Photography Digital Post-Processing Workflow 2 — Questions and Answers
Question 1: Which color profile is best for images intended for web and screen display?
- Adobe RGB (1998)
- ProPhoto RGB
- sRGB (Correct answer)
- CMYK
Correct answer: sRGB
sRGB is the standard color space for web and screen display because it matches most monitors and browsers.
Question 2: In Lightroom, what does the 'Clarity' slider primarily affect?
- Global contrast across the entire tonal range
- Mid-tone contrast and local edge definition (Correct answer)
- Shadow recovery in underexposed areas
- Color saturation in mid-tones
Correct answer: Mid-tone contrast and local edge definition
Clarity increases mid-tone contrast and edge definition, adding perceived sharpness and texture without affecting highlights or shadows as strongly.
Question 3: What is the purpose of using a 'luminosity mask' in post-processing?
- To remove chromatic aberration from lens edges
- To make selections based on the brightness values in an image (Correct answer)
- To convert a color image to black and white
- To reduce digital noise in shadow areas
Correct answer: To make selections based on the brightness values in an image
Luminosity masks create selections based on pixel brightness, allowing targeted adjustments to specific tonal ranges like highlights or shadows.
Question 4: When dodging and burning in Photoshop, setting the Range to 'Midtones' will primarily affect which tonal area?
- Only the brightest highlights
- Only the darkest shadows
- The middle gray tones of the image (Correct answer)
- All tones equally
Correct answer: The middle gray tones of the image
Setting the range to Midtones concentrates the dodge or burn effect on middle gray values, leaving extreme highlights and shadows less affected.
Question 5: What does the term 'clipping' mean in the context of a histogram?
- Cropping part of the image frame
- Tonal values pushed beyond recoverable pure white or pure black (Correct answer)
- Removing color fringing from lens edges
- Reducing the file size by compressing data
Correct answer: Tonal values pushed beyond recoverable pure white or pure black
Clipping occurs when tonal values exceed the displayable range, resulting in pure white (highlight clipping) or pure black (shadow clipping) with no recoverable detail.
Question 6: Which blending mode in Photoshop is most commonly used when sharpening with the High Pass filter?
- Multiply
- Screen
- Overlay (Correct answer)
- Luminosity
Correct answer: Overlay
Overlay blending mode with a High Pass filter enhances edges and contrast, effectively sharpening the image while retaining overall tonal balance.
Question 7: In a RAW workflow, what is the main advantage of adjusting white balance before converting to TIFF or JPEG?
- White balance can only be changed in RAW format
- RAW adjustments are non-destructive and preserve full data range (Correct answer)
- TIFF files do not support white balance metadata
- JPEG files compress better after white balance is set
Correct answer: RAW adjustments are non-destructive and preserve full data range
Adjusting white balance in a RAW converter is non-destructive and works on the full bit-depth data, giving more accurate and flexible color correction than editing a processed file.
