Excuse me, is the principle of miniature artistic filter of digital camera the same as that of shifting axis photography?

No, the filter of digital camera adds fuzzy filters on the upper and lower sides of the photo to imitate the effect of shifting axis photography, which is different from the actual effect. Specifically, it is uniform blur, and the real blur of shift-axis photography is based on the focal length. For example, if there is a tall building in the photo, the digital filter may show that the upper and lower parts of the building are blurred, but when the axis is moved, the same focus range is clear, okay? It might be a little confusing.
