I would have asked them "Is this photo worth posting?" "Does it look better in black and white?" "Is it too similar to what I have taken in the past?" and "Is it cliche?" What I hope they would have said was "Yes it is worth posting." and "No Sally, the black and white is OK but the color adds." "Yes it is typical of what you would photograph but different enough to group it with some of your others. Like these."
I am doing my best with only my husbands help. Hopefully I will be able to be in a setting like that again.
