The D750 is equipped with the Multiple Exposure function, which lets you record two or more exposures into a single image. This provides another outlet for you to express your artistic side, by overlaying multiple RAW images to create interesting images. In this article, I shall provide a brief introduction to the function as well as provide some shooting ideas from a professional photographer’s perspective. (Reported by: Koji Ueda)
I took a multiple exposure of an old castle and the moon. The 1st exposure was of scenery containing only an old castle, taken using a wide-angle lens; the moon was not captured in this cut. For the 2nd exposure, I captured a large, close up shot of the moon using a telephoto lens. By combining it with the 1st exposure, I was able to create a scene containing both the castle and moon. On the D750, the RAW image files are used for image overlay in Multiple Exposures, so you can obtain an image that is rich in gradations.
In the photo shooting menu, select "Multiple Exposure".
For the multiple exposure mode, select "On (single photo)" or "On (series). If you select "On (single photo)", after completing one multiple exposure, the camera will reset to the normal shooting mode.
To take a series of multiple exposures, select "On (series)". If you use live view while multiple exposure mode is on, the camera will automatically reset multiple exposure mode to "Off".
Select the number of shots to be combined. You can combine two or three exposures into a single photograph.
If you select “ON” for Auto gain, the gain will be automatically adjusted according to the number of exposures recorded. As the gain for each exposure is adjusted using "1/number of exposures", if you are overlaying 3 exposures, the gain will be 1/3 for the shoot. On the other hand, setting the Auto gain to “OFF” is one way to obtain bright images in dark locations.
Auto gain ON
Auto gain OFF
If Auto gain is set to ON, the gain of the exposure is adjusted automatically, while if set to OFF, images may be overexposed. In situations where you want to obtain a brighter image of your multiple exposure, depending on the nature of the image you are creating, disabling auto gain might be an effective measure.
What kind of works can a professional photographer actually produce in street photography using the Multiple Exposure function? Here I will introduce three photographic effects that you can try out.
Aperture-priority Auto (f/3.5, 1/400 sec)/ ISO 100/ WB: Direct sunlight
One typical way of using multiple exposures would be with the soft focus effect. During the day when the light is harsh, it is difficult to depict the soft texture of flowers, so a soft filter effect is often used to create a dreamy image. However, if you use multiple exposure, you can obtain the same kind of effect even without a filter. For the first exposure, focus and shoot normally. Then, for the second exposure, use manual focus to greatly defocus the image. By combining the 2 shots, you can create a soft appearance just as in the example shot. You can try out this technique when photographing flowers and decorative lights.
Aperture-priority Auto (f/4, 1/320 sec)/ ISO 6400/ WB: Auto
Decorative lights are great for creating multiple exposures. When shooting illuminations, do not focus on the light source. Instead, use manual focus to slightly blur it out and create bokeh circles. The size of the bokeh circles differs greatly depending on the focus, so experiment around to get an idea of the variety of bokeh circles you can get from the decorative lights. The photo in this example combines bokeh circles with a fish in an aquarium, but you can also use this technique for subjects such as nightscapes and flowers.
Shutter-priority Auto (f/4, 1/2000 sec)/ ISO 220/ WB: Direct sunlight
The Multiple Exposure function is of course useful for building fantasy worlds, but it is also a great technique for combining closely related subjects like a surfer and palm tree, as in the example photo. A photo of the surfer alone might not have conveyed the sense of being on a tropical island, but combining it with an exposure of a palm tree did the trick. Try using the same technique—it’s a good way of showcasing a particular theme!
