A different point of view
Use the camera as a comparison tool
Choose one photographic opportunity and decide what you want the image to show. Take a considered frame, then compare it with your direct view. Does the photograph emphasise the effect or hide something important? A screen gives you a bounded composition, so inspect what the frame leaves out as well as what it includes. Respect the instructions and other visitors throughout.
Exploring optical illusions in Gdańsk does not require an album of every room. After comparing an image, put the device away and look again without it. Ask a companion which detail they would have photographed instead. The difference can reveal contrasting interests, from visual patterns to playful posing. Neither choice needs to become a judgement about who understood the exhibition better.
