How to use multiple exposures for mobile phones?

Lead: Multi-exposure is a common creative technique in our photographic creation, which combines multiple independent exposures into one photo. This technology and visual effect are not only used in artistic photography, but also in many commercial photography.

But the mobile phone only simulates the effect of multiple exposures, not the real re-exposure. Photographers need to take two (or more) photos with their mobile phones, and then use the mobile phone photography APP for post-synthesis. The two photos superimposed by re-exposure are the background image and the foreground image, so it is necessary to pay special attention to the control of the dark part of the background image, because the image of the foreground image will be filled in the dark part of the background image after re-exposure and superposition of the two photos.

Take the works we shared this time as an example. The synthetic background image is the outline of Gao Fancha's head, and the foreground image is the Chicago complex:

Foreground map

My mobile phone uses Union to post-superimpose the two pictures, and the high-rise buildings in the foreground are filled in the silhouette of the head. In order to avoid the picture being too messy and complicated, I suggest to use some silhouette images with clear outline and Gao Fancha as the re-exposure background image, while the freedom of photo selection for the foreground image is relatively greater. Of course, the choice of re-exposed photos depends entirely on the individual's creative needs and intentions. That is, using some complicated and messy pictures for re-exposure, if superimposed properly, can also play new ideas.

Union is a small tool specially used for multiple exposures. In addition to exposing two photos on top of each other, it also has a simple masking tool that can erase unnecessary parts of the layer. I often use it with Mextures and VSCO Cam, and the effect is not bad. Youlian sells 12 yuan in Apple App Store.

Mextures

Mextures can be used as an auxiliary post-processing tool, and its biggest feature is that it can add texture and texture to photos, such as adding dust to old photos to make them look like old film scans. Mextures is sold in Apple App Store 12 yuan.

Specific steps:

0 1 picture overlay

Open Union, import portrait silhouette to the background layer, and then import Chicago architecture photos to the foreground layer. Select the overlay mode in the foreground layer interface as? Supplement? That is, the image of the building in the foreground image is filled into the portrait black silhouette.

02 details adjustment

Continue to adjust the details in the foreground layer interface of Union. In order to make the image of the building clearer in the avatar display, you can set the layer to be transparent. Opaque? Set it to 60%. For black and white effects, the color saturation can be set to 100%. If you don't adjust, keep the color and export the picture after adjustment.

03 increase texture

Open another post-application, Mextures, and import the newly-exposed picture. In order to add some texture to the photo, you can choose gravel and particles in the texture. Dust removal? , can increase the effect of old photos after scanning, and output the saved photos after adjustment to complete the work.
