Question 1

What does the brightness slider do?

Accepted Answer

Brightness adds or subtracts a flat value to every pixel. Positive values make the image lighter, negative values make it darker. A value of 0 keeps the original brightness.

Question 2

What does the contrast slider do?

Accepted Answer

Contrast adjusts the difference between light and dark areas. Increasing contrast makes lights lighter and darks darker. Decreasing it flattens the tonal range, creating a more muted look.

Question 3

Can I adjust brightness and contrast at the same time?

Accepted Answer

Yes. Both adjustments are applied in a single pass — brightness is applied first, then contrast. This lets you fine-tune the overall look with both controls simultaneously.
