1.03更新的說明檔

主要更新
提供
1.ISO 50(選AUTO ISO不能用, 要自己到ISO設定選項裡面設定才能用)
2.LCD螢幕上可以有井字輔助線了(按相機背面 l口l 鍵 就會出現了)

有人可以貼一下比較圖嗎?
ISO50是否真的比較細緻...不知道細節的保留能不能和其他感光度相提並論
例如...Nikon D3(映象中...)就是從ISO200起跳 ISO100要手動 細節的保留好像還差200點

亮部細節會比較差,要找有爆亮的去試,就可知曉
只說白賊七是最會白賊的代表人物,就被刪文了...所以管理員認為正宗最會白賊的人是?...
有iso 50?! 趕緊下載來試試看,說不定打消出清的念頭...[無奈]
依照別人使用SD14的情況ISO 50
寬容度比較小~高光部分容易爆掉~
請問一下ISO50使用場合建議為何呢?

既然高光易爆, 勢必要在光不那麼強的地方用, ISO較低,
快門一定又不夠.
看到SD14 ISO50的細節似乎也沒ISO100好.
那麼不知道ISO50到底要用在哪邊..
前面攝友結論沒錯,
iso50犧牲了dr,但會得到較好的iq。

但我個人不會為了一點暗部細節去犧牲dr,
反而會把iso50拿來當放慢快門的工具,
不知如果搭配cpl使用(省nd鏡),快門能不能慢到拍出涓涓流水圖。

看來sigma對於dp1還蠻用心的,
幾次韌體更新都有增加實用的東西,
希望未來能夠加入即時histogram或可自訂那無用的數位變焦鈕。

Note for ISO50

This firmware upgrade provides users with the ability to capture images at low-noise levels. However,
ISO 50 has a narrow dynamic range unlike the DP1’s ISO 100 and above settings and
therefore may blow out highlight detail such as brightness or high saturation areas.
This means photographers need to work a bit more carefully.

To use the ISO 50 setting for the best results,
Sigma advises its photographers to pay attention to the following points.

Please meter accurately when using ISO 50.
The camera’s built-in metering system will produce excellent results under most conditions.
In high dynamic range settings, however, we advise using Spot metering and taking a reading of the brightest part of the image.
You can then adjust the EV by one or two stops to account for the brightness of that object.
We recommend using the Auto Bracketing function.

For shooting in critical landscape settings where ISO 50 provides exceptional detail with little noise,
we advise using manual (M) mode to shoot.
Meter carefully and then adjust the settings after taking a test shot and reviewing the histogram.

For regular shooting, Sigma recommends using Auto mode, Program (P), Aperture Priority (A),
or Shutter Speed Priority (S). Under normal circumstances,
the camera will produce exceptional results using matrix metering and the camera’s normal automatic functions.
If conditions require it, you may wish to adjust the EV setting to -0.3 for a little more protection of the highlights.

ISO50 can provide the exceptional result for taking the pictures of landscape etc with the fine details and the lower noise.
We hope all the photographers enjoy shooting the high quality images at ISO50.

謝謝這位版友的回答與資訊.
我想我理解了.
是為了提供更高畫質的畫面.
條件是 腳架 + ISO 50 + -0.3 EV(建議) 避免高光過曝及更好畫質.
承上 利用ISO50 達到慢快門拍流水.也是可以的.

感謝
可不可以改一下,讓對焦點的選擇能更方便一點呀~~~還有對焦的能力再加強呀~~~~
呼~~~~
這是小弟的希望啦
