Chapter 26 — Exercises

Developing is learned at the screen the way shooting is learned at the shutter — by doing it, comparing, and judging. Most of these exercises put you in front of a RAW file; a few train your histogram-reading and your eye for over-processing without any developer at all. There is no wrong software: your phone's RAW developer (Chapter 25), your camera maker's free desktop tool, or any non-destructive editor works identically for these. Difficulty is marked ⭐ (warm-up), ⭐⭐ (core), ⭐⭐⭐ (stretch). Do the starred and odd-numbered ones at minimum; model answers and critiques for those live in the book's Answers to Selected Exercises. Keep your developed files — one of them becomes your Portfolio Checkpoint.

A note before you start: if you do not yet have any RAW files, shoot a few first. A high-contrast scene (the red door in raking light, a backlit tree, a white building against blue sky) gives you the most to develop and the most to learn from.

Part A — Reading the histogram (Eye Training, no developer needed)

The histogram is the highest-leverage skill in this chapter and you can train it with no software beyond a photo viewer that shows one. Do these first; everything downstream depends on reading the graph fluently. The single distinction to drill until it is automatic: a slope reaching a wall usually means recoverable detail; a spike climbing a wall means clipped and gone.

Exercise 26.1 ⭐ — Name the regions. Open any photo on your phone or computer and bring up its histogram (most photo apps show one). In one sentence each, identify: where the shadows live, where the highlights live, and whether either edge has data piled against a wall. State whether the image is clipping anywhere.

Exercise 26.2 ⭐ — Predict the picture from the shape. You are shown three histogram shapes: (a) a tall hill bunched in the center touching neither wall, (b) most data shoved against the left wall with a small tail to the right, (c) two separate peaks, one near each wall, with a valley between. For each, describe in a sentence what kind of image would produce it (e.g. flat/ low-contrast, dark/underexposed, high-contrast). No developer required — this is pure reading.

Exercise 26.3 ⭐⭐ — Recoverable or gone? For each of these three described histograms, decide whether the highlights are safe, recoverable, or clipped and gone, and justify it: (a) a gentle slope that reaches the right wall and stops, (b) tones that fall well short of the right wall with a gap, (c) a hard vertical spike climbing the right wall. Say what you'd do at capture for the one that's gone.

Exercise 26.4 ⭐⭐ — Histogram before image. Shoot three exposures of one static high-contrast scene: the meter's "correct," one stop darker, one stop brighter. Before looking at the images, rank the three histograms by which best avoids clipping the important highlights while keeping the shadows off the left wall. Then look at the images and see whether your histogram ranking matches your eye's preference. Write what you learned.

Exercise 26.4b ⭐⭐⭐ — The blinkies hunt. Turn on your camera's highlight-clipping warning ("blinkies") and shoot five scenes you'd normally consider "bright": a snowy or sunlit white surface, a window in a room, a backlit subject, a white shirt in sun, a bright sky with clouds. For each, note whether the warning blinks on something you care about and what you'd do at capture to protect it (reduce exposure, reframe, wait for a cloud). The goal is to make the clipping warning a reflex, not an afterthought. Write which scene surprised you most.

Part B — The global develop pass (Shoot This / Develop This)

This is the heart of the chapter: the handful of global moves that do most of the work, run in order. Resist jumping between sliders — the order (white balance → exposure → recovery → curve) exists because each step is judged against the ones above it. If you only do four exercises in this whole set, make them 26.6, 26.7, 26.8, and the Portfolio Checkpoint (26.22).

Exercise 26.5 ⭐ — White balance, three ways. Take one RAW file and set its white balance three ways: (a) "as shot," (b) eyedropper on a neutral area, (c) deliberately too warm. Note how the same file's mood changes with color alone, and which version reads as "honest." Because it's a RAW, confirm for yourself that none of these costs any image quality.

Exercise 26.6 ⭐⭐ — Recover the wall, open the shadow. Develop a high-contrast RAW (the red door is ideal) using only four moves, in order: white balance, exposure, highlights down, shadows up. Stop there — no curve, no saturation, no sharpening. Compare to the flat original. Write what the highlight and shadow recovery revealed that the flat file hid (texture in a bright wall? grain in a dark recess? a detail you could not see before?). The point of stopping at four moves is to feel how much of the work the recovery alone does, before any contrast or polish — most beginners never realize how much is hiding in the extremes because they reach for contrast and saturation first.

Exercise 26.7 ⭐⭐ — The tone curve vs. the contrast slider. Develop one file two ways from the same starting point: version A adds contrast by dragging the single contrast slider to the right; version B adds the same apparent contrast with a gentle S-curve on the tone curve. Compare the shadow and highlight detail in each. Which preserved more, and why? State your verdict in one sentence.

Exercise 26.8 ⭐⭐⭐ — Place the tones (digital Zone System). Pick a scene with a clear range from a deep shadow to a bright highlight. Develop it so that: the deepest shadow reads as a true black (set the black point just to the edge of clipping), the brightest highlight holds detail just short of pure white, and a key midtone (skin, the red of the door, a grey wall) sits where your eye wants it. You are doing, with sliders and the curve, what Ansel Adams did in the darkroom (Chapter 8). Describe where you placed three specific tones and why.

Exercise 26.8b ⭐⭐ — Set a true black. Take any flat, low-contrast RAW and do only one thing: drag the blacks (or black-point) control down while watching the histogram, until the leftmost tones just touch the wall — establishing a genuine black anchor — then stop. Compare to the original. Notice how much "snap" a single true black gives an image that had none, and why a picture whose darkest tone is muddy grey looks washed out. One control, one big lesson.

Part C — Read the Frame (critique a Described Photograph)

Critiquing a develop trains the diagnostic eye you need to fix your own files — and to stop before you over-process them. Name what you see specifically (which tone, which slider went too far), not vaguely. These also double as alt-text practice (describing an image in structured words).

Exercise 26.9 ⭐⭐ — Diagnose the develop. Read this Described Photograph and name (1) what was done well, (2) one develop mistake, and (3) the specific fix:

"Backlit portrait, over-cooked"      [constructed teaching example]
  THE FRAME    A person against a bright window, hair rim-lit, face toward camera.
  THE DEVELOP  Shadows lifted to the maximum to brighten the face; contrast slider pushed hard right;
               saturation cranked; sharpening at full strength, judged at 100% zoom.
  THE RESULT   The face is bright but flat and slightly grey, with a faint blotchy, noisy texture in the
               cheeks. The window highlights have a hard white edge. Skin looks orange and plasticky, with
               bright halos along the jaw and hairline.

Exercise 26.10 ⭐⭐ — The flat negative, read correctly. Read this Described Photograph of a flat RAW and explain why each "problem" is actually fine — and what the develop should do about it:

"The red door, straight RAW"      [constructed teaching example]
  THE FRAME    A weathered red door in raking afternoon light, grey stone wall beside it.
  THE LOOK     Low contrast and dull. The red reads brick-brown. The lit wall is washed near-white. The
               overhang shadow is a featureless dark grey-brown. Slightly cool overall. The histogram is a
               soft hill in the middle, touching neither wall.

Exercise 26.11 ⭐⭐⭐ — Write a "developed" Described Photograph. Take a flat RAW you shot and develop it. Then write a full Described Photograph of the result using the six fields, with the develop choices made explicit in THE CHOICES field (white balance, recovery, curve). This trains you to articulate why you made each move — the skill that turns slider-poking into craft.

Part D — Non-destructive workflow (Settings Drill / Process)

These build the practice that makes developing safe and repeatable: never harming the original, treating edits as a portable recipe, and respecting the catalog. The habits here are what let you re-develop a keeper years later (as Adams re-printed Moonrise) and what stand between you and an accidental, permanent ruin of your only copy.

Exercise 26.12 ⭐ — Prove it's non-destructive. Develop a RAW heavily, then use your software's "reset" or "revert to original." Confirm the file returns exactly to how it started, with no quality loss. Write one sentence explaining where your edits were actually stored while they were applied.

Exercise 26.13 ⭐⭐ — Copy the recipe. Develop one RAW well, then copy its full set of adjustments and paste them onto a second, similar file from the same shoot. Note what transferred cleanly and what needed per-image tweaking (white balance and exposure usually need a nudge; the curve and corrections usually carry over). This is the seed of a preset (Chapter 25).

Exercise 26.14 ⭐⭐ — The broken-link drill. (Do this only if your software uses a catalog and you're comfortable.) With the software closed, move a photo's folder to a new location on your disk, then reopen the software. Observe the "missing file" indicator. Then reconnect it via the software's relocate/find function. Write the one-rule lesson about moving files. (If you'd rather not risk it, write out what would happen and why instead.)

Exercise 26.15 ⭐⭐⭐ — Two develops, one negative. From a single RAW, create two genuinely different finished images — say, a bright, airy, warm version and a moody, contrasty, cool version — using virtual copies / snapshots so both live as separate recipes over the same untouched original. Export both. This is the clearest possible demonstration that the negative is the score and the develop is the performance.

Exercise 26.15b ⭐⭐ — The "what did I do?" audit. Develop a file, then open its edit history or the list of adjustments your software recorded. Read your own recipe back: every slider you moved, in the order the software shows. Did you work roughly in the Figure 26.7 order, or did you bounce around? Write the three adjustments that did the most work on this file. This builds awareness that your edits are a recipe — readable, copyable, and reproducible — not magic.

Part E — The finishing layer (Develop This)

The polish — corrections, noise, sharpening — comes last and is where restraint matters most. The goal of this section is to train your eye to see the two cardinal sins (plastic-from-over-NR and halos-from-over- sharpening) at normal viewing size, so you never ship them.

Exercise 26.16 ⭐ — Lens profile on/off. Find a file shot with a wide lens (a phone ultra-wide is perfect) showing some corner darkening or bowed lines. Toggle the lens-correction profile on and off. Describe what changed (distortion straightening, vignette evening out, color fringing vanishing along high-contrast edges). Decide whether the correction improved the image — usually it does, but note that occasionally you might want a vignette or a touch of bowing for effect, in which case you'd correct selectively. Knowing what the profile fixes lets you choose, rather than accept the default blindly.

Exercise 26.17 ⭐⭐ — The noise/detail trade-off. Take a file shot at high ISO or with heavily lifted shadows. At 100% view, increase luminance noise reduction in steps until the grain is gone — then keep going until the texture turns plastic. Find the point just before the damage. Write down roughly where "clean" became "mushy" and what you lost.

Exercise 26.18 ⭐⭐ — See over-sharpening. Export one developed file three ways: barely sharpened, tastefully sharpened, and obviously over-sharpened (visible edge halos). View all three at normal size, not zoomed. Caption each with whether it looks soft, right, or crunchy. Keep the tasteful one. The goal is to train your eye to spot halos instantly.

Exercise 26.19 ⭐⭐⭐ — Wrong order on purpose. Develop one file in the correct order (Figure 26.7) and a copy in a deliberately wrong order — sharpen first, then noise-reduce, then set white balance and tones last. Compare. Describe specifically how the wrong order degraded the result (sharpened noise, shifting colors, redone work). This proves the order matters by showing what breaks without it.

Part E2 — Develop Drills (write the develop plan)

Given a described file and goal, write the develop plan — the ordered list of moves and roughly how far — the way Part C of other chapters has you write exposures. No software needed; this trains you to think the develop through before touching a slider.

Exercise 26.19a ⭐⭐ — Drill: the blown-window interior. A RAW of a room interior shot toward a bright window: the window and the wall around it read near-white (leaning toward the right wall, no hard spike); the room corners are very dark but not clipped; color is slightly warm from a household bulb. Goal: a balanced, honest image showing both the window view and the room. Write the ordered develop plan (which controls, which direction, roughly how far), and name the one move that does the most work here.

Exercise 26.19b ⭐⭐⭐ — Drill: the high-key portrait. A RAW of a portrait against a bright white background, intended to stay light and airy (high-key). The histogram has most data on the right without a hard spike; the skin is well-exposed. Goal: keep it bright and clean without clipping the skin or going flat. Write the develop plan, and explain why you would not "center" this histogram or add a heavy S-curve. (Connects high-key seeing, Chapter 8, to develop.)

Exercise 26.19c ⭐⭐ — Drill: the noisy night shadow. A RAW shot at high ISO at night (Chapter 21): the subject is fine, but you lifted the shadows and now the dark areas show grain and a few colored specks. Goal: clean, usable shadows that still hold texture. Write the finishing plan — what you'd do, in what order, and what you'd be careful not to overdo.

Part F — The repeatable order (Process / Portfolio)

The payoff section: turning everything above into a single fast, calm sequence you run on every file. Keep Figure 26.7 open beside you for these. The aim is muscle memory — develop enough files in order that the order disappears and only judgment remains.

Exercise 26.20 ⭐⭐ — Develop by the numbers. Take a RAW you care about and develop it strictly top-to-bottom through Figure 26.7, narrating each step aloud, resisting the urge to jump around. Time yourself. Then develop a second file the same way. Note whether the order felt slower or faster than your usual approach by the second file.

Exercise 26.21 ⭐⭐ — Ordered vs. freestyle. Develop one file twice: once strictly by the Figure 26.7 order, once freely jumping between sliders as the mood strikes. Compare the two results and how each process felt. Most people find the ordered pass calmer and more balanced; report whether that held for you.

Exercise 26.22 ⭐⭐⭐ — Re-process a Portfolio keeper (the Checkpoint). This is your Portfolio Checkpoint as a graded exercise. Choose a Portfolio image you shot in RAW and re-develop it fully via Figure 26.7, non-destructively. Export a finished full-resolution file and replace the old JPEG in your Portfolio list. Write the two required sentences: what the develop revealed that the flat file hid, and what you deliberately chose not to push. Keep the flat RAW, the old JPEG, and the new develop side by side.

Part G — Interleaved (mixing prior chapters)

Exercise 26.23 ⭐⭐ — Expose, then develop. Connect Chapters 3 and 26. Shoot one scene at three exposures using the histogram to expose to the right (brightest frame without clipping). Develop that brightest frame — pulling it back down — and compare its shadow noise to the develop of a darker frame brightened up. Confirm with your own eyes that the expose-to-the-right frame has cleaner shadows. (Revisits the exposure triangle, Chapter 3.)

Exercise 26.24 ⭐⭐ — Color seeing into color developing. Connect Chapters 7 and 26. Develop the red door so the red sits in genuine color contrast against the grey wall (Chapter 7). Adjust white balance and vibrance so the red reads as true vermilion, not brick-brown or neon. Write how your color-theory knowledge guided the develop.

Exercise 26.25 ⭐⭐⭐ — The Zone System, then and now. Connect Chapters 8 and 26. Take a single scene with a wide tonal range and previsualize (Chapter 8) where you want three key tones to fall. Capture exposing for the highlights, then develop to place those three tones exactly — deep shadow as true black, key midtone where you saw it, highlight just short of white. Write a short paragraph relating what you did to Ansel Adams' darkroom craft. (Revisits the Zone System, Chapter 8.)

Exercise 26.26 ⭐⭐ — Mobile to desktop, same thinking. Connect Chapters 25 and 26. Develop the same RAW once on your phone (Chapter 25) and once on a desktop developer following Figure 26.7. Compare the results and the experience. Confirm the thinking — histogram, recovery, order — was identical; only the interface changed. Note which you'd reach for and why.

Exercise 26.26b ⭐⭐⭐ — Re-develop an old keeper with new eyes. Connect this chapter to your own growth (and to Case Study 26.1's "one negative, many prints"). Find a RAW you developed months ago and were happy with. Without looking at the old develop, develop the original again from scratch by Figure 26.7. Then compare the two. What does your present judgment do differently? This is the single best argument for shooting RAW and keeping originals: the photographer you are now can outperform the one who first developed it — but only because the negative was untouched and waiting.

Exercise 26.26c ⭐⭐ — Zone System bridge (Ch.8). Take a single tonal-range scene and, before developing, sketch (in words) where you want three tones to land: which thing should be near-black, which is your mid-grey anchor, which should be the brightest detail short of white. Then develop to put them there — blacks slider for the near-black, exposure/curve for the mid-grey, highlights/whites for the high tone. Write a sentence mapping each develop control to the "zone" it placed. This makes the Chapter 8 abstraction concrete in your own developer.

Part H — Reflection (Eye Training & synthesis)

Exercise 26.27a ⭐ — The flat-negative reframe. Write three sentences, in your own words, explaining to a beginner why a RAW "looking flat" is good news. Use the negative/print (or score/performance) analogy. If you can teach it simply, you understand it — and you will never again be disappointed by an unprocessed file.

Exercise 26.27b ⭐⭐ — Your develop confessions. Honestly list the develop over-reaches you catch yourself doing (most people: over-saturating, over-lifting shadows, over-sharpening, skipping white balance). For each, write the tell that would warn you (a histogram spike, a garish color, a halo) and the one-line fix. Pin this list next to your screen for your next five edits.

Stretch challenge

Exercise 26.27 ⭐⭐⭐ — Develop ten, find your defaults. Develop ten different RAW files from the same camera, each via Figure 26.7. Pay attention to which moves you make every time (a touch of S-curve? a default sharpening? always pulling highlights?). Those repeated moves are the beginning of your personal baseline develop — a starting preset. Write down the five adjustments you found yourself making on nearly every file. This is how a develop style (Chapter 39) is born: not from one file, but from noticing your own repeated judgment across many.

Exercise 26.28 ⭐⭐⭐ — The one-week develop discipline. For seven days, develop one keeper per day, each strictly by the Figure 26.7 order, each non-destructively, each replacing nothing (keep the flat RAW beside it). At week's end, lay the seven developed images out together with their seven flat originals. You will see two things at once: how much picture was hiding in each flat file, and how much faster and calmer your seventh develop was than your first. That visible improvement, in your own hands, across seven days, is the chapter's whole argument — the develop is a learnable craft, and the order is what makes it stick.

Model answers and critiques for the starred and odd-numbered exercises appear in the book's "Answers to Selected Exercises." Develop the file yourself before reading them — at the screen as at the shutter, the attempt is the lesson.
