I hate those 'for dummies' books - so 'dumb'.
There is so much information out there for beginners. Many websites, youtubes, CD's and of course good old books. Many of the magazines include sections for learning. I'm a facebook user and have "liked" more than a couple of photography FB groups. Some of these daily post tips of the day and I think I tend to learn best in little pieces. Spoon feed me a tip daily and I can digest that better than reading chapter after chapter (although I do that and it has been helpful. Depending on how up-to-date your local library is there may be books there. I find that these tend to be the read once and put on the shelf books so library may be a good option. Libraries also may have periodicals with may have "new to SLR" articles. Your local camera store probably has a selection of resources too. But in today the web is the way and it is free. Challenge is to weed out the wheat from the chaff. A lot of what is out there is really "info-mercials" designed to sell you stuff.
Here are a few I follow
Facebook pages
Nikon (of course they have their own FB page - pedestrian but good source of official information)
N-Photo Magazine ( tries to get you to subscribe but does post lots of good stuff)
Digital Photography School - good daily tips - wants to sell your their programs
Adorama - this reseller has some great learning video's on their Youtube channel
The Photography Podcast - learn while you drive if that's your way
Photography Life - "
Photography Life provides various digital photography reviews, articles, tips, tutorials and guides to photographers of all levels"
Digital SLR Photography Magazine - good one
There are many more. Including Nikonites
Nikonians - another online forum - IMHO a little (not lot) more intense than this site but a great source of information and discussion.
Youtubes
B&H has a great series as does Adorama. Of course there is more than a subtle effort to get you to like their store too.
Digital Photography Cafe - done like an interview show
PhotoVideoEDU Program ok
The Photo/Video Show - alright
thefrugalfilmmaker - cheap and cheesy but interesting - and I am err frugal too.
Digitalreview TV - some oriental guy who makes lots of youtube videos - opinionated but funny (well sort of) I've watched lots of his.
Webpages
Digital Photography - Tips, Techniques & Digital Camera Buying Guides & Reviews at BrightHub.com
Digital Camera News, Reviews, Tips and Techniques | Digital Camera World
There are many more but I gotta run.
This is just a sample of those I've stumbled upon and not an endorsement of any in particular. Just google it. "DSLR Tutorial" for example will get you gobs of stuff to sift through.
Maybe some others will post their recommended learning pages to 'like', subscribe or bookmark.
Enjoy learning it is part of the hobby - it never ends.
