After opening a picture in ‘Gallery’ tab the related scenes are shown next to it. The scene icon is shown if even one lamp in that picture is part of the scene.
With the scene icons you can control the scenes also from this view with same gestures as in ‘Scenes’ tab. Tap a scene to turn it on or off, pan a scene left or right to adjust the light level of the lamps in that scene. Colour temperature can be changed by panning up or down and if you want to change the colour of the lamps in that scene just hold the scene icon and colour selection will appear.
