An exhibition label provides context, but it can also direct your attention before you have noticed your own response. Try spending a little time with an artwork first. Observe its scale, materials, colours and the way it occupies the room.
Choose one detail to follow. It might be a repeated shape, a sharp contrast or an area that appears unfinished. Describe what you can see before deciding what the work is supposed to mean.

Then read the label and return to the artwork. The new information may support your first impression, complicate it or point to something you missed. You do not have to replace your observation with the official description.
Keep a short note about one work after leaving the gallery. Remembering a particular detail often leads to a more useful reflection than trying to summarise the whole exhibition. Looking carefully is a skill you can practise without specialist vocabulary.
