Like I said, these are suggestions and most of them are probably crap.
👆 The real reason there's no poop emoticon. 🤣
(I'm just kidding - there's good food for thought, there.)
I agree, they aren't really challenges. The collection of challenge posts as a whole are not really any one thing, actually. They are:
1. Goobers sharing a picture as a story (as I think @DangerDave put it)
2. A competition (sort of... the categories are only loosely defined and there isn't really a proper selection criteria for the winner). I'm not sure how many people really see it this way.
3. A challenge (to what - share more photos?)
4. An educational opportunity, which has profited some of us - but that's not really the focus, is it.
So, maybe there should be different threads to deal with these different things. Me, I'm happy with #1, would really like more of #4, and am kind of interested in #3, but the challenge I'd most like would be along the lines of what @StephenL suggested above (though I wouldn't restrict it to a weekend - maybe a whole week, and I'd change the theme often and keep it broad, like the F-Stoppers challenges I spoke of previously.) See some ideas below.
Personally, the things I like most are learning and improving, so I'm glad we have some pros and top-notch amateurs who are willing to share. I've already learned specific techniques from @rtwPaul (hip shooting, but also seeing how he edits) and @Awais (macro) and @Glenn_Smith (flash+macro), and I see the learning potential from too many other people to name in these two weeks. So I hope those opportunities continue. It might be nice to know when it's safe to offer a critique or ask questions of someone else's work. For my part, please consider it always safe to do so. I'm not expecting many questions, but happy to hear if someone think I could improve something.
Some specific challenges that might be interesting:
a. Post a bad photo that you think has potential and see if cream rises to the top through collaboration.
b. An occasional editing challenge - someone shares an unedited photo and people turn in their efforts to improve it - with the understanding that they will also be willing to explain how they did it.
c. As mentioned above, a 'best shot this week' challenge. Maybe not so challenging for the people who shoot every day, but quite challenging for those of us with (mainly) office jobs, I should think.
