Who writes about these tools usually earns from it

Almost every comparison in this category pays a commission. Not a scandal — the normal state — and it changes one thing about how to read them.

What is distorted is the shortlist

Not the judgement on a product, but which are considered at all. A headshot tool without an affiliate programme appears in no list, however good it is.

The second-order effect

Order often tracks commission rate. That is why ten independent articles show the same three names in the same sequence.

Where disclosure matters

A published affiliate programme is not a mark against a vendor. A concealed one is, because it turns a recommendation into something that looks like an assessment.

What none of it changes

What makes a portrait work: contrast between hair and background, a crop matched to the display size, frontal light. No commission structure alters the geometry.

How to use them anyway

Take the method: does the comparison say which source photographs it used? Does it show a failed run? Does it carry a date?

Three questions that work regardless of who profits from the click.
