Kurs:Photoshop Einzellösungen/en/Vertical Stitching of Geometrically Clearly Defined Objects

This course addresses beginners. The editing steps are kept simple on purpose.

Initial Situation

Certain circumstances do not allow you to photograph an object from the necessary distance and so you take several photos slightly staggered:

The slightly different lighting situations can be ignored for now. It's clearly visible that the vertical lines significantly differ. But this is not a problem.

Automated Stiching

File -> Automate -> Photomerge... Layout stays set to Auto, set check mark to

Vignette Removal
Geometric Distortion Correction

and than click ok, result:

Amend Compilation

Use <Ctrl>+<E> to reduce the 4 single layers to one layer
Use <Ctrl>+<Shift>+<L> for auto color correction (Auto Levels)
Use Edit -> Transform -> Distort to correct the perspective distortion
the full image is cutted out along the visible borderlines
Use Edit -> Transform -> Warp to adjust the horizontal lines

Use guides to adjust the vertical lines correctly
distort upwards, the object would be too wide
the horizontals are adjusted by eye

Final Result

Not optimal but usable. The path and the bottom edge are still crooked and could be corrected - but not necessarily need to be.
