Aperture and Shutter Speed. Advice?
Could someone tell me what apertures and shutter speeds go together. I often use aperture and shutter priority modes but I really want to try manual to over/underexpose and stuff. I'm using a fuji finepix S5000. It only has a 2 second shutter speed so I was wanting to try manual mode to make the aperture wider so night shots become a little more clear. So if you could just give me some photog to photographer advice on aperture+shutter speed combinations. thanks!...

for indoor with flash....normally is 1/30 or 1/60 wif f5.6...
otherwise there is no hard and fast rule... get a correct exposure and compensate if u want a faster shutter etc...

i think that what you need to understand is how to read your meter on the camera... because you have been using auto modes all this while, do dont quite know the concept behind exposures. i'd suggest you read up a photography book on these things because there is alots to type if i were to type it here...

night shot got 2 main types:
1. basic scenery
2. target subject. (mobile or stationary)
which r u going for?

duno if this will help.
assuming that the 'correct exposure' is a pail of water, what you want to do is to combine the aperture(like the opening of a tap) and the shutter(how long to keep the tap open) in order to get a full pail of water. overflowing would mean overexpose and not filled to brim would mean under expose. and the rate of flow from the tap would be the ISO( eg 100 would mean like 100 litres per min and ISO800 would mean 800 litres per min therefore makiing it a faster film cos the higher rate can fill a pail much faster.)
the camera would recommend the 'correct' shutter and aperture to get a full pail of water. from there, if the recommended shutter is 1/125sec and aperure 5.6, you can close the aperture to f8( hole become smaller, 1/2 of f5.6) and you will have to openthe shutter to 1/60 (longer, twice) in order to get the same pail of water.
the aperure, shutter and ISO all are measrue by doubling and halving. eg 5.6 is half of f4 and f8 is 4 times smaller of f4
likiewise shutter speed 1/60 is twice of 1/30 and half od 1/125.
manual control allows you to decide over the recommended cos for eg, if you have a bright light source included in the metering you are bound to get under exposeure cos the camera thinks that the scene is bright. you can either meter without the light source first then compose or compensate for the overexposure
so much for now. hope i not confusing you

just wanna add that this is just an analogy to getting correct exposure. of cos there are other factors that must be considered which may have not been mention here.
shttuer speed- freeze movement or to allow movement
aperture- allows you to decide depth of field.
your combination of shutter and aperture will depends on the depth of field you want or if you wan to freeze the movement...including your own hand shake!!

ive read a lot about it in the past 3 hours. tomorrow ill try out full manual control and do the whole thing with the stops until i get certain exposures. I'll also try auto bracketing so its a little easier for me to compare the different exposures.

the problem is, the S5000 only has a 2 second shutter. That's why it's hard for me to get right exposures of night scenes. i would have to make the aperture bigger. maybe ill upgrade to the s7000.

Hi there, fellow S5000 user,

Any lower (left) will be underexposed, and higher (right) means overexposed. Doesn't really have to be perfect, but you may use either the matrix metering or spot metering mode for more accurate reading.
For best reading, use a 18% gray card. You'll need to use the P-mode to meter the card (incident light) and then set the reading in manual mode, regardless of the indicator position. You shall get near perfect exposure this way.
