Digitalizamos y preservamos el álbum fotográfico.

Digitalizamos is the first person plural form of digitalizar, so it means we digitise / we digitize.

In this sentence, it can grammatically be either:

• present tense: we digitise / we are digitising
• preterite: we digitised

That is normal for many -ar verbs in Spanish: the nosotros form looks the same in the present and the preterite. The context tells you which meaning is intended.

The same is true of preservamos.

Spanish often omits subject pronouns because the verb ending already tells you who the subject is.

So:

• Digitalizamos y preservamos... already clearly means
• We digitise and preserve... or We digitised and preserved...

Adding nosotros is possible, but it is usually unnecessary unless you want emphasis or contrast:

• Nosotros digitalizamos y preservamos el álbum fotográfico. This would sound more like We are the ones who digitise and preserve the photographic album.

Y means and. It links the two actions:

• digitalizamos
• preservamos

Both verbs share the same subject and the same object, so Spanish does not need to repeat anything:

• Digitalizamos y preservamos el álbum fotográfico.

Spanish sometimes changes y to e, but only before words that begin with an i sound:

• padre e hijo

Here, the next word is preservamos, so y is correct.

Because both verbs act on the same direct object:

• el álbum fotográfico

So Spanish, like English, can use the object once after both verbs:

• Digitalizamos y preservamos el álbum fotográfico.

You could repeat the object, but it would usually sound unnecessarily repetitive:

• Digitalizamos el álbum fotográfico y preservamos el álbum fotográfico.

Álbum is a masculine noun, so it takes el:

• el álbum

Its grammatical gender must simply be learned. The ending does not always tell you the gender, especially with words of foreign origin or less common endings.

So:

• el álbum
• el álbum fotográfico

Its plural is:

• los álbumes

Álbum has a written accent because, without it, Spanish stress rules would place the stress differently.

The stress is on the first syllable:

• ÁL-bum

The accent mark shows that clearly.

This is especially useful because álbum is not a native-looking Spanish word pattern, so the accent helps signal the correct pronunciation.

In Spanish, most adjectives normally come after the noun.

So:

• álbum fotográfico = photographic album / photo album

Also, the adjective must agree with the noun:

• álbum is masculine singular
• so the adjective is fotográfico masculine singular too

Compare:

• el álbum fotográfico
• la colección fotográfica
• los archivos fotográficos

Yes. Álbum de fotos is very common and natural.

Both are correct, but they feel slightly different:

• álbum fotográfico can sound a bit more formal or descriptive
• álbum de fotos is very common in everyday speech

So these are both fine:

• Digitalizamos y preservamos el álbum fotográfico.
• Digitalizamos y preservamos el álbum de fotos.

Not exactly, though they are close.

Preservar often suggests:

• protecting something
• keeping it safe
• preventing damage or loss

Conservar often suggests:

• keeping something in good condition
• maintaining it
• not letting it disappear

In a sentence about archives, heritage, or old photographs, preservar sounds very natural because it suggests careful protection over time.

A Spain pronunciation would be approximately:

dee-hee-ta-lee-THA-mos ee preh-sehr-VA-mos el AL-boom fo-to-GRA-fee-ko

A few useful pronunciation points for Spain:

• gi in digitalizamos sounds like a strong throaty h sound
• z in digitalizamos sounds like th in thin
• y here sounds like ee
• álbum is stressed on the first syllable
• fotográfico is stressed on grá

So the main stressed parts are:

• digitaliZAmos
• preserVAmos
• Álbum
• fotográFIco? Actually no: fotoGRÁfico

By form alone, it could be either.

Both verbs:

• digitalizamos
• preservamos

can mean either:

• we digitise / preserve or
• we digitised / preserved

This happens because the nosotros form is identical in the present and preterite for regular -ar verbs.

Context decides the meaning. For example:

• Cada año digitalizamos y preservamos el álbum fotográfico. → present / habitual
• Ayer digitalizamos y preservamos el álbum fotográfico. → past

Because Spanish does not need to repeat the object when two verbs share it.

English also does this:

• We digitised and preserved the photographic album.

You do not have to say:

• We digitised the photographic album and preserved it.

Spanish works the same way here:

• Digitalizamos y preservamos el álbum fotográfico.

If you wanted, you could restructure it with a pronoun, but it would be a different sentence:

• Digitalizamos el álbum fotográfico y lo preservamos.

That is correct, but less compact.
