Validity check
- Same hoof + same view.
- Similar angle and distance.
- Hoof is in focus (sharp edges).
- No extreme lighting differences (silhouette vs washout).
Not medical advice.
This guide is about documentation and visual comparison habits, not diagnosis or prediction.
Core rule
Compare like-with-like.
Most comparison confusion comes from comparing different things.
Match these for a clean comparison:
- Same view (dorsal with dorsal, lateral with lateral, solar with solar).
- Same hoof (LF with LF, not LF with RF).
- Similar framing (hoof fills the frame similarly).
- Similar distance.
- Similar angle.
- Similar lighting (close enough is fine - avoid extremes).
Start small
Start with two dates, then expand.
- Date A: the older set.
- Date B: the newer set.
- Compare: the same hoof + the same view across both dates.
Once A vs B is clean, add more dates to build the trend.
Checklist
What to compare (a non-diagnostic checklist).
Focus on what the camera captured, not what it might mean.
Framing consistency
- One photo taken from noticeably higher or lower?
- One photo tilted or pitched forward?
- One closer, making edges look larger?
If yes, treat apparent differences cautiously and recapture.
Practical notes
Record factual context that affects the timeline:
- Post-trim.
- New shoes.
- Footing change.
- Travel week.
Notes should explain why the record looks different, not what it means.
If the validity check fails, fix the comparison first (see when comparisons are not valid).
Workflow
A simple comparison workflow.
Step 1: Pick your comparison set
- One hoof (LF/RF/LH/RH).
- One view (dorsal/solar/lateral).
- Two dates (A and B).
Step 2: Place them side-by-side
Use an album, files, or Eqvira session view. The key is simultaneous viewing, not memory.
Step 3: Do one view at a time
Compare LF dorsal A vs B, then LF lateral A vs B, then LF solar A vs B.
Step 4: Write one factual sentence (optional)
Example: "Compared 2026-01-05 to 2026-02-05; post-trim between sessions."
Validity
What valid comparison looks like.
- Same view.
- Similar distance.
- Similar framing.
- Similar light.
- Crisp focus.
If the comparison feels dramatic, it is often the camera, not the hoof.
Troubleshoot
When comparisons are not valid.
Angle drift (most common)
Signs: one lateral shot is level, the other is top-down, or one dorsal shot is front-on and the other is off to the side.
Fix: recapture using your stance rule: dorsal front-on, lateral hoof-level, solar straight on.
Distance drift
Signs: one photo is tight and the other is wide, making proportions look different.
Fix: pick a consistent distance cue (same step back, same mat, same zoom).
Lighting extremes
Signs: one photo is backlit or blown out, the other is evenly lit.
Fix: move to open shade or reposition and retake.
Focus blur
Signs: edges look soft and details smear.
Fix: retake immediately and stabilize your phone.
Events
Comparing across trims or shoeing.
Recommended approach
- Compare before vs after only when views are consistent.
- Keep dates clear and label the event (post-trim, new shoes).
- Focus on the timeline, not conclusions.
No "before" set?
Start with the next clean baseline and build forward from there.
Structure
Structure makes comparisons easier.
- Sessions grouped by date.
- Each photo tied to hoof + view.
- A timeline view that keeps sessions in order.
That is the advantage of tools like Eqvira: the record stays intact, so comparison becomes routine instead of archaeology.
