What causes leaning verticals?

Pointing the camera up or down rather than level with the middle of the subject. It is normal optics and entirely avoidable.

Why does it matter beyond looks?

Because it distorts the product shape. A bottle appears narrower at the neck, a box appears trapezoidal, and a wrapped label appears to warp.

Can any photo be corrected?

Only up to a point. Squaring the frame stretches pixels, so a severely angled original softens visibly and is better reshot level.

Does this apply to phone photos?

Especially. Wide phone lenses exaggerate perspective, which is why casual product shots lean more than people expect.

Should I correct rotation too?

Yes. A slightly off-level line is conspicuous in a grid of otherwise square images, even when nothing else is wrong.

What should I check afterwards?

Label text first. Warped packaging text reads as poor production and is the most sensitive area to distortion.

Is it better to prevent or correct?

Prevent. Shooting level with the middle of the product avoids the pixel stretching that correction requires.

Why this is worth getting right

Keystone distortion is the effect that makes a tall product look like it is falling backwards, and it happens whenever the camera is not level with the middle of the subject — point up at a bottle and the sides converge toward the top, point down and they splay. It is entirely normal optics and entirely avoidable, and it is also one of the clearest signals separating a snapshot from a product photograph, because catalogue imagery has square verticals and amateur imagery does not. The reason it matters commercially is that converging verticals distort the shape of the thing being sold: a bottle appears narrower at the neck than it is, a box appears trapezoidal, and a label wrapped around a cylinder appears to warp. Correcting perspective straightens those edges and restores the honest proportion, which is the point rather than a cosmetic tidy. There is a limit worth knowing, since correction stretches pixels to square the frame and an extreme correction visibly softens the top or bottom of an image, so a severely angled original cannot be fully rescued and reshooting level is better. Rotation matters alongside it, because a horizon or shelf line even slightly off level is noticeable in a grid of otherwise square images. Text on packaging is the most sensitive area, as warped label text reads as poor production even when the product is fine.

Tips that actually help

Shoot level with the middle of the product where you can, since preventing keystone is far better than correcting it.
Correct verticals rather than accepting them, because converging edges distort the actual shape of what you are selling.
Watch for softening at the top or bottom after a large correction, as squaring the frame stretches pixels.
Level rotation as well as perspective, since a slightly tilted line is obvious in a grid of otherwise square images.
Check label text after correction, because warped packaging text reads as poor production even when the product is fine.

Who uses this

Tall products: Bottles, tubs and packaging where camera angle produces the most visible convergence.
Furniture and large items: Objects photographed from close range where distortion is unavoidable in camera.
Phone photography: Wide phone lenses exaggerate perspective, which is why casual product shots lean so visibly.
Catalogue consistency: Grids where one tilted image is conspicuous among square ones.
