Does a photo need to say something?

[ctg]

Honestly, we all have had great shots come out of some accidental action which shows that a picture is worth a thousand words . . . they tend to communicate something as an image. On the other hand we have all had our share of bad photos which fell to communicate anything more than a badly composed or executed photograph or image.
The sense of sight forms or communicates with the mind which forms preceptions unless you are blind. In which case the mind doesn't form a preception or image (by sight).
