 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. 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.

 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. ​ To see this aim to an area with higher more light and take a pic. 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. ​ To see this aim to an area with higher more light and take a pic.

 When the algorithm finds an adequate exposure it will beep once and give you a message in the LCD screen.

 Note: the image review time in the LCD is set via Canon menu in Image Review. ​ You may want to set it to atleast 8 seconds so you can see the results in the LCD before it turns off. Note: the image review time in the LCD is set via Canon menu in Image Review. ​ You may want to set it to atleast 8 seconds so you can see the results in the LCD before it turns off.

-===== 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. ​ This histogram can show an ETTR hint (how many EVs are required to reach ETTR), or the Dyanmic Range of the image. ​ It will also show the clipped channels via colored numbered circles. 
- 
-If you also enabled RAW zebras via Global draw, you will also see, if any, areas of the image are over-exposed. ​ Black will be completely overexposed,​ then you can see red, green, and blue channels clipped areas shown with their respective colors. ​ White will be dark areas completely under-exposed. ​
