## DRO/Auto HDR

D-Range Optimizer
Auto HDR
Corrects the brightness or contrast.

1. Fn (DRO/Auto HDR) desired mode

| (Off) | Does not use [DRO/Auto HDR].
| (D-Range Opt.) | By dividing the image into small areas, the camera analyzes the contrast of light and shadow between the subject and the background, producing the image with the optimal brightness and gradation.
| (Auto HDR) | Shoots three images with different exposures, and then overlays the bright area of the under exposed image and the dark area of the over exposed image to create an image with rich gradation. One image with proper exposure and one overlaid image are recorded.

### D-Range Optimizer

1. Fn (DRO/Auto HDR) [D-Range Opt.]

1. Select the optimal level using / on the control wheel.

| (D-Range Optimizer: Auto) | Corrects the brightness automatically.
| (Level)* | Optimizes the gradations of a recorded image in each area of the image. Select the optimal level between Lv1 (weak) and Lv5 (strong).

* The Lv number that appears with the mark indicates the current setting value.
Notes

- When shooting with [D-Range Opt.], the image may be noisy. Select the proper level by checking the recorded image, especially when you enhance the effect.

### Auto HDR

1. Fn (DRO/Auto HDR) [Auto HDR]

1. Select the optimal level using / on the control wheel.

| (Auto HDR: Exposure Diff. Auto) | Corrects the exposure difference automatically.
| (Exposure Difference Level)* | Sets the exposure difference, based on the contrast of the subject. Select the optimal level between 1.0 EV (weak) and 6.0 EV (strong). For example, if you set the exposure value to 2.0EV, three images will be composed; –1.0EV, optimal exposure and +1.0EV images.

* The EV number that appears with the mark indicates the current setting value.
Notes

- Since the shutter is released three times for one shot, be careful about the following:

- Use this function when the subject is motionless or does not blink

- Do not recompose.

- You cannot use this function with RAW images.

- You cannot start the next shoot until the capture process is completed after you shoot.

- You may not obtain a desired effect depending on the luminance difference of a subject and the shooting conditions.

- When the flash is used, this function has little effect.

- When the contrast of the scene is low or when significant camera shake or subject blur has occurred, you may not obtain good HDR images. If the camera detects such situation, is indicated on the recorded image to inform you of this situation. Shoot again, as necessary, recomposing or paying attention to the blur.
