Design Atlas◑Photo editing
Curves, levels, histograms, dodge & burn — the names and principles behind editing tools. — 18 entries
Histogram (photo editing)히스토그램(사진 보정)
A bar graph of how many pixels sit at each brightness level, from black to white — read straight off the canvas pixels every time it updates.
Levels레벨(레벨 보정)
Remaps the tonal range using three points — black point, white point and gamma — to stretch contrast into the empty space at either end of the histogram.
Curves커브(톤 커브)
Maps input brightness to output brightness along a freeform curve — a far more precise version of levels.
White balance화이트 밸런스
Shifts a photo's overall color temperature warmer or cooler so a surface that should look white actually reads as white.
Exposure노출
Multiplies overall brightness up or down in stops (powers of two) — the most basic tone adjustment there is.
Contrast vs. clarity대비 vs 클래리티
Both get called "more contrast," but global contrast stretches the whole tone range while clarity only boosts local edge contrast in the midtones.
Vibrance vs. saturation바이브런스 vs 채도
Saturation boosts every color's purity by the same amount; vibrance boosts only the muted colors and leaves already-saturated ones alone.
Dodge and burn닷지 앤 번
Paint brightness or darkness onto specific parts of a photo — like a brush — to sculpt depth and guide the eye.
Unsharp mask언샵 마스크
Blurs a copy of the image on purpose, subtracts it from the original to isolate edges, then adds those edges back to make the photo look sharper.
Frequency separation주파수 분리
Splits a photo into a low-frequency layer (color and tone) and a high-frequency layer (fine texture), so each can be edited separately and recombined.
HDR tone mappingHDR 톤 매핑
Compresses a dynamic range wider than a screen can show down into the narrower range a display can actually reproduce.
Split toning스플릿 토닝
Tints shadows with one color and highlights with a different one, adding a two-tone mood to a photo.
Luminosity mask루미노시티 마스크
Uses a pixel's own brightness as a selection mask, so an edit applies only to the highlights, only to the shadows, or anywhere in between — automatically.
Blend if블렌드 이프
A rule for blending two layers by brightness range — show the layer below in this range, the layer above in that one.
Gaussian blur가우시안 블러
Replaces every pixel with a weighted average of its neighbors — the most fundamental blur algorithm there is.
Noise reduction노이즈 감소
Suppresses the random speckle (noise) that high ISO or dim shooting conditions add, while trying not to smear away real detail along with it.
Chromatic aberration fix색수차 보정
Realigns the R/G/B channels to remove the color fringing a lens creates by bending different wavelengths of light to slightly different points.
Crop and straighten크롭 앤 스트레이튼
Rotates a tilted horizon back level and trims away unneeded edges to recompose the frame — the most basic editing step there is.
