Q1: Describe the main difference between brightness and contrast adjustments in image editing.
Ans:
Brightness adjustment primarily affects the overall lightness of the image, making it brighter or darker. Contrast adjustment, on the other hand, alters the difference between light and dark areas, making dark parts darker and light parts lighter.

Q2: Explain why it's important to avoid excessive saturation in image editing.
Ans:
Excessive saturation can make colors appear unnatural and oversaturated, resulting in a loss of image quality. It's important to strike a balance to ensure that colors look vivid but not overly saturated.

Q3: What does the sharpening tool do in image editing, and why should it be used cautiously?
Ans: 
The sharpening tool enhances the edges of objects in an image to make them appear crisper and clearer. However, it should be used cautiously because excessive sharpening can lead to unnatural-looking edges and increased image noise, detracting from the image's quality.

Q4: How can you reduce image noise in an image editing application, and what should you be cautious of when using this feature?
Ans:
Image noise can be reduced using tools like "Denoise" or "Reduce Noise." However, caution should be exercised when reducing noise to avoid over-processing, which can result in a loss of image detail and a blurred appearance.

Q5: Briefly explain the purpose of the "Auto Fix" tool in image editing applications.
Ans:
The "Auto Fix" tool automatically analyzes an image and makes adjustments to improve its overall appearance. It is a quick and convenient way to enhance images without manual adjustments, though fine-tuning may still be necessary for specific preferences.
