Guardamos la prueba fotográfica a efectos de presentar alegaciones.

Guardamos is the 1st person plural form of guardar, so it means we keep, we store, or we save.

In this sentence, it is in the present indicative:

• yo guardo
• tú guardas
• él/ella guarda
• nosotros/nosotras guardamos

Depending on context, guardamos can sound like:

• we keep
• we are keeping
• sometimes even we have kept in a practical translation, if the context is administrative

Here it most naturally means something like we keep/store the photographic evidence.

Spanish often uses the present tense in formal, administrative, or procedural language to describe what is done as part of a process.

So Guardamos la prueba fotográfica... may describe a current policy or action:

• We keep the photographic evidence...
• We retain the photographic evidence...

If the speaker wanted to emphasize a completed action, they might say:

• Hemos guardado la prueba fotográfica... = We have kept/saved the photographic evidence...
• Guardamos la prueba fotográfica ayer... = We kept/saved the photographic evidence yesterday

In official-style Spanish, the present often sounds natural even when English might choose a slightly different tense.

La prueba fotográfica literally means the photographic proof/evidence.

Here:

• prueba = proof, evidence
• fotográfica = photographic

In legal or administrative contexts, prueba often means evidence, not just proof in the everyday English sense.

So good English equivalents include:

• the photographic evidence
• the photographic proof
  with photographic evidence usually sounding more natural in legal English.

Both can exist, but prueba is especially common in legal and administrative Spanish when talking about evidence submitted or kept for a procedure.

Very roughly:

• prueba = evidence/proof, often in a more procedural or legal sense
• evidencia = evidence, but sometimes less standard in some legal-administrative varieties, or used in different contexts

In Spain, prueba fits very naturally in formal/legal language:

• aportar pruebas
• presentar pruebas
• prueba documental
• prueba fotográfica

So la prueba fotográfica sounds idiomatic and official.

A efectos de is a formal expression meaning something like:

• for the purpose of
• with a view to
• for the purposes of

So:

• a efectos de presentar alegaciones = for the purpose of submitting objections/representations

This is much more formal than simply saying para.

Compare:

• Guardamos la prueba fotográfica para presentar alegaciones.
  = simpler, more direct
• Guardamos la prueba fotográfica a efectos de presentar alegaciones.
  = more official, bureaucratic, legal-sounding

Yes, in terms of basic meaning, para would work:

• Guardamos la prueba fotográfica para presentar alegaciones.

This is grammatically correct and easier to understand.

However, the original sentence uses a efectos de because it sounds:

• more formal
• more administrative
• more legal/bureaucratic

So the difference is mainly register, not core meaning.

In Spain, alegaciones is a very common legal/administrative term. It usually means statements, objections, or representations made in response to an official process.

Depending on context, it may be translated as:

• objections
• representations
• submissions
• arguments
• statements in one’s defense

It does not usually mean casual spoken arguments. It belongs to formal procedure.

For example, if a person receives a fine or an administrative notice, they may presentar alegaciones to explain their position or challenge the decision.

Yes, presentar alegaciones is a very common formal collocation in Spanish, especially in Spain.

It literally means to submit objections/representations.

Common administrative combinations include:

• presentar alegaciones
• formular alegaciones
• interponer un recurso
• aportar pruebas

Even though presentar usually means to present, in this context it often translates better as:

• submit
• file

So presentar alegaciones is more like to file/submit objections than simply to present arguments.

In legal and administrative Spanish, alegaciones is very often used in the plural because a person usually submits a set of points, arguments, or objections.

So the plural sounds natural and standard:

• presentar alegaciones
• formular alegaciones

The singular alegación exists, but in this type of official phrase the plural is more common.

It is definitely formal, and it sounds like administrative or legal Spanish from Spain.

The clues are:

• a efectos de
• prueba fotográfica
• presentar alegaciones

In everyday speech, a Spanish speaker would probably say something simpler, for example:

• Guardamos las fotos por si tenemos que reclamar.
• Hemos guardado las fotos para poder presentar una reclamación.

So the original sentence is natural in official writing, but not very conversational.

The sentence uses la prueba fotográfica, which means the photographic evidence—so it refers to specific evidence already known in the context.

Compare:

• Guardamos la prueba fotográfica... = we keep the photographic evidence
• Guardamos una prueba fotográfica... = we keep a piece of photographic evidence

Using la suggests the speaker and listener already know which evidence is being referred to, or that it is being treated as a specific body of evidence in the case.

Yes. Even though prueba is singular, it can function like a collective or abstract noun meaning photographic evidence in general.

So it may refer to:

• one photograph
• several photographs
• a set of images used as evidence

That is why la prueba fotográfica often sounds broader than la foto or las fotos.

The meaning would stay essentially the same.

Compare:

• Guardamos la prueba fotográfica a efectos de presentar alegaciones.
• A efectos de presentar alegaciones, guardamos la prueba fotográfica.

The second version puts more emphasis on the purpose first:

• For the purpose of submitting objections, we keep the photographic evidence.

This kind of fronting is common in formal Spanish, especially in written or official language.
