Multiple choice
Q1. When you tilt a camera up to fit a tall building, the building's vertical edges appear to lean toward each other. This effect is called: - A) Compression - B) Keystoning (converging verticals) - C) Bokeh - D) Vignetting

The single physical condition that keeps a building's verticals photographing as parallel is: - A) Using the smallest possible aperture - B) Using a tilt-shift lens (and only a tilt-shift lens) - C) Keeping the camera's sensor parallel to the building's face (camera level) - D) Shooting at golden hour
Q3. You're at the base of a ten-story building, can't step back, and don't own a tilt-shift lens. The best combination is to: - A) Tilt up, shoot loose with room at the top, and apply perspective correction afterward - B) Tilt up and accept the leaning building as "natural" - C) Use the longest lens you have - D) Wait for golden hour and the lean will go away
Q4. A tilt-shift lens corrects converging verticals primarily through its: - A) Tilt movement - B) Shift movement - C) Aperture ring - D) Image stabilization

True / False (justify your answer in one sentence)
Q15. A leaning, converging-verticals building is a defect of the camera and means you need a better camera. True / False?
Q16. A perfectly mathematically corrected building always looks more natural than one with a tiny residual lean. True / False?
Q17. Overcast, flat light is the ideal condition for exterior architecture the way it is for portraits. True / False?
Q18. You should choose your lens before deciding what the photograph is about. True / False?
Q19. Including the building's surroundings (context) is always better than cropping to pure façade. True / False?
Short answer
Q20. Name the three structural elements §18.1 says to look for in a building, and explain why the break in a repetition is usually a stronger subject than the repetition itself.
Q21. List, in order of preference, the four ways to deal with converging verticals.
Q22. Give two completely different strategies for getting both a room and its bright view properly exposed in an interior, and say when you'd choose each.
Q23. For an exterior, name the three things you mostly choose (rather than control) that govern the shot, and give one sentence on the ideal version of each.
What's wrong with this shot? (seeing questions)
Q24. Critique: "A photo of a glass office tower, shot from the sidewalk directly below at noon. The tower leans dramatically backwards, the two visible edges race toward each other near the top, the glass is a flat mirror of blank white sky, and the whole building looks like it's tipping over." Identify the two main problems and prescribe the fix for each.
Q25. Critique: "An interior of a sunlit living room at midday. The big window is a featureless white rectangle with no view. The room itself looks grey, flat, and lifeless. The warm lamp light and the cool window light clash into an unpleasant color, and the vertical edge of the bookcase tilts slightly. The camera was handheld." Diagnose all the problems and prescribe the full re-shoot.
Answer Key
Q1 — B. Keystoning is the wedge/falling-backwards effect; the leaning lines themselves are converging verticals. (Review §18.2.)
Q2 — C. Parallel verticals require the sensor (film plane) to be parallel to the wall — i.e., the camera level, not tilted up. The tilt-shift lens is one way to achieve it, not the condition itself. (§18.2.)
Q3 — A. With no room to step back and no tilt-shift lens, compose loose (leave sky at the top) and fix the convergence in software. (§18.2, the four fixes.)
Q4 — B. The shift movement raises the lens's view to include the building's top without tilting the camera; tilt is for focus-plane control. (§18.2–18.3.)
Q5 — B. A telephoto from far back compresses depth and flattens the grid into pure pattern, and distance keeps the camera near level. (§18.3, Figure 18.4.)
Q6 — C. A sunlit window is commonly 4–6 stops brighter than interior walls — beyond a single ordinary exposure's range. (§18.4.)
Q7 — B. Blue hour (or overcast) drops the outside light to within a stop or two of the room, so one exposure holds both — the strongest no-gear move. (§18.4, Figure 18.5.)
Q8 — B. Bracketing = several locked-down exposures at different brightnesses, blended into one image that holds detail everywhere. (§18.4.)
Q9 — B. The frames must align pixel-for-pixel to blend cleanly; camera movement between frames breaks the blend. (§18.4.)
Q10 — C. Harsh overhead noon sun flattens the façade and bleaches the sky — usually the worst exterior condition. (§18.5.)
Q11 — B. Available-light interior = only the light already present (daylight + existing lamps), no added flash. (§18.4.)
Q12 — B. Wide lenses up close exaggerate near–far depth and make lines rush toward vanishing points (and, note, worsen convergence). (§18.3.)
Q13 — B. Perspective correction stretches/crops the edges, costing a little resolution and softening the stretched area — so you compose loose. (§18.2.)
Q14 — B. The abstract eye shifts from "what it is" to "what it looks like" — pure line, shape, pattern, texture. (§18.6.)
Q15 — False. It's geometry, not a defect: tilting the camera makes the sensor non-parallel to the wall, so verticals must converge. Any camera does it; the fix is technique (level camera) or correction. (§18.2.)
Q16 — False. Our brains expect a slight convergence when we look up at something huge, so a perfectly corrected building can look unnaturally stretched/too tall; a tiny residual lean often reads as more natural. (§18.2, the over-correction mistake.)
Q17 — False. Flat overcast gives a featureless grey sky and flat façade light — usually unkind to exteriors, which want directional low sun and an interesting sky (the opposite of the portrait ideal). (§18.5.)
Q18 — False. Decide what the photo is about first, then let that idea pick the lens; leaving one lens on and letting it dictate the picture is the mistake. (§18.3.)
Q19 — False. Including context tells a story; excluding it makes a graphic study — both are valid. The real error is accidental context (a stray car/sign/wire) you didn't choose. (§18.5.)
Q20. Line, repetition, geometry. The break is stronger because the human eye loves a pattern broken — one different element in a field of sameness becomes a story, and the repetition is just the stage that sets it off (place the break on a power point). (§18.1, Figure 18.1.)
Q21. (1) Step back and shoot level (crop the foreground); (2) gain height to the building's mid-point and shoot level; (3) use a tilt-shift lens's shift movement; (4) correct in software (shoot loose, straighten after). (§18.2.)
Q22. Any two of: commit — expose for the room or the view and accept the other is sacrificed (when one element is clearly the subject); wait — shoot at blue hour/overcast so the light balances itself (the strongest move when you can choose your time); fill — turn on lamps / bounce gentle light to lift the room shadows and narrow the gap (when shadows are too deep); bracket & blend — several locked-down exposures combined (when the contrast is too wide and you can't wait). (§18.4.)
Q23. Time of day (golden hour to rake texture, or blue hour with lit windows — avoid flat noon); the sky (deep blue or dramatic clouds, not blank white); context (include to tell the story, exclude for a graphic study — but decide). (§18.5.)
Q24. Two problems: (1) Converging verticals / keystoning from tilting up at the base — fix by gaining height (shoot level from an upper floor or raised position) or stepping back and shooting level, with perspective correction as backup. (2) Bad light and a blank sky — the noon sun gives a flat, mirror-white glass and a washed-out sky; return at golden/blue hour for raking light, a deep sky, and warm reflections in the glass (a polarizer would help manage the glass and deepen the sky). (§18.2, §18.5.)
Q25. Problems and fixes: blown window — at midday the window-to-room gap is too wide; shoot at blue hour (or bracket and blend on a tripod) so both hold. Grey, flat room — expose deliberately for the room and read the histogram; add/turn on lamps and gentle bounced fill to lift the shadows. Color clash — set white balance deliberately for the mixed warm-lamp/cool-window light (shoot RAW to fix it precisely) rather than leaving it to auto. Tilted bookcase — level the camera (use the grid/level) and correct minor verticals in software. Handheld — put it on a tripod; the low-ISO, small-aperture interior exposure will be too slow to hand-hold, and a tripod is mandatory for bracketing anyway. (§18.4, §18.2.)
