We had heard many points of view on the alms giving, whether to participate or not. We are "a little bit Buddhist" and decided to partake 'properly', ie actually GIVING rather than intrusively photographing, and are glad we did so.
Just a word of caution, though ... try to organise yourself to have an ABSOLUTE limit on your spending for offerings. There are so many monks and the stream of them goes on for such a long time, that you may find - as we did - that you run out of food to give, which means that "helpful" locals keep thrusting baskets in your hands (if you let them) and the total at the end can be quite high!
