2 Take a shot.  The HDR mode cannot be set if you use any of the following functions: AEB, white balance bracketing, Multi Shot Noise Reduction, multiple exposures, flash exposure, remote bulb shooting, or movie shooting.  HDR shooting of a moving subject is not recommended because the movement of the subject will appear as afterimages in the merged image. HDR shooting is recommended for still subjects.  In HDR shooting, 3 images are captured with different shutter speeds set automatically. Therefore, even in Tv and M shooting modes, the shutter speed will be shifted based on the shutter speed set.  To prevent camera shake, the ISO speed may be set higher than usual.  Auto image alignment may not work properly with repetitive patterns (lattice, stripes, etc.) or flat, single-tone images.  The color gradation of the sky or white walls may not be reproduced correctly. Irregular colors or noise may appear.  With HDR shooting, the three images will be merged after you take a picture. Therefore, it will take a longer time to record the HDR image than with normal shooting. During the merging of the images, "BUSY" will be displayed on the camera and you cannot take another picture until the merging is completed. Introduction Contents  Using a tripod is recommended. For handheld shooting, using a fast shutter speed is recommended.  If [Auto Image Align] is set to [Enable] and the HDR picture is shot handheld, the edges of the photos will be cropped, lowering the resolution slightly. Also, if the images cannot be aligned properly due to camera shake, etc., auto image alignment may not take effect. Note that when shooting with excessively bright or dark exposure settings, auto image alignment may not work properly.  If you perform handheld HDR shooting while [Auto Image Align] is set to [Disable], the 3 images may not be properly aligned and the HDR effect may be minimal.  HDR shooting under fluorescent or LED lighting may result in unnatural color reproduction of the illuminated areas.  In HDR mode, the options dimmed in the menu cannot be set. Note that when you set HDR mode, for Auto Lighting Optimizer, highlight tone priority, and exposure simulation, [Disable] will be applied for shooting. 1 Downloading Images 2Camera Settings 3Remote Shooting 4 Preferences Reference Index 36
