Shoot your brains out.
Just start shooting if you are new. Learn composition by doing it.
You'll be amazed.
Block out all distratctions. Go off on your own (no hubby, no kids,
no pets) and just look at things. Then shoot them. You will be
training your photographic eye for beauty. Sounds mushy, but you'll
soon see what looks good. It should be a private endeavor... and
I'd disagree with some other posters about posting your shots early
on... if you are sensitive to criticism then keep photo's to
yourself for awhile.
When I started about 25 years ago I had a rule (that I quickly
broke) that I should get 1 really good picture out of a roll of
film. So say you should get a good or very good one for every 20
pictures (i.e. new subjects). As you learn to compose it will give
you something to then learn the technology to improve. Macro shots
are easy "beauty" shots because they are isolating and simplifying
your subject for you. Try these. Look at things the way a normal
person doesn't take the time to do. You'll be pleasantly surprised!.
I can't tell you how lucky you (we) are to have digital cameras
now. If I had one 20 years ago... No film charges, unlimited
frames, instant results for review, the web for forums like this.
And then there's Photoshop!!
Good luck.
