One of the most asked questions on forums I find is "What are the best resources for beginners?" Usually "resources" is replaced by "videos", "blogs" or whatever. I also recently met someone who asked me the same question so I promised them a list of the things I found helped me the most not only in the beginning but throughout my short time as a photographer thus far.
I'm a real YouTube junkie and will sooner set aside time to watch a video before I read a blog article if I'm looking to learn a technique. Since I'm a real junkie, I use playlists often to bookmark videos. This is my beginner's playlist that I link back to often. One channel I always recommend for beginners is Mike Browne's YouTube channel. His channel is by far one of the best when it comes to teaching fundamentals. His production value isn't quite as high as some other channels out there but it's been continuously getting better over the years and is a very no nonsense channel - no clickbaiting and is very much down to business.
Here are my other favorite videos, playlists and blogs:
Getting Started with Lightroom 5
This video is quite long but will take you through all the basics of getting to know LR5 and how to use it effectively. At the end of the day you need to practice and find your own style but this is a great place to start to learn the program's workflow.
The Art of Photography composition series
One of the videos in this playlist is actually in the beginner's playlist linked at the top but this series of videos from Ted Forbes is simply too significant to ignore. I would also highly recommend simply subscribing to The Art of Photography channel - Ted's production value is really up there and he generally eschews the whole clickbait stuff that runs rampant everywhere.
Eric Kim's blog
I really like referring to Eric's blog if you're into street photography because he does a pretty good job of covering all aspects of the genre. Not only that but he's all about motivating people to just get out and shoot, which can be nice whenever you find yourself in a creative rut.
Adam Marelli's Bridging the Gap: Classical Art for Photographers
This is a true gem on YouTube. It's a 1.5 hour long video on composition and how to help get your images to read better. The lessons here apply to all genres of photography so it doesn't really matter what your preference is, you will find something here that will make your photography better.
Ming Thein's blog
Ming's blog isn't just a photography blog - it's perhaps the best photography blog there is. What I like about Ming is that while the gear is certainly an aspect of it, it's more a secondary topic. Quite often his blog posts emphasize the fact that you can get amazing images with very little in the way of gear and it's entirely up to you as the photographer to know what you need for a given task and how to effectively work within constraints. I've not yet been able to afford one of his teaching videos but it's on my list.
This is the definitive guide for beginners to lighting and off-camera lighting. If you've ever wanted to learn to use a flash (or 20) and really take your images to the next level, this is the guide for you. The best part about it is that you don't need to shell out a lot of money for a TTL flash and expensive lighting modifiers but you can get by with very little cash and achieve some stunning results.
I have a whole host of favorite articles, videos, etc. but as far as photography resources, these are the things that have shaped me the most.
