Plan the relationship between idea and image

Argument Visual evidence Position in the text Caption
A useful image has a function you can express in a single sentence.

What it is

Before selecting screenshots, list what the article needs to explain. For each claim, indicate what visual evidence would help the reader. The visual plan can include the idea, a candidate timestamp, essential detail, and the predicted position.

Why learn

Capturing first and writing later often leads to a collection of loosely connected images. Starting from the didactic function prevents inserting a dashboard just because it’s colorful. Sometimes an author-made table or diagram explains better.

Key concepts

Argument what the text claims.
Evidence what the image shows.
Position where it helps.
Caption explicit link to the idea.
COMMENTED EXAMPLE · 3.2.1
Idea: the review found two mistakes.
Visual: screen showing the test results.
Detail: two failing cases and the summary.
Position: after explaining the evaluation criteria.

✓ Do it like this

Write the function before choosing the frame.

✗ Avoid this mistake

Use the same frame for different claims without an explanation.

Practice before revealing

Which visual explains the difference between a rule and a judgment best?

View commented response

A side-by-side comparison with exact calculation and editorial choice. A decorative photo of a computer does not show that difference.

2

Choose stable, complete frames

Transition Stable frame Complete detail Approved capture
The best moment is when the information is complete, not a second chosen in advance.

What it is

A good screenshot must make sense as a static image. Check whether a transition has finished, whether the cursor doesn’t cover the data, and whether important labels are present. Go back a few moments in the source when needed to recover context.

Why learn

The article reader didn’t see the seconds before. A box without a title or a number without a unit requires guessing. This is one of the problems shown in the video comparison: screenshots that belong to the source but don’t work when used in isolation.

Key concepts

Stability animation completed.
Context label and unit are present.
Focus visible detail.
Source recoverable timestamp.
COMMENTED EXAMPLE · 3.2.2
Fail: half the table is still off-screen.
Fail: score is visible, but without the metric name.
Pass: result + label + sufficient context.

From concept to action

  1. Transition: identify the initial condition.
  2. Stable frame: apply the described decision.
  3. Complete detail: check the effect in the example.
  4. Approved capture: record the output evidence.

✓ Do it like this

Compare at least two frames when the moment is ambiguous.

✗ Avoid this mistake

Accept a crop only because it was taken from the correct video.

Practice before revealing

Does an isolated “94” number explain a quality improvement?

View commented response

No. You need to show or explain the metric, the scale, and the relationship with the previous evaluation. The number alone could mean anything.

3

Crop to explain without distorting

Entire image Relevant area Preserved context Final reading
The detail grows, but the labels that give meaning remain within the frame.

What it is

A good crop increases relevant information and preserves context. A highlight can guide the eye, but it shouldn’t hide values that would change interpretation. For sensitive material, use opaque redaction when removal is necessary and authorized.

Why learn

Excessive zoom removes titles; insufficient zoom makes the text unreadable. The choice must be verified at the actual reading size. Never declare that privacy is “resolved” just because a blur effect was applied.

Key concepts

Crop remove distraction.
Context preserve meaning.
Highlight guide the viewer’s attention.
Review check exposure and readability.
COMMENTED EXAMPLE · 3.2.3
Crop checklist
[ ] The central data is readable.
[ ] The title or caption explains the metric.
[ ] No essential label was cut off.
[ ] Sensitive fields do not appear in the final output.

✓ Do it like this

Inspect the final file after exporting the image.

✗ Avoid this mistake

Mistaking a visual highlight for proof that the content is correct.

Practice before revealing

If removing the header makes the number ambiguous, what’s the solution?

View commented response

Enlarge the crop or add a faithful and sufficient caption. If the caption has to invent context that the source does not provide, the image is not usable.

4

Place images next to the explanation

Claim Image corresponding Interpretation Next idea
The didactic unit is the text + image set, not the isolated image.

What it is

The sequence of text and image builds understanding. The reader should find the image near the statement it supports. Four screenshots grouped at the end can indicate that the insertion failed or that the review didn’t check the final order.

Why learn

The video shows this problem by comparing outputs: having the images in the document isn’t enough. Verification must go through the assembled article, including the space between blocks and the link to the paragraphs.

Key concepts

Proximity less visual searching.
Order follows the reasoning.
Caption explains the relationship.
Pace alternates explanation and evidence.
COMMENTED EXAMPLE · 3.2.4
Good: explain the three filters → show the three filters.
Bad: explain the report → show the initial screen.
Bad: finish the article with captures without a caption.

✓ Do it like this

Read the final sequence like someone who hasn’t seen the source.

✗ Avoid this mistake

Approve by counting the inserted files.

Practice before revealing

A relevant image appears three sections after the paragraph. What should you review?

View commented response

Reposition the image near the paragraph or reorganize the textual sequence. The correction is layout-related; it does not require regenerating the entire article.

5

Inspect desktop, mobile, and interface states

Desktop Mobile Keyboard + themes Defect record
Vary the reading condition; keep the same task to compare.

What it is

A page needs to be viewed rendered to confirm geometry, contrast, and readability. Open different widths, test keyboard navigation, and check expanded states, themes, and panels. Screenshots are evidence of specific states, not of all possibilities.

Why learn

Reading the code doesn’t necessarily reveal cut-off text, focus hidden by the menu, or a button covered by another element. Review must link visual observations to concrete actions and preserve content while correcting the layout.

Key concepts

Viewport reading area size.
Overflow the content overflows the container.
Focus visible keyboard position.
State open, closed, theme, and progress.
COMMENTED EXAMPLE · 3.2.5
Step 1: open the page and the first section.
Step 2: reduce to mobile width.
Step 3: use Tab and open the panel.
Step 4: check text, focus, and scrolling.

From concept to action

  1. Desktop: identify the initial condition.
  2. Mobile: apply the decision described.
  3. Keyboard + themes: check the effect in the example.
  4. Bug logging: record the output evidence.

✓ Do it like this

Record the width, page, and state of the observed defect.

✗ Avoid this mistake

Call one complete accessibility audit screenshot.

Practice before revealing

A table is wide on mobile. How do you preserve readability?

View commented response

Use a container with clearly identified horizontal scrolling, keeping the page within the screen. Don’t shrink the font until it becomes illegible, and don’t hide important columns.

6

Turn a visual defect into a testable rule

Observed defect Minimum rule New case Next review
A bad image becomes learning only when it changes the procedure and the test.

What it is

Useful visual feedback identifies the location, symptom, and effect. “The second image cut off the title and became incomprehensible” is more actionable than “the images looked bad”. The new rule should address the cause and feed into the next review.

Why learn

If you only fix the final file, the process may repeat the same error in the next run. Update the selection instruction, add a test case, and check whether the change also works in a different video.

Key concepts

Observationconcrete defect.
Impactharm to the reader.
Rulegeneralizable prevention.
Testcase that detects recurrence.
COMMENTED EXAMPLE · 3.2.6
Defect: frame captured during a transition.
Rule: choose complete, stable visual states.
Test: video with long animation in the main explanation.
Acceptance: no frame depends on content that’s still hidden.

✓ Do it like this

Preserve good examples as a counter-proof of correctness.

✗ Avoid this mistake

Prohibit all motion frames because of one case.

Practice before revealing

Write feedback for four standalone images at the end.

View commented response

“The last four captures have no clear link to the paragraphs. Link each one to a statement, reposition it, and check the rendered sequence. Remove the ones that add no explanation.”

CHECK WITHOUT BLOCKING

Check your understanding

A frame was captured mid-animation and cut off the conclusion. What’s the smallest correction?
