ACE Color Correction & Adjustment 3

Question 1

Which Camera Raw slider controls the recovery of highlight detail that appears blown out to pure white?

Accepted Answer

Highlights

Answer

The Highlights slider in Camera Raw specifically recovers blown-out highlight detail by pulling luminance back from the upper tonal range.

Question 2

In Photoshop's Levels dialog, what is the purpose of the middle (gray) input slider?

Accepted Answer

Adjusts gamma/midpoint without clipping shadows or highlights

Answer

The middle Levels input slider adjusts gamma, redistributing midtones lighter or darker without clipping the endpoints.

Question 3

A Vibrance adjustment differs from Saturation because it:

Accepted Answer

Boosts less-saturated colors more and protects skin tones

Answer

Vibrance uses a smart algorithm that boosts muted colors proportionally more while protecting already-saturated hues and skin tones.

Question 4

What is the function of the 'Set Gray Point' eyedropper in the Levels or Curves dialog?

Accepted Answer

Neutralizes a color cast by making the sampled pixel pure neutral gray

Answer

Clicking with the gray-point eyedropper forces the sampled pixel to neutral gray, automatically removing any color cast.

Question 5

When working with a 16-bit image, which statement about tonal adjustments is most accurate?

Accepted Answer

More headroom for aggressive adjustments with less banding than 8-bit

Answer

16-bit images store 65,536 tonal values per channel, providing much more data to redistribute before posterization or banding occurs.
