I'm still learning and have been asking hell lots of questions on CS too.
But everytime before I post a question, I check out google, photography websites and do a search on CS forum itself.
Even now, I'm reading from this website http://www.weatherscapes.com/techniques.php
After going through, sometimes I still post questions to double confirm and also to see what majority of the CS'er do.
I bring my camera to work, so that I can practice while reading.(I got short term memory la... )
Using my Canon EOS 40D, EF-S 17-85mm IS USM.
Anyway, about the indoor, low lighting environment, I usually increase my ISO to not more than 1000(As the noise will be quite terrible.)
Best is you use tripod(which is very troublesome)
For shutter speed, I uses fast shutter for handheld.(Trial and Error)
For aperture size, depends too...(Trial and Error)
With 480speedlite and a diffuser.
Seriously, I do not know whether if it's the best method, but at least it still a good picture.
Hope this help abit.
Anyway Cheer up though!! Chill chill~~
