Zone Matching in 5D

seeyf · 26th November 2005

Hi, was exploring the features on my new 5D and found that when selecting the ISO there is a Lo80 and Hi200 option. The instruction manual (pg 54) says that its for Zone Matching but its not very clear on what it does. So, what does this "zone matching" thing do?

zone matching is very helpful when the condition is quite hard to shoot.. like getting over expose easly..esp white color... switch to zone matching will be best and easlier to shoot.

Hiee....

Hers's what it think it does. It basically treat the image specially with thwo types of imgae in consideration....

1- One that have "more to the right side of histogram" information - hence it gives "more" dynamic range for the camera to represent these highlights information. - High Key

2- One that have "more to the left side of histogram" information - hence it gives "more" dynamic range for the camera to represent these shadow information. - Low key

So if your image have more of the information skewed by reference from histogram to the right - then High key would be better to "spread" the information better to give more details on the higher highlights area.

Similarly,

So if your image have more of the information skewed by reference from histogram to the left - then low key would be better to "spread" the information better to give more details on the lower shadow area.

Sounds chim?
Well just take a photo of a flourescent lamp (turned on) in the two modes and you can see the difference on the avaialble detail information - for high key - you would probably be able to see the gradual curvature fo the lamp tube. But for low key, you will see a white patch instead. You can do the opposite for the shadow area - take image of a dark area in the room...see the difference in the two modes..

Ha... this time go to Putrajaya forgot to try this high/low key thing...
