What does a 'histogram' display in photo editing software?
Answer: A graph showing the distribution of tonal values (shadows to highlights) in an image
A histogram is a bar graph that shows how pixels in an image are distributed across the tonal range from pure black (left) to pure white (right).
In photo editing, what is 'dodging'?
Answer: Selectively lightening specific areas of an image
Dodging is a darkroom-derived technique for selectively lightening specific areas of an image by reducing exposure in those regions.
What is 'chromatic aberration' in a photographic image?
Answer: Color fringing where different wavelengths of light focus at different points along lens edges
Chromatic aberration is a lens flaw where different wavelengths of light don't converge at the same focal point, causing colored fringing (typically purple or green) along high-contrast edges.
What does 'non-destructive editing' mean in photo editing software like Lightroom?
Answer: Adjustments that don't permanently alter the original image file
Non-destructive editing stores edits as instructions separate from the original image file, so the original is never altered and adjustments can always be reversed.
What is 'noise' in digital photography?
Answer: Random variation in brightness or color information, appearing as grain-like artifacts
Digital noise is the random luminance or color variation in an image, similar to grain in film, caused primarily by high ISO settings or long exposures.
What does 'sharpening' do to an image in post-processing?
Answer: Enhances the perceived edge contrast to make details appear more defined
Sharpening increases the contrast along edges and fine detail, making an image appear crisper and more defined — it cannot recover truly out-of-focus areas.
