Usual suspects
- One-handed shooting — holding the phone and tapping the on-screen shutter with the same thumb.
- The press itself — level before you tap, nudged off by the tap.
- Posture — head or shoulders tilted while you look at the screen, so the scene looks straight to you.
- Wrong reference line — lining up with a sloped floor or roof line.
Which one is yours varies from person to person, so data beats guessing.
Measure first
Take about 20 shots in the same conditions and look at the direction and size of each tilt. An average pulled to one side is a habit; tilts scattered evenly both ways are just shake.
| Result | Meaning | Try |
|---|---|---|
| Average 0.3° or more to one side | A directional habit | Test the causes below |
| Average near 0°, wide scatter | Shake without direction | Two hands, timer |
| Average near 0°, tight scatter | You are already good | Tighten the tolerance |
Test one cause at a time
Change one thing, shoot another 20. If the average tilt drops, you found it.
| Change | Cause it reveals |
|---|---|
| Hold with two hands | One-handed grip |
| Shoot with auto shutter or timer | Force of the press |
| Straighten head and shoulders first | Posture |
| Line up with verticals (door frames) | Wrong reference line |
Seeing the habit in the app
The Android app "Level Camera" saves the tilt of every shot and sums it up in the Stats tab.
Habit check
Habit check says something like "Your shots lean 0.69° to the left on average." If the average lean is under 0.3°, it reports no consistent lean. Check the Tilt distribution chart below it too: is the cluster shifted away from 0°?
Compare with auto shutter
Turn on Auto shutter in Capture settings and shoot for a while. The Auto shutter payoff card in Stats then shows the success rate for manual and auto shots side by side. If auto is clearly higher, the press was the culprit.
FAQ
How is the grade calculated?
From the share of photos inside your tolerance: 90% or more is A+, 75% A, 60% B, 40% C, and below that D. A tighter tolerance lowers the grade for the same hands.
Do older photos count?
Only photos with a recorded angle. Photos without one are marked No record and left out of the accuracy stats.
