About this app

■ Overview
This is a dedicated exposure bracketing camera that allows you to set specific ranges for Shutter Speed (SS) and ISO.
Ideal for HDR composition requiring high dynamic range, product ,nightscapes, and astrophotography.

【About Unlocked Mode】
Enabling "Unlock Limits" allows values (SS/ISO) beyond the device's official specifications. Values exceeding hardware limits are displayed in red. These may not reflect correctly or may cause the app to crash depending on the device.

■ How to Use
1. Set Focus, SS range, ISO range, and White Balance (WB), then press the shutter button.
2. To capture only one sequence, set the interval count to "1".
3. The preview screen does not reflect exposure settings. Adjust based on the actual captured images.

■ Key Features
- Exposure Display: Choose between standard camera values (e.g., 1/125s) and power-of-two values (e.g., 1/128s). *Exif data is recorded using the precise power-of-two values.
- Step Adjustment: SS and ISO increments can be set from 1EV down to 1/3EV.
- Self-Timer: 3, 5, 7, or 10 seconds (Press shutter button to cancel).
- Focus Zoom: Magnified preview for precise manual focusing.
- Interval Shooting: If the set interval is shorter than the bracketing sequence, it will shoot at the minimum possible interval.
- WB Adjustment: If colors appear incorrect, set to "AUTO" first then adjust, or switch the "WB Type" in the menu.
- Sound Effects: Can be toggled ON/OFF. *Note: The physical shutter sound may still play due to device restrictions.
- Unlocked Range: Expands SS (1/128,000s to 128s), ISO (6 to 204,800), and step increments down to 1/10EV.

■ Precautions
- Due to hardware limitations, WB changes may not apply on some devices.
- Using values outside official specs may result in unexpected exposure or app crashes. Please perform test shots in advance.
- SS and ISO values follow a specialized sequence based on theoretical ISO standards.
