Couple of photography questions...
Discussion
I've just got myself a Canon S1 IS as it has a lot more manual settings than my old point-and-click and I want to learn more about photography.
But I have a couple of questions:
I understand that to create a blurred effect of a moving object in a picture the shutter needs to be open for a long(ish) time. However, having tried this all the pictures are overexposed. Is the only way to overcome this by increasing the f-number? If so, I only go up to f8 so generally in day light the max time to keep the shutter open is fractions of a second whereas I'd like 5 seconds. Is the ISO number anything to do with this?!
If there is a decent website that explains stuff like this (i.e. for dummies) I'd appreciate a link.
Thanks in advance!

yeap.
Higehr the ISO the shorter time you need to expose the pic.
So you need a low ISo (less sensative) 'film'. But your camera may only do ISO100.
So if ISO 100, F8 isnt enough you may be stuffed if its over exposing , you may be able to use exposure compensation or a filter to achieve what you want.
Edit - daylight for 5 seconds on that camera may be well past what it allows? Most cameras only cater for 95% of the shots 95% of people want.

a 5 second exposure in daylight is beyond even top range slrs without using a filter, so I wouldn't worry too much if your camera can't manage it either. If you really want to go this slow, buy yourself some ND filters. but bear in mind that there will probably be a lot of noise in the pictures you take with such a long exposure
If you're trying to capture some blurred movement try exposures in the region of 1/8th to 1/60th of a second to start with - set this through the shutter priority option on your camera. Experiment a bit and see what gives the results you like.
5-30 seconds would be the sort of time interval for capturing moving car lights in a night time street scene. You should have your camera on a tripod or some other solid mounting for this.

In M mode up & down on the 4 way button alters the aperture and left/right alters the shutter speed.
Why use such long shutter speeds in daylight?
Surely it's better to learn on a half decent compact first?
Can you tell my wife is against me buying an SLR?

Actually, to learn and understand the basics of photography, a cheap manual film SLR will do the trick nicely.
It was good enough for the young Simpo, bah humbug

What?
And spend all that money on film, then money on processing, not be able to check the pic and learn from your cockups and get all those pics backfrom the photlab that you could have deleted and got nice ones instead.
I think like many others, digital camera's are what have got me properly interested in photography.

True, but I was thinking of people on a budget: compare the price of a DSLR with a second-hand film SLR. You're not going to get a full understanding of photography with a compact.
In car terms, which teaches you more about driving and car control, a RWD manual or a FWD automatic?
The debate is not film vs digital, but compact vs SLR.
