Questions & Answers about Analisámos a nitidez das fotografias, três das quais não selecionámos.
Why do we use das quais here instead of the simpler relative pronoun que?
Because of the partitive structure "three of which". When you have a quantifier like três followed by the preposition de, you cannot use the simple relative pronoun que. You must use the appropriate form of o qual (in this case, das quais) to explicitly link back to the group you are dividing.
What determines whether we use dos quais or das quais in this sentence?
The relative pronoun must agree in gender and number with the noun it refers back to. Here, it refers to as fotografias (feminine plural), so it becomes das quais (a contraction of de + as + quais). The quantifier três doesn't change this, as it is just counting the feminine items.
Why is there an accent on the "a" in Analisámos and selecionámos?
In European Portuguese, the acute accent on the -ámos ending indicates that these verbs are in the past tense (pretérito perfeito). It also tells you to pronounce the "a" with an open sound. Without the accent, analisamos and selecionamos would be present tense verbs, pronounced with a more closed "a" sound.
I haven't seen the word nitidez before. Is that the standard word for photo sharpness?
