היא עומדת לצלם את הגשר החדש, אבל שכחה את המצלמה בבית.

Yes, עומדת literally means is standing. But in Hebrew, עומד / עומדת + infinitive is also a very common structure meaning is about to ... or is just going to ....

So:

• היא עומדת = she is standing
• היא עומדת לצלם = she is about to photograph

This is an idiomatic grammatical pattern, not just a literal description of posture.

Because the subject is היא = she, which is feminine singular.

In the present tense, Hebrew verbs often look like adjectives and must agree with the subject in gender and number:

• הוא עומד = he is standing / he is about to
• היא עומדת = she is standing / she is about to

So עומדת matches the feminine subject היא.

לצלם is the infinitive form of the verb to photograph / to take a picture.

The prefix ל־ often marks the infinitive in Hebrew, similar to English to:

• לכתוב = to write
• לאכול = to eat
• לצלם = to photograph

So in עומדת לצלם, the second word is the action she is about to do.

את is the marker of a definite direct object. It usually has no separate English translation.

Hebrew uses את before a direct object when that object is definite, for example when it has ה־ (the) or a possessive meaning.

So:

• לצלם גשר = to photograph a bridge
• לצלם את הגשר = to photograph the bridge

In your sentence, הגשר החדש is definite (the new bridge), so את is required.

In Hebrew, adjectives usually come after the noun, unlike in English.

So:

• גשר חדש = a new bridge
• הגשר החדש = the new bridge

The basic order is:

noun + adjective

That is why bridge new is the Hebrew word order.

Because in Hebrew, when a noun is definite, the adjective describing it also has to be definite.

Compare:

• גשר חדש = a new bridge
• הגשר החדש = the new bridge

This is called definiteness agreement. If the noun has ה־, the adjective normally gets ה־ too.

Because the sentence describes two different time relationships:

• היא עומדת לצלם = she is about to photograph the bridge
• אבל שכחה את המצלמה בבית = but she forgot the camera at home

The forgetting happened earlier, and now the result affects the present situation. So the tense shift is natural:

• imminent action: about to photograph
• earlier completed action: forgot

Hebrew, like English, can mix these when the timeline requires it.

שכחה is the past tense, third person feminine singular form of לשכוח = to forget.

It matches the subject היא:

• הוא שכח = he forgot
• היא שכחה = she forgot

So the verb agrees with the feminine singular subject.

Because את is only used for a definite direct object.

In שכחה את המצלמה:

• המצלמה is the direct object of forgot
• it is definite (the camera)
• so את is used

But בבית is not a direct object at all. It is a prepositional phrase:

• ב־ = in / at
• בית = house / home

So there is no reason to use את there.

בבית here means at home or in the house/home, and Hebrew often uses this simple form when the meaning is general or obvious from context.

So:

• שכחה את המצלמה בבית = she forgot the camera at home

If you wanted to be more explicit, Hebrew could also say things like:

• בבית שלה = in her house / at her home

But in everyday Hebrew, בבית often naturally means at home without needing to spell out whose home it is.

Because ב־ indicates location, while ל־ usually indicates direction.

• בבית = in the house / at home
• לבית = to the house / homeward

Here the meaning is that the camera was left or forgotten at home, meaning its location is the home. So בבית is the correct choice.

Yes, often Hebrew can omit subject pronouns because the verb form already shows person, gender, and number.

For example, עומדת לצלם can already suggest she is about to photograph, especially in context.

But היא may be included for clarity, contrast, or because the sentence is being presented on its own. In a standalone example sentence, keeping היא makes the subject very clear.

In normal modern Hebrew, מצלמה means camera, and in most contexts it naturally refers to a photographic camera. It can also be used for other kinds of cameras depending on context, such as a video camera or surveillance camera.

In this sentence, because the verb is לצלם (to photograph), the meaning is clearly a camera used for taking pictures.
