  2. Focus stacking - Wikipedia

    en.wikipedia.org/wiki/Focus_stacking

    Focus stacking – also called focal plane merging, z-stacking, [1] or focus blending – is a digital image processing technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images. [2] [3] Focus stacking can be used in any ...

  3. Photomontage - Wikipedia

    en.wikipedia.org/wiki/Photomontage

    Other methods for combining images are also called photomontage, such as Victorian "combination printing", the printing of more than one negative on a single piece of printing paper (e.g. O. G. Rejlander, 1857), front-projection and computer montage techniques. Much as a collage is composed of multiple facets, artists also combine montage ...

  4. Blend modes - Wikipedia

    en.wikipedia.org/wiki/Blend_modes

    Dodge and burn change the lightness of the pictures, inspired by the dodging and burning performed in a darkroom. Dodging lightens an image, while burning darkens it. Dodging the image is the same as burning its negative (and vice versa). Dodge modes: The Screen blend mode inverts both layers, multiplies them, and then inverts that result.

  5. Alpha compositing - Wikipedia

    en.wikipedia.org/wiki/Alpha_compositing

    With the existence of an alpha channel, it is possible to express compositing image operations using a compositing algebra. For example, given two images A and B, the most common compositing operation is to combine the images so that A appears in the foreground and B appears in the background. This can be expressed as A over B.

  6. Image stitching - Wikipedia

    en.wikipedia.org/wiki/Image_stitching

    Two images stitched together. The photo on the right is distorted slightly so that it matches up with the one on the left. Image stitching or photo stitching is the process of combining multiple photographic images with overlapping fields of view to produce a segmented panorama or high-resolution image.

  7. Layers (digital image editing) - Wikipedia

    en.wikipedia.org/wiki/Layers_(digital_image_editing)

    In the program, layers can be stacked, merged, or defined when creating a digital image. Layers can be partially obscured allowing portions of images within a layer to be hidden or shown in a translucent manner within another image. Layers can also be used to combine two or more images into a single digital image.

  8. 3D reconstruction from multiple images - Wikipedia

    en.wikipedia.org/wiki/3D_Reconstruction_from...

    The correspondence problem, finding matches between two images so the position of the matched elements can then be triangulated in 3D space is the key issue here. Once you have the multiple depth maps you have to combine them to create a final mesh by calculating depth and projecting out of the camera – registration. Camera calibration will ...

  9. Multiple exposure - Wikipedia

    en.wikipedia.org/wiki/Multiple_exposure

    A multi-exposure composite image of the October 2004 lunar eclipse taken from Hayward, California. In photography and cinematography, a multiple exposure is the superimposition of two or more exposures to create a single image, and double exposure has a corresponding meaning in respect of two images.
