Tom, you have to set you shutter speed and Aperture to match the lighting, you cant simply just pick two settings. I mostly meter of the ground in manual mode. If you are going for depth of field select a closed aperture like F11 0r F16 and then adjust your shutter speed so the metering in the camera is centered ond not to left or right. Remember you dont want anything lower than 1/30th sec or you risk camera shake and a blurred pic.
Opposite applies if going for a shallow depth of field...select 2.4/f4 and then meter and adjust your shutter speed so the needle is again centered. You will most likely have a fast shutter speed this way which can also be using for freezing action etc.

Also make sure you are not confussing the exposure compensation arrows with the main exposure indicator.

Anyone else care to chip in here !!!!!!!!!!

Stick with Raw 100% if you have the time, i just shoot jpeg for speed in dev times

Yes half hold the shutter button and move either the aperture or shutter speed so needle is centered. There are times when you would not meter of the ground.......ie you have a lot of sky in the pic. Green grass and grey concrete are good surfaces to take your meter readings from.
For weddings if i am shooting in manual i use a lightmeter with a cone and always take incident readings (light falling on subject) by holding meter at subject and pointing towards camera. The other type is reflective reading were you measure the light being reflected by the subject by pointing the meter at the subject away from the camera. This is less accurate and can be fooled by large areas of white or dark tones........ie a brides dress

your camera will have different metering options like spot metering, average, centre weighted etc, I always tend to use centre weighted and spot. Spot is good for portraits taking a reading from say the skin, while i use centre weighted for landscapes etc.

Like Andrew I have a 350D, my only fault with it is it is a little too small, a battery pack would help here. Tom once you understand what Neal has so ably explained to you on the aperture – shutter speed settings, it will become second nature for you to choose between aperture and shutter speed priority modes... I use aperture priority for most of my shots and find I have little to alter on the exposure side for most of my pics in Ps. With the 350 and 400D it is easy to take readings from the shadow part of a scene, as well as a general exposure.
You may also want to look at the white balance settings in the menu, there are seven or eight different displays, Auto, Daylight, Shade, etc etc.
The area I find most difficult to get correct is the sky, but have started to use a Cokin ND graduated filter which is helping.

Pat........would you believe me if i said for most of my press work i use program mode........ok i do keep an eye on the SP and Ap but i figure these companies spend millions on development and research and 99/100 i get the desired result. I use TTL flash with a Metz 76 and its just a case of hitting the +/_ to get my desired fill

Neal I think a lot depends on the situation that you find yourself in, the camera is usually in a program mode while walking about, ready for a "grab" shot, when I have time to take the picture I then I go for AP or SP. I have three flash units, all rather old from my B&W and transparency days, i only use the built in flash on the Canon these days.... the price of modern flash stops me from buying.....

Neal

I tried in manual mode, but could not get the needle even near the centre, so what i had to do is put it in p mode then go back to manual with those settings.

what am i doing wrong?

Ok say for example the program reading gave you 250th sec at F8, when you go to manual mode with these settings and you start to move the aperture up and down does the needle move then !!!!!!!!!!!!!!!!!!

Yes you first choose your aperture and then move the shutter speed so the needle lines up in the centre. If the needle does not make the centre then your aperture is too closed and you need to open it up. Try it one stop at a time until you are able to get the needle in the centre.

say f8 at 250 sec gave correct exposure !!!!! so also would

F5.6 at 500sec, F4 at 1000th sec, f11 at 125th sec and f16 at 60 sec

Can you spot the relationship !!!!!!!!!!!!!!!!! as one goes up by a stop the other goes down by a stop but all the readings you see with be correctly exposed !!!!!!!!!!!!!!!
