Do you a google search and you will find some websites with photo assignments. Bryan Petersons books have so good exercises in them for beginners
Yes, I know about Google... I can even use that wacky advanced search feature thingymadoodle... or is that thingymagoogle?
For the record, a search on the phrase "photo assignments for beginners" returns around 76,000 results. The first is another photo forum, the second is TPF, and the third offers tips like "capture the personality of your pet" but fails to make any mention of f-stop, shutter speed, or any other technical term and has a forum that nobody has posted in since 2010.
I also already have Bryan Peterson's books, have watched countless web videos, and routinely dig through the forum archives and the Tutorial sticky. Oh... and I've read my camera's manual from cover to cover.
Like the OP however, I think I would enjoy having a sense of direction from more knowledgeable others at this point. Bi-weekly assignments with a specific objective would channel much of that noob energy that seems to so annoy some of the regular members. Members that want to rub virtual elbows with us photography "toddlers" can do so and those members that don't have either the time, patience, or energy can keep their seats at the "big folks" table.
I do enjoy (mostly) visiting this forum. It's becoming a habit and a way to unwind after a long day (or start a long day in this post's case).
