Composition & seeing11
Generada por IA
Concept
The underlying idea or story the image communicates.
Composition
How elements are arranged within the frame to guide the viewer's eye.
Leading Lines
Lines in the scene that guide the viewer's eye toward the subject.
Eye Flow
The natural path the viewer's eye follows through the image.
Negative Space
Empty areas in the frame that give the subject room to breathe.
Visual Weight
How much attention an element commands relative to others in the frame.
Subject Separation
How clearly the subject stands apart from its surroundings.
Clutter
Distracting elements that compete with the subject for attention.
Timing
Whether the image captures the right instant, technically or emotionally.
Emotion
The feeling a photograph transmits to a stranger: carried by expression, gesture, and light coinciding, not by a subject merely displaying it.
Posing
Managing what a body says to the camera: building a gesture line the subject can hold, so the frame just past the pose catches them having forgotten the lens.
Light, tone & exposure12
Generada por IA
Exposure
Whether the image's overall brightness serves the subject and mood.
Tonal Hierarchy
How brightness contrast directs the viewer's eye to the subject.
Dynamic Range
The span from darkest shadow detail to brightest highlight detail in the image.
Long Exposure
The shutter held open long enough that motion renders as accumulated form (silked water, cloud streaks, light trails, thinned crowds) anchored by still elements kept tack-sharp. In our scoring, a chosen duration reads as intent; an arbitrary smear or a shaken anchor surfaces as a sharpness flaw.
Midtones
The middle brightness range between shadows and highlights: where most image detail lives.
Highlight Recovery
Restoring detail in bright areas that appear washed out or pure white.
Dodge & Burn
Selectively brightening (dodge) or darkening (burn) areas to guide the viewer's eye.
Light quality
The size and direction of the light source: what the light does to the subject, not just whether there is enough of it.
Flash
A second light source with its own exposure: judged by the ratio it keeps with the ambient, and by whether the frame reads as lit or as flashed.
Histogram
The camera's bar chart of tonal population: how many pixels sit at each brightness from black to white.
Contrast
The global tonal spread of the delivered photograph, how far apart its darkest and brightest tones sit, read as a mood register, not a more-is-better axis.
Zone System
Ansel Adams' scale for naming tones, one stop apart from Zone 0 (solid black) through Zone V (the middle grey a light meter renders) to Zone X (paper white). When a critique asks for Zone III-IV separation, it wants the darkest shadows that still show texture (III) to hold a visible step apart from the fuller shadows above them (IV), so a dark area keeps its form instead of merging into one flat block.
Focus & sharpness6
Generada por IA
Focus
Whether focus landed on the intended subject.
Sharpness
Whether the correct plane is sharp but insufficiently crisp (camera shake, slow shutter, diffraction, lens softness, over-sharpening).
Capture Ceiling
The upper bound the file itself sets: no edit reaches it.
Depth of Field
How much of the scene is in focus from front to back.
Bokeh
The quality and character of out-of-focus areas, not just the amount of blur.
Noise vs. Grain
Noise is a flaw from high ISO; grain is an intentional aesthetic choice.
Color6
Generada por IA
Color
Whether the image's colors serve its mood and feel intentional.
White Balance
The color temperature setting that determines whether the image looks warm, cool, or neutral.
Color Cast
An unintended color tint across the image, where tones you know are neutral no longer read neutral.
Color Grading
Intentional color shifts applied in post-processing to set mood or style.
Color theory
The color wheel as a working tool: how hues behave by their distance apart, and the named relationships (complementary, analogous, triadic, split-complementary).
Saturation vs Vibrance
Two intensity controls that do different jobs: saturation multiplies every hue equally; a vibrance-class lift raises muted hues more than vivid ones and shelters the skin band.
Editing craft6
Generada por IA
Curation
Choosing which frames earn the slots: the judgment that only exists in the plural, where a frame competes against its neighbors instead of a standard.
Competition entry
Aiming a set at one contest: the rulebook that decides eligibility, the jury that decides what wins, and the condition they will see it in.
Edit Discipline
Whether post-processing enhances the image without becoming the image.
Masking
Applying edits to specific areas of the image rather than the whole frame.
Crop
Reshaping the delivered rectangle at the desk: its orientation, aspect ratio, and how close the frame stands to the subject.
Tone curve
The graph mapping every input brightness to an output brightness: deciding where in the tonal range contrast is spent.
