Right firstly i'm pee'd at picasa for the links not workin
booooo!!! I'll get them on photobucket asap!!!
If i can offer any wisdom i will. Here are my rules/tips i implement myself though...
- Apperture vs ISO... Apperture wins all the time! I never take my ISO above 200 (400 if you're lucky!) Apperture can be raised all day long without effecting the quality of the image because its a natural adjustment... ISO is digital though, therefore increase the ISO sensitivity and you'll start getting loads of 'noise' on your pics - eugh!!! So whack a high apperture when you are shooting in low light!
- Shutter speed FTW! ... where possible, i hold at least 5 secs of shutter speed, but ALL my nighttime ones are achieved at 30 seconds of exposure time... I'm waiting for delivery of a radio controlled device so that i can set the apperture to its lowest setting and the ISO... and hold the shutter open for like 10 minutes and see what happens - the longer the shutter is open on stills, the richer the photo! (IMO remember!)
- Composure 'self... if theres one rule i follow for shots and their composure, keep the focal point in focus (duh!) and always work in 3rd's! i.e. slap the focus of the image 1/3 of the way from the bottom or 1/3 from the top... you can achieve this with cropping afterwards too, but try to take shots so that you dont need to crop them if possible
