Large / Small - Joint, yellow car
Transparent / Opaque - something with coloured film
Diagonal / rounded - shot in alley in town
Pointed / Blunt - macro of a needle with thread, blunt?
Liquid / Solid - ?? jelly?
Hard / Soft - lensbaby?
Smooth / rough - macro shots
Still / Moving - water
Straight / curved - tram lines
I've got some clear ideas for some of the combinations, but for some of the others I want to think about it for a while before committing to an idea.
