 Explanation:
→ If the histogram of an image is clustered towards origin on X-axis of a histogram plot then
it indicates that the image is dark.
→ An image histogram is a type of histogram that acts as a graphical representation of the tonal distribution in a digital image. It plots the number of pixels for each tonal value. By looking at the histogram for a specific image a viewer will be able to judge the entire tonal distribution at a glance.
→ The histogram for a very dark image will have the majority of its data points on the left side and center of the graph. Conversely, the histogram for a very bright image with few dark areas and/or shadows will have most of its data points on the right side and center of the graph.
it indicates that the image is dark.
