Hi Rick,
Welcome to the Challenge!
Here's the usual information I post for the Challenge (soon to be enclosed within a web page, for easier access!):
The APUG Photo Challenge is a monthly bash where members go and make a photograph fitting a given theme and upload the result to the APUG Challenge Gallery. The original idea came from APUG member (and B&WP UK editor) Ailsa who said (in part):
"I was pondering the other day that I often produce my best work when given a brief or a project, whereas when an idea is self-imposed, I tend to just float around it and not really knuckle down. So I got to thinking, how about setting up an APUG photographic challenge thread?"
"The themes can be as open or as specific as you like, within reason - obviously there wouldn't be much point in telling me to photograph a tree in Yosemite, unless the person setting the challenge was willing to pay my air fare and accommodation..."
"...it could be a great opportunity to break out of our usual styles and try something completely different."
In answer to your specific questions - End of June is the closing date (but we tend to be pretty lenient about it!), please feel free to post multiple entries and "macro" has not been clearly defined for this challenge (which, in my humble opinion, is a good thing - I'm looking forward to seeing everyone's interpretation of the theme...!).
All the best,
Frank
