Question 1

What does the 'Radius' slider in Unsharp Mask control?

Accepted Answer

The width of the halo created around sharpened edges

Answer

The Radius slider in Unsharp Mask determines how many pixels surrounding an edge are affected by the sharpening halo; lower values sharpen fine detail while higher values sharpen broad edges.

Question 2

Which technique involves blending multiple exposures to preserve detail in both bright windows and dark interiors in architectural photography?

Accepted Answer

Luminosity masking exposure blend

Answer

Luminosity masking allows precise blending of exposures based on brightness values, giving more natural results than automated HDR tonemapping for interior architectural shots.

Question 3

In black and white conversion, why does raising the Red channel slider typically lighten skin tones?

Accepted Answer

Human skin contains significant red pigment that maps to the red channel in RGB

Answer

Human skin contains red and orange pigments; in black and white conversion, boosting the red channel maps those warm tones to brighter grays, lightening skin.

Question 4

What is the 'Healing Brush' tool's key difference from the 'Clone Stamp' tool in Photoshop?

Accepted Answer

The Healing Brush blends texture, shading, and lighting from the source with the destination area

Answer

The Healing Brush matches the texture from the sampled source area but blends the luminosity and color of the destination, creating seamless repairs unlike the direct pixel copy of the Clone Stamp.

Question 5

When exporting a JPEG for social media, what does reducing the 'Quality' setting below 80 primarily risk?

Accepted Answer

Visible compression artifacts, especially in smooth gradients and edges

Answer

JPEG compression below quality 80 can introduce visible blocky artifacts, ringing around edges, and banding in smooth tonal gradients due to the lossy DCT compression algorithm.
