Visitamos el photocall durante el concurso de cosplay.

Visitamos is the 1st person plural form of visitar, so it means we visit or we visited.

In this sentence, it is most naturally understood as we visited because the whole sentence sounds like a completed past event.

A useful thing to remember:

• visitamos can mean we visit (present)
• visitamos can also mean we visited (preterite)

Spanish sometimes uses the same form for both, so the context tells you which meaning is intended.

This happens with many -ar verbs in Spanish.

For visitar:

• Present: visitamos
• Preterite: visitamos

So the spelling is the same in both tenses for nosotros.

You usually tell the difference from context:

• Todos los años visitamos el evento. = We visit the event every year.
• Ayer visitamos el evento. = We visited the event yesterday.

In your sentence, durante el concurso suggests a specific event, so the past reading is very likely.

Spanish often uses a definite article where English might not.

Here, el photocall means the photocall / the photo area at the event. The article makes it sound like a specific, known place.

Compare:

• Visitamos el photocall. = We visited the photocall.
• Había un photocall. = There was a photocall.

So the article is there because the speaker is referring to a particular one.

Photocall is a borrowed word, and in Spanish borrowed nouns are often treated as masculine by default, especially when there is no long-established gender pattern forcing them to be feminine.

So in Spain, el photocall is the usual form.

This is something you often just have to learn with the noun:

• el cosplay (sometimes used)
• el email
• el photocall

In Spain, photocall is a very common event word. It usually means the area or backdrop where people stop to have photos taken, often at conventions, premieres, fairs, or parties.

So it is not exactly the same as a photo booth.

More specifically:

• photocall = a designated photo area, often with a branded background
• cabina de fotos or fotomatón = a photo booth machine

So this sentence is talking about going to that event photo area, not necessarily using a booth.

Durante means during.

It is used before a noun phrase, not before a fully conjugated verb:

• durante el concurso = during the contest
• durante la película = during the film

So durante el concurso de cosplay means during the cosplay contest.

If you wanted to say while and follow it with a verb, you would normally use mientras instead:

• Mientras veíamos el concurso... = While we were watching the contest...

The structure noun + de + noun is very common in Spanish.

Here:

• concurso = contest
• de cosplay = of cosplay / cosplay-related

So concurso de cosplay means cosplay contest.

Spanish often uses de where English uses one noun directly before another:

• tienda de ropa = clothing shop
• concurso de fotografía = photography contest
• evento de anime = anime event

Because cosplay is being used in a general, classifying way after de.

In Spanish, after de, a noun often appears without an article when it describes the type of thing:

• concurso de cosplay
• profesor de español
• tienda de videojuegos

You could use el cosplay in other contexts when you mean the activity or concept itself:

• El cosplay es muy popular.

But in concurso de cosplay, no article is needed.

Yes. Spanish word order is flexible, especially with time expressions.

These are both natural:

• Visitamos el photocall durante el concurso de cosplay.
• Durante el concurso de cosplay, visitamos el photocall.

The meaning stays basically the same. The second version puts more emphasis on when it happened.

Yes, that would also be natural, but it is slightly different.

• Visitamos el photocall focuses on visiting the photo area as a place or attraction.
• Fuimos al photocall simply means we went to the photocall.

So:

• fuimos a = emphasizes movement to a place
• visitamos = emphasizes the visit itself

Both can work, but visitamos may sound a bit more event-oriented, as if the photocall was one of the things you checked out.

It is pronounced with the stress on ta:

vi-si-TA-mos

In standard Spain pronunciation, the v sounds like a soft Spanish b, not like the English v.

A rough guide:

• visitamos ≈ bee-see-TAH-mos

The important stress point is:

• visiTAmos

Yes, it sounds natural, especially in the context of conventions, fairs, or pop-culture events in Spain.

A few reasons it sounds natural:

• photocall is widely used in Spain for event photo areas
• concurso de cosplay is a normal way to say cosplay contest
• durante fits well for during

So overall, it is a very plausible sentence for talking about a convention or similar event.
