Notice that we are forced here to change from anyone to everyone when using subject-predicate expansion because the result of retaining anyone would be awkward at best. In general, although it is not impossible for anyone to serve as the subject of a sentence (see f below), it is best to avoid using it as the subject of sentence in expanded form.

No picture pleased anyone except photographers.

All people except photographers are such that (no picture pleased them)

[or: Everyone who is not a photographer is such that (no picture pleased him or her)]

(∀x: x is a person ∧ ¬ x is a photographer) no picture pleased x

(∀x: Px ∧ ¬ Hx) no picture is such that (it pleased x)

(∀x: Px ∧ ¬ Hx) (∀y: y is a picture) ¬ y pleased x

C: [ _ is a picture]; H: [ _ is a photographer]; L: [ _ pleased _ ]; P: [ _ is a person]

The phrase all people is used in the first restatement so that it agrees in number with except photographers. It has the disadvantage that no picture pleased them might be misunderstood to say that no picture pleased them all. (That would be a misunderstanding because them used in the context them all would need a subject not already containing all—something like people other than photographers—as its antecedent.) The alternative using everyone who isn’t a photographer instead of all people except photographers is designed to avoid this misunderstanding. In general, it is best to choose a singular subject when using subject-predicate expansion.
