הוא לא רוצה לראות את עצמו בתמונה.

Yes, Hebrew can often leave out subject pronouns because the verb already shows person, gender, and number. So רוצה לראות את עצמו בתמונה can still be understood as He wants to see himself in the picture if the context is clear.

However, הוא is often included:

• for clarity,
• for emphasis,
• or when starting a new sentence/topic.

So הוא לא רוצה לראות את עצמו בתמונה is completely natural.

In Hebrew, negation is usually made with לא placed before the verb or predicate.

So:

• רוצה = wants
• לא רוצה = does not want / doesn’t want

Hebrew does not use a helping verb like English do/does here.

רוצה is the present-tense masculine singular form of the verb לרצות = to want.

Because the subject is הוא = he, the verb must match masculine singular.

Compare:

• הוא רוצה = he wants
• היא רוצה = she wants
• הם רוצים = they (masculine/mixed) want
• הן רוצות = they (feminine) want

In the singular present tense, masculine and feminine are different in some verbs, but here:

• masculine singular: רוצה
• feminine singular: רוצה They are spelled the same, though pronunciation may differ slightly in careful speech.

לראות is the infinitive to see.

Hebrew often uses the pattern:

• רוצה + infinitive
• literally: wants to see

So:

• רוצה לראות = wants to see

This is very similar to English.

This את is the direct object marker. It appears before a definite direct object.

In this sentence, עצמו = himself, which is definite/specific, so Hebrew uses את before it:

• לראות את עצמו = to see himself

This את does not mean you here. That is a different word, even though it is written the same way without vowels.

Hebrew often forms reflexive meanings with עצם plus a possessive ending.

Here:

• עצמו = himself
  literally something like his self

So:

• את עצמו = himself as the direct object

Other forms include:

• עצמי = myself
• עצמך = yourself (masculine singular)
• עצמך = yourself (feminine singular, same spelling without vowels)
• עצמה = herself
• עצמנו = ourselves
• עצמם = themselves (masculine/mixed)
• עצמן = themselves (feminine)

For many verbs, Hebrew expresses self-actions with את + עצמי/עצמו/etc.

So:

• He sees himself → הוא רואה את עצמו
• He wants to see himself → הוא רוצה לראות את עצמו

Some Hebrew verbs do have built-in reflexive meanings in certain verb patterns, but to see oneself is normally expressed with לראות את עצמו, not with a special reflexive form.

בתמונה means in the picture / in the photo.

It is made of:

• ב־ = in
• התמונה = the picture / the photo

When ב joins ה, they contract:

• ב + התמונה → בתמונה

So this is a very common Hebrew combination.

It can mean either picture or photo, depending on context.

So בתמונה could mean:

• in the picture
• in the photo

If the context is about a photograph, English will often translate it as photo. If the context is broader, picture may be better.

The sentence follows a very common Hebrew order:

• הוא = subject
• לא רוצה = negated verb phrase
• לראות את עצמו = infinitive phrase + object
• בתמונה = prepositional phrase

So literally it is:

• He not wants to-see himself in-the-picture

A natural English translation is:

• He doesn’t want to see himself in the picture.

You would change the pronoun and the reflexive form:

• היא לא רוצה לראות את עצמה בתמונה.
• She doesn’t want to see herself in the picture.

Notice:

• הוא → היא
• עצמו → עצמה

The form רוצה stays the same in spelling here.

Yes. You could say:

• לא רוצה לראות את עצמו בתמונה

This can mean He doesn’t want to see himself in the picture, as long as context makes the subject clear.

But if there is no context, keeping הוא is safer and clearer.

A common pronunciation is:

hu lo rotse lir’ot et atsmo batmuna

A rough breakdown:

• הוא = hu
• לא = lo
• רוצה = rotse
• לראות = lir’ot
• את = et
• עצמו = atsmo
• בתמונה = batmuna

In everyday speech, the rhythm is smooth and connected, especially around בתמונה.
