Camera FV-5 has a built-in exposure bracketing feature. Bracketing means taking multiple shots varying some parameters between them. Therefore, exposure bracketing produces multiple shots with different exposures. On other DSLR cameras, this feature is known as BRK or AEB (auto exposure bracketing).
Exposure bracketing is useful to:
- Capture a photo with good exposure when you don't know the correct exposure beforehand, or you think that you would need to change the exposure after taking the photo.
- Capture a broader dynamic range scene: either you can expose for a bright area or a dark area but not both. Later, with the bracketed pictures, you can make a HDR picture on the computer, or using other applications.
This is the Camera FV-5 interface, when bracketing is not activated:
Notice the exposure meter on the lower right corner. The red mark shows the current exposure compensation. At +0 EV, the exposure is at the automatic metered speed.
Now, tap on [MENU] icon at left bar, then BRK. The bracketing settings dialog will open:
The dialog contains the following settings:
- The upper display shows the total number of frames. You can take from 3 up to 7 frames. You can tap on the + and - buttons to increase/decrease the number of bracket frames.
- The lower display shows the exposure compensation step between frames. The smallest EV step is device dependant, but a typical value is half stop (0.5). However, there are devices with 1/3 EV step too.
- Finally, you have the exposure meter with the red mark at the center of the number of frames, and white marks showing the rest of the bracketed pictures' exposure compensations. You can see this exposure meter on the main display, too.
When you are done adjusting the number and step of the bracked pictures, dismiss the dialog by tapping outside it. Check the number and exposure of the pictures to be taken on the exposure meter at the lower right corner.
Exposure meter with 5 frames at 1 EV stop increment between them.
Also, if you change the exposure compensation (EV), that will affect the position of the bracketed pictures' exposure compensation.
Exposure meter with 3 frames at 1 EV step increment between them, and a −1 EV compensation.
EV compensation plus bracketing lets you to take multiple dark or multiple bright pictures, depending of the sign and magnitude of the EV shift.
When bracketing is not working, check the following:
- You are in program mode (“P” icon at left). In speed priority mode (“S”) the bracketing settings are disabled (you are setting the shutter speed in this mode, so you cannot override this parameter).
- Be sure to set at least 3 frames (“3F” is shown in the upper display) in the bracketing settings. When “1F” is displayed, means bracketing is disabled.
- Be sure to set at least one EV step increment (the lower display should be different than “0.0”). If the increment is “0.5”, you can set it to “0.5”, “1.0”, “1.5”, etc.
- Check the number of frames to be bracketed at the lower exposure meter display. The red mark denotes the central frame, whereas the white marks denote the bracketed frames (darker/brighter). If you see only one red mark, that means that bracketing is disabled (see points 2 and 3).
- Also, check that there is space for the bracketed frames to be performed. That is: if your camera have an exposure compensation range of [−2, +2], in 0.5 steps, and you have set the exposure compensation to −1, for instance, you have set the BRK step to “2.0” (the maximum), and you try to change “1F” to “3F”, the resulting compensation would be −3, −1 (the current EV compensation) and +1, and of course, your camera negative EV compensation reach only −2, so the −3 compensation is out of range, that’s why Camera FV-5 won’t let you to change to “3F” in that situation (you will need to change EV to 0 to bracket 3 frames with “2.0” step).
