Someone gave xrapidx a 40D

mmm
maybe the 50mm1.8 can help in the lowlight
plus xrapidx is at iso800 - can still go to iso1600 (very good on 450d)

Both of those would prob help. :)

@ xrapidx - in case you weren't sure IS helps keep you steady not your subject.

I'm not that much of a noob :p

BTW - the dog and the girl were sleeping. :)

Ok - I've taken some test shots, looking at them now.

I'm hoping they were still breathing though? :D
 
Here's the focus test, maybe I'm over fussy, or doing something wrong, but the top part of the black bar in the crop doesn't look right:

Overly fussy. :p
 
yeah
that's f5.6 (wide open, for that lens at 55mm)
stop down two stops - will be razor sharp
 
How do you guys know what aperture to use? I was reading through the links you sent me ldmelsa and they said the square root of (depth of focus you want * 375) ? Or did I misunderstand?

Is it just experience, or is there a nice way to work it out?

don't think so much
just put it on "P" and watch your shutter (that it does not get to slow)
use a smaller fstop when you want more depth of field
use a faster shutter when you are photographing fast moving subjects

for now, don't worry so much

Thats been the issue, P is what returned the bad shots on the previous page.

If, using the previous example of the girlfriend and her, with only reasonable light, what would be the correct shutter speed not to get any blur (guestimate)?

Stop using P.

Try AV for a while. You'll soon learn how it affects DOF.

Back to your qn - try for 1/50 and up for slower moving objects.

why?
it's very smart these days
I use it all the time

Really? When I'm taking a photograph I either want to control the DOF or the shutter speed and know what sacrifices I'm prepared to make. In P the way it shifts aperture and shutter speed seems almost haphazard at times.

EDIT - I am a fan of P for when I'm doing flash photography (but only when I'm using the flash as the primary light source). I know - I have no shame. :D

oh
the d90 has a p shift thing (you just scroll the weal until you get a combo you like)
I use shutter priority when I'm photographing fast stuff
I use aperture priority for the flash (if I want that slow shutter to get the natural light)
other than that I use P and autoISO (minShutter=1/60 maxISO=1600)
I use exposure comp to avoid blowing out highlights
the P is very smart - it tries to select a sharp aperture & fast enough shutter (it also knows when the VR is on)

same thing with my 300d (except for the p shift thing - or did it have that?)

The 400D also has a shift it just takes longer for it to eventually get to where I would have wanted it in the first place so why bother. :)
