Photo comparison slide example with two captioned options

What is on the slide

Title

Riverbend Council, Two Park Designs, over two photo cards of equal size.

Option A, The Lawn

A photograph of an open grass reserve during a community event, with bunting, stalls and a crowd. Caption: $1.42M build, 380 at one event, 22 shade trees.

Option B, Garden Rooms

A photograph of a walled courtyard garden with potted planting, a timber bench and a paved floor. Caption: $1.86M build, 140 at one event, 61 trees and shrubs.

What the pairing shows

The same three measures appear in the same order under both photographs, so the comparison reads across rather than down.

When this is the right slide

Two equal photo cards with one measured caption each suit a comparison where the look of the option is most of the argument and the numbers only have to be present, not explained.

What to swap it for

Comparison: Before / After Split. Swap to the before and after split when the two things are the same place at two points in time and the story is a change rather than a choice between two designs.

What this slide shows

A centred title reads Riverbend Council, Two Park Designs, and two photo cards of identical size sit below it. The left card carries a photograph of an open grass reserve in use, with bunting strung between poles, a trestle table of cakes, a jumping castle and a crowd of families spread across the grass. Its caption reads Option A, The Lawn, then $1.42M build, 380 at one event, 22 shade trees. The right card carries a photograph of a walled courtyard garden: a clipped brick wall, two mature potted olives, a timber bench and a paved floor with planted pots along its edge. Its caption reads Option B, Garden Rooms, then $1.86M build, 140 at one event, 61 trees and shrubs. Each caption is a single line under a short bold label, which is what this layout gives, so the three measures are written as one compact list rather than as three separate lines of text.

When this is the right slide

Use it when the difference between two options is visible and a description would be slower than a photograph. Two site designs, two shopfront treatments, two packaging routes, two ward layouts: in each case the audience forms a view from the image in about a second and then wants two or three numbers to check it against. The layout is also useful in public consultation, where a written specification excludes people who do not read plans. It is the wrong slide when no honest photograph exists for one of the options, because a rendered image beside a real one is not a fair comparison and an audience will say so. It is equally wrong when the decision turns on figures rather than form, since a two column table holds far more numbers per square inch than a caption under a picture.

How to adapt it

First, fix the caption structure before writing either caption, then fill the same slots on both sides. Three measures in one order is enough, and any measure that only exists for one option belongs in the spoken commentary or the report. Second, choose photographs at the same time of day, the same season and roughly the same distance from the subject. A sunny afternoon on one side and an overcast morning on the other reads as a preference even when none was intended, and in a consultation setting that becomes a complaint. Third, keep each caption to one line. The card gives a single line of about eighty characters under the label, so $1.42M build, 380 at one event, 22 shade trees fits while a full sentence about staging and drainage does not. If the two options need a paragraph each, a stacked panel layout gives them room, and if the pair is the same place before and after a change, the before and after split is the layout that says so.
