Final answer:
Moving the curve of the look-up table to the left in a digital image affects the pixel values by introducing a negative shift, making the darker areas even darker and bright areas more washed out.
Step-by-step explanation:
Moving the curve of the look-up table to the left affects the digital image by introducing a negative shift in the pixel values. This means that the darker areas of the image will become even darker, while the brighter areas may become more washed out.
For example, if there is a value of 100 in the original image, shifting the curve to the left by 50 units will result in that value becoming 50. Similarly, a value of 200 will become 150.
Overall, this adjustment can enhance the contrast in the image, making the darker regions more prominent.
