They are metering modes for your camera and influence how the camera calculates the exposure. Your EOS 450D (if this is what you have) according to docs has:
• Evaluative 35-zone (this is matrix metering)
• Partial 9% at center (this is a kind of center weighted metering)
• Spot 4% at center (spot metering at the 4% spot in the center)
• Center-weighted average (center weighted)
(I don't know how to set them - so you'd have to consult your camera manual)
When you frame your shot, the exposure is deremined by the camera internal software and a light measurements taken from a small metering sensor (kind of scaled down sensor with only a few pixels). The metering mode determines what parts of the frame is used to determine exposure:
• it may use nearly the whole of the frame (matrix metering)
• it may use the large part of the frame with the priority given to central area of varied size (central weighted metering)
• or it may use a very small central part of the frame only (spot metering)
Does it explains it?
I'd like to apologise to you and voodoochild for not replying earlier, thanks alot for replying with so much details, I really appreciate it.
I will actually read through my Manual even though I do have a rough idea of how to do it, I was checking out my camera yesterday and noticed a button to select metering, there were some weird rounded square shapes you have to select to take the right photo. I will read up a bit more on my manual though.
Thanks again, this is really helpful.
That's very cool.
In auto mode with matrix metering it will be almost impossible to make a silhouette. To get an idea of it you could just wack it into manual mode, set a random aperture of around f/10 and just keep increasing the shutter speed and taking shots. Eventually you will end up with a silhouette, but the subject must be stood in the foreground with a bright background, ideally with the sun behind them so their face is not very illuminated.
Google metering and how it works. It is hard to explain, so I suggest just putting your camera into aperture priority and playing with the metering buttons and things will become clear.
Aah, that seems much easier, i'm thinking maybe I could try taking a similar shot at a tunnel where lots of light is coming through.
For instance if someone is stood light at the end of the tunnel with light surrounding them and i'm at the other end taking the shot, I could try out different shutter speeds and maybe even aperture and see what I can come up with.
Thankyou.
This is probably the only one I've every done:
As said you just need a bright back light in low light conditions.
That's pretty cool.
Heres one i managed to get at a short firework display.
That's so cool!
Took this at the recent Southend meet.
Wicked photo.
As said above, put the camera in semi manual mode (Av Tv A T etc) and point the camera at the sky/light source and set the exposure by changing the sutter speed or apeture. Dial in one stop of under exposure and then compose the photo whilst keeping the exposure locked on the bright area. This will expose for the sky / light area and the rest will come out black
I've never used Av Tv modes, this will be pretty cool, I'll test myself for sure, i'll try different modes and post several pictures, then you guys can tell me which was the best
What test is it?
Here is one of mine.
A digital photography practical test.
Nice photo
Just wanted to say great to see people sharing info to help others so freely! Only joined this forum yesterday but learning alot already. I'll have to try some sillouette shots now
I totally agree, I have got so much help from here <3
i just set the exposure for the background.
taken on film (400iso)
i took a similar photo (in colour) about 2 years earlier on digital and the sunset colours are absolutely sublime (perhaps a little bit fake but heyho, it makes a striking image on the wall.
That's awesome, I prefer the colour one.
