Using a tripod will stabilize your shots. Nodalview takes a burst of 11 pictures to guarantee the best quality for your photos – the result might not be optimal if you move during this burst. Nodalview does use re-alignment algorithms to try and prevent mis-aligned brackets but its always best to keep a shoot as steady as possible.
A tripod is also helpful to better adjust your shots and keep them shoot straight.
The use of a tripod is strongly recommended but not mandatory – you can test Nodalview on your smartphone without any accessories as long as you try to move as little as possible during the shoot and respect the level indicators inside the app.
