請問影正片時, 是不是影淺色的地方要over 1級, 影深色的地方則要under 1級??

那麼如果是一半山一半藍天, 那時該怎麼辦呢?

謝謝

Depent on what will you choose. If take under one step,lighter parts of subject should get more details and colour saturation to be more rich. If over one step will be go to other way.

--> The metering from camera is middle grey.
Expose more make the subject brighter in the photo.
Expose more make the subject darker in the photo

This applies to positive and negative.
Positive slide needs more accurate exposure though.

那麼如果是一半山一半藍天, 那時該怎麼辦呢?
1. Reduce light from sky by :
a. using a Gradual ND filter
b. using a black card (for long exposure only)
2. In Photoshop using blending technique.
Pls refer to www.luminous-landscape.com

Happy shooting !

影正片測光通常都偏重光位測光,如果測光偏向暗位,咁放出來時就會冇晒層次o架啦....

This metering question has nothing to do with slide film. The technique of using EV compensation applies to slides, negative film and also digital cameras. It is just a way to compensate the problem associated with the metering system.

If you are a hard-core slide film shooter, then you should know that most photographers bracket heavily when shooting slides. This is because of the small exposure latitude with slide silm (much smaller than negative film).

一半山一半藍天 .
Depends on when you take the photoes .
If time is about 12:00pm and with strong light . using the GC-gray filter with the gray part covering the blue sky . Still using the bracket exposive with average weighting . ( -0.5EV , +- 0Ev and +0.3-0.5 EV)

however if the time is about sunset , then you need to thing whether you need to have to take the hill as part of object in the photo , or , leave it underexposure but with only about 1/3 in photo since it will sometime useless when using the mentioned filter to take this kind of photo at sunset .

影正片跟菲林或數碼完全係兩回事，因為正片對曝光正確要求非高，只要相差 1/3 級已經唔同o左，所以影正片的影友對一些沒有十足信心的情況下都會用多重曝光影多幾張，如果張片影衰o左真係冇得救。
