A great article is 20 Photography Tips For Beginners by Spencer Cox on PhotographyLife.com. In fact this is a great site for many photography tutorials or articles. And not just for beginners - good tips extend to all levels of expertise. Following is a list of contents.
A summary follows. I have any of my additions in italics.
1. Education First, Gear Second
Famed National Geographic photographer Jim Richardson once said “If you want to be a better photographer, stand in front of more interesting stuff.”2. Shoot for Yourself, Not Everyone Else
To that end, if you’re shooting for Shares—or likes, or +1s, or comments, or whatever—you're doing it wrong3. Limit Yourself on Purpose
Setting limitations on yourself—whether it’s gear or time of day you’re ‘allowed’ to shoot or even limiting yourself to ONLY black-and-white for a month—is one of the best ways to grow. Master one at a time4. Find Your Niche
You can’t master adventure, travel, street, and wildlife all at once… or possibly ever. It’s always better to go narrow and deep than wide and shallow.5. Slow Down
Shoot as if you only have 36 photos at your disposal.Finally for those who are ready for some more advanced techniques the following video addresses some I've not seen before and the presenter "gets on with the business" and doesnt spend 20 minutes telling you who he is or what he's going to address :-)
6. Get Connected, Join a Community
Photographing in isolation can be great, but having a group of photo lovers handy to point out mistakes you might have missed or offer perspectives you may never have thought of is incredibly useful.As long as you choose who to listen to - many people are technology freaks who dazzle you with numbers and technical jargon that you may find is beyond your current understanding.. Seek out the innovators and the rule breakers if you want to allow creativity to reign.
7. Practise, Practise, Practise!
Ask about practice techniques, research great free educational resources, or engaged photo groups, or life-changing photo tours.
