I thought I might try to list all the basic human emotions and overtime answer the above question for each. However, deciding what the basic list of emotions is not straight forward. Depending on the theorist, there are 2 (happy/sad) to 11 basic human emotions with many, many more secondary and tertiary emotions.
Here are my thoughts on some elements the photographer might use to communicate the feeling of love:
- Get in close to the subject - creating a sense of intimacy. Distance tends toward loneliness, remoteness, etc.
- Compression - a telephoto vs a wide angle would better convey a sense of closeness vs. distance and separation.
- Warm colors vs cool - red might be very passionate where yellow might be more just warmth. Blue and green (ocean and grass) tend toward a feeling of calm and coolness.
- Soft focus or light - accentuate the warm glow one may feel when in love. Sharp detail may feel harsh.
- Lines - the type of lines to used to communicate love may depend on the particular aspect of love - say the excitement of new love (straight or diagonal) or the steadiness of long standing love (curved or horizontal lines)
Those are just my initial thoughts. What comes to mind compositionally when you think of "love"?
Blog image: I find it hard to think about communicating love outside of human interaction. This image of mother and child says it all to me. Examining this image, it makes use of all of the above items.: tight intimate shot, closeness - 200mm lens, warm sepia tones and soft light. As for lines, there are strong diagonal lines giving this image an uplifting feeling.
