Here’s a great resource for beginning photographers (and, for that matter, intermediate and advanced photographers needing a skills/technique brush-up).
These are a collection of lessons Alexandre Buisse did on reddit.com/r/photoclass a couple of months back.
There’s some great stuff in here, including basics such as exposure and metering modes up to more advanced stuff, like composition, post-processing and workflow. It even touches on the RAW versus JPEG that I alluded to in my previous post.
