- | Exposure to the right (ETTR) is a technique of setting the exposure of a scene such that few or no pixels are are over exposed (blown out) thus maximizing the information captured without loosing information to over-exposure. | + | 在安装魔灯前你需要: |

+ | * 要有耐心。魔灯有很多好康的插件。但是它们其实非常简单,你只要用过一次就会登dua郎力。 | ||

+ | * 你可以在相机设为 **Manual (M)** 时按下menu打开设置来查看固件版本. | ||
+ | * 在你试图在魔灯不同的固件版本上运行魔灯不会发生任何机毁人亡的事故。魔灯会在启动前检查相机的固件版本。如果你就是头铁要试一试,魔灯会显示一个错误,但在拔掉电池后重启相机屁事没有。如果你使用比较旧的魔灯版本,你的相机只会让LED灯不断的闪烁,但你还是要重新安装电池。 | ||

- | Note: If Link to DUAL ISO is set to OFF, the module will not calculate the required DUAL ISO and the image will only be set to meet the ETTR requirements. | ||
- | **Show debug info**: ON OFF. Will show some of the important calculation results of this module. | ||
- | |||
- | ==== Visual Feedback ==== | ||
- | |||
- | If you want more visual feedback to see how the image is (and you will need it for **Always on** and **Auto snap**), enable histograms and raw zebras: | ||
- | |||
- | In the **Overlay Tab**, first make sure **Global Draw** is: **On, all modes**. | ||
- | |||
- | Then in the **Overlay Tab** you scroll down to **Histogram** and press **Q** to configure: | ||
- | |||
- | **RAW EV indicator**: | ||
- | |||
- | Also in the **Overlay Tab** you can scroll to **Zebras**, press **Q**, and make sure that **RAW zebras** are ON. The **RAW zebras** will show on the image itself to mark the areas where a color channel may be overblown. | ||
- | |||
- | |||
- | |||
- | ===== Setting it up ===== | ||
- | |||
- | ETTR in RAW images | ||
- | |||
- | 1. Go to Canon Menu and set Image Review: hold (This gives you a change to review the RAW histogram until you press half shutter to stop the preview, 2 sec is too quick to analyze the histogram but you can set it as desired NO LESS THAN 2 SEC! | ||
- | |||
- | 2. Put the camera in manual M mode or Av mode (either one since you must the aperture yourself), and set ISO to any number except in Auto. It wont work in auto! | ||
- | |||
- | 3. Press trash button to enter ML menu. | ||
- | |||
- | 4. Go to the Expo Tab and enable Auto ETTR by pressing set. | ||
- | |||
- | 5. Press **Q** if you want to change ETTR details. | ||
- | |||
- | 6. (optional) enable Global Draw | ||
- | |||
- | 6.1 Press **Q** and move to Overlay Tab. Make sure Global Draw in: On, all modes. | ||
- | |||
- | 7. (optional) enable Zebras | ||
- | |||
- | 7.1 Scroll to Zebras, press **Q**, scroll to the bottom and select Use RAW zebras ON. | ||
- | |||
- | 7.2 Press **Q** | ||
- | |||
- | 8. (optional) enable the Histogram | ||
- | |||
- | 8.1 Scroll to Histogram and press **Q** | ||
- | |||
- | 8.2. (optional) Scroll to RAW EV indicator and select ETTR hint by pressing set. | ||
- | |||
- | 8.3. Press **Q** | ||
- | |||
- | 12. Press trash button to exit ML menu. | ||
- | |||
- | ===== Usage ===== | ||
- | |||
- | You are highly recommended to use a tri-pod or other support. | ||
- | |||
- | ==== Always On mode ==== | ||
- | |||
- | 1. Frame you subject and set the aperture (for the DOF) and shoot a test photo. | ||
- | |||
- | 2. Now look at the display and you should see the image with the histogram and the zebras in the over exposed areas (if you enabled them). | ||
- | |||
- | 3. Shoot another a photo and repeat to step 2 until your photo is not over exposed (few or no zebra lines, and the exposure curve up to the right side of the graph). | ||
- | |||
- | ==== Auto snap mode ==== | ||
- | |||
- | 1. Frame you subject and set the aperture (for the DOF). | ||
- | |||
- | 2. Press the shutter. | ||
- | |||
- | 3. Now look at the display and you should see the second image with the histogram and the zebras in the over exposed areas (if you enabled them). | ||
- | |||
- | ==== Press Set and HalfS DblClick modes ==== | ||
- | |||
- | 1. Frame you subject and set the aperture (for the DOF). | ||
- | |||
- | 2. Press the Set button or quickly half-press the shutter release twice depending on the mode. | ||
- | |||
- | 3. The camera will go into live view mode and will step through a series of exposures trying to find the proper exposure for the scene and then the camera will go out of live view mode. | ||
- | |||
- | 4. Do not recompose your shot. Shoot the scene. | ||
- | |||
- | ==== Using the histogram ==== | ||
- | |||
- | Inside this histogram you may see near the top-left of the graph, in white lettering, the letter E followed by a number which represents how far you can go, in EV numbers, to reach ETTR, i.e E1.2 | ||
- | |||
- | Inside the RAW histogram near the bottom you may see colored circles with numbers inside which represent the overblown channels (R, G, B) and the number of EV of over-exposure. | ||
- | |||
- | If there are overexposed areas you will see RAW Zebras in the color which is overblown. | ||
- | |||
- | Take another picture without changing the scene and you will see how the camera settings are adjusted to meet the ETTR requirements. | ||
- | If the camera beeps it means that the photo is out of specs and you should shoot again. | ||
- | |||
- | ===== Convergence to results ===== | ||
- | |||
- | With the **Always on** and **Auto snap** setting which takes images, it may require at least two images (sometimes three or four) to come up with the proper exposure. | ||
- | |||
- | When the algorithm cannot find an adequate exposure it will beep twice and give you a message in the LCD screen. ETTR: expo limits reached, indicating the ISO and speed limits used. | ||
- | |||
- | When the algorithm finds an adequate exposure it will beep once and give you a message in the LCD screen. ETTR settled at ISO xxx and the shutter speed. | ||
- | Note: the image review time in the LCD is set via Canon menu in Image Review. | ||
- | |||
- | ===== Raw histogram use ===== | ||
- | |||
- | It is best to enable RAW Histograms via Global draw. This will put a little histogram on the LCD during image review. | ||
- | |||
- | If you also enabled RAW zebras via Global draw, you will also see, if any, areas of the image are over-exposed. | ||
