A finished-cup photo tells you three things reliably: symmetry, contrast, and placement. It cannot tell you why they went wrong. For that you need your notes from the pour, or a video.
Review the photo against those three things, write down the single clearest problem, and change one variable next time.
Check 1: Symmetry
Draw an imaginary line from the cup handle through the centre. Both halves of the design should mirror across it.
What asymmetry usually means:
- Design leans to one side: the spout was not aligned with the cup’s centre when you started pushing. See the symmetry fixes.
- Design stretched towards you: the pitcher drifted as you levelled the cup, or you cut through at an angle.
- One wing bigger than the other: the cup was tilted when the design formed.
A photo shows the result of all of these clearly. It does not show which one happened. That is what your note from the pour is for.
Check 2: Contrast
Contrast is how clearly the white design stands apart from the brown background.
- Sharp white edges, rich brown surround: milk texture and pour timing were both working.
- Washed-out, greyish design: too much milk mixed into the base, or the low pour started before the base was set.
- White blob with no internal detail: foam arrived as a lump. That is a texture problem, not a pouring problem. Check milk too thick or too thin.
A photo cannot prove the cause. Washed-out contrast could be texture, timing, or flow. Write down what you remember of the pour before deciding.
Check 3: Placement and size
Look at where the design sits and how much of the surface it fills.
- Design crowded against the far rim: the base was too big and the cup was nearly full when the pattern started.
- Tiny design floating in brown: same cause, earlier stage. Start the low pour sooner.
- Design off-centre towards the handle: the cup rotated as you poured, or you aimed at the handle instead of the centre.
What a photo can’t tell you
Photos hide everything that happened over time:
- Pour height. Whether you dropped low smoothly or hovered halfway shows in a video, not a still.
- Flow rate. A thin, hesitant stream and a confident one can produce similar photos.
- When the design started. The photo shows the result, not the fill level at the moment you began pushing.
- Milk texture in motion. Glossy paint versus dry foam is visible in the pitcher, rarely in the cup.
If you have looked at ten photos and still cannot name the cause, the next step is filming. The filming guide covers angles that show height, tilt, and flow without getting in the way.
A review habit that takes two minutes
After each session, for your best and worst pour:
- Name the clearest visible problem in one sentence.
- Write what you changed or intend to change next.
- Save both with the photo.
Saving the photo and note together is what makes the next session start where this one ended. LatteArtist stores a photo, a rating, and a note with each pour, so a week later you can compare attempts instead of relying on memory. The practice routine turns this into a repeatable session structure.
