Digital zoom

[citation needed] Digital zooming may be enhanced by computationally expensive algorithms which sometimes involves artificial intelligence.

In cameras that save in a lossless format, resizing in post-production yields results equal or superior to digital zoom.

The benefits are reduced file sizes and the ability to calculate the zoom level from the image's dimensions, if not included in its meta data.

[citation needed] The intelligent zoom only uses the centre of the image sensor and does not interpolate the original resolution, so the resulting image quality is good in reduced resolution.

[7] Photographers can purposefully employ digital zoom for the characteristic low-fidelity appearance of the images it produces.

Zooming
Digital zoom has been used to create the middle photo from within the top photo. The image quality has been lost. No quality is lost however, with the lens zoomed-in optically for the bottom photo. Typically, the digital zoom is not available until the optical zoom has been exhausted.
