Ρύθμισε την εστίαση· η θολή εικόνα θα γίνει ευκρινής.

Ρύθμισε is the aorist imperative, 2nd person singular, of ρυθμίζω (to adjust / to set / to regulate).

Here it means Adjust! or Set!, said to one person.

Why the aorist imperative? In Greek, the aorist imperative often gives a command as one complete action:

• Ρύθμισε την εστίαση. = Adjust the focus.
• It suggests: do it once, get it done.

If you were speaking to more than one person, you would say:

• Ρυθμίστε την εστίαση.

Because εστίαση is the direct object of Ρύθμισε.

Greek articles change by case:

• η εστίαση = the focus as a subject
• την εστίαση = the focus as an object

So in:

• Ρύθμισε την εστίαση the thing being adjusted is the focus, so it must be in the accusative:
• την εστίαση

Here εστίαση means focus in the optical or camera sense.

So:

• Ρύθμισε την εστίαση = Adjust the focus

In other contexts, εστίαση can also mean focusing as a process, depending on the sentence.

The mark · is called the ano teleia in Greek.

It often works like an English:

• semicolon
• or sometimes a colon
• or a strong pause between related clauses

So:

• Ρύθμισε την εστίαση· η θολή εικόνα θα γίνει ευκρινής.

means something like:

• Adjust the focus; the blurry image will become sharp.

A very important Greek punctuation point for learners:

• the English semicolon ; is used in Greek as a question mark
• so Greek ; = ?
• while Greek · does the job of a semicolon-like pause

Because this is the subject of the verb θα γίνει.

Breakdown:

• η = the (feminine nominative singular)
• θολή = blurry / blurred
• εικόνα = image / picture

So:

• η θολή εικόνα = the blurry image

It is in the nominative because it is the thing that will become something.

θολή is the feminine singular nominative form of the adjective θολός (blurry, cloudy, blurred).

Greek adjectives agree with the noun they describe in:

• gender
• number
• case

Since εικόνα is:

• feminine
• singular
• nominative

the adjective must match it:

• θολή εικόνα

Compare:

• θολός φακός = blurry lens (masculine)
• θολή εικόνα = blurry image (feminine)
• θολό τοπίο = blurry landscape (neuter)

θα γίνει literally means will become.

It comes from γίνομαι, which means:

• to become
• to happen
• sometimes to be made / to be done, depending on context

Here:

• η θολή εικόνα θα γίνει ευκρινής = the blurry image will become sharp/clear

So the sentence is talking about a change of state:

• blurry → sharp

Because θα γίνει refers to a single completed change: the image will end up becoming clear.

In modern Greek, after θα, the verb form helps show aspect:

• θα γίνει = will become as a complete event
• θα γίνεται = will be becoming / will become repeatedly / habitually, depending on context

In this sentence, the idea is simple and result-focused:

• adjust the focus
• the image will become clear

So θα γίνει is the natural choice.

Modern Greek forms the future with θα plus a verb form based on the subjunctive system, not with a separate future tense ending like Ancient Greek or like English will + verb.

So:

• θα γίνει = will become

This is built from:

• θα
  • γίνει

You do not need to think of γίνει here as a standalone present-tense form. In this structure, it functions as part of the future expression.

This pattern is very common:

• θα δω = I will see
• θα πάω = I will go
• θα γράψει = he/she will write
• θα γίνει = it will become

Because ευκρινής is an adjective meaning clear, distinct, or sharp, and here it agrees with εικόνα.

This adjective belongs to a different adjective pattern from words like θολός.

Here the feminine nominative singular form is:

• ευκρινής

So:

• η εικόνα θα γίνει ευκρινής = the image will become sharp / clear

This adjective is especially common in more formal or technical language, such as optics, screens, print, or image quality.

Because after γίνει, ευκρινής is a predicate adjective describing the subject η εικόνα.

Since η εικόνα is:

• feminine
• singular
• nominative

the adjective stays in the matching nominative form:

• ευκρινής

A helpful comparison:

• Βλέπω την ευκρινή εικόνα. = I see the sharp image.
  Here ευκρινή is accusative because it directly modifies the object.
• Η εικόνα είναι ευκρινής. = The image is sharp.
  Here ευκρινής is nominative because it is a predicate adjective with the subject.

Your sentence follows the second pattern:

• η θολή εικόνα θα γίνει ευκρινής

They are similar, but not always identical.

• ευκρινής often means sharp, distinct, well-defined
• καθαρή often means clean, clear, and in some contexts not blurry or not noisy

For an image, both can sometimes work, but:

• ευκρινής εικόνα sounds more technical/precise
• καθαρή εικόνα sounds more general and very common

So in an optics or camera context, ευκρινής is a very good choice.

Yes. Greek word order is more flexible than English, because case endings and agreement already show the relationships between words.

The neutral order here is:

• Ρύθμισε την εστίαση· η θολή εικόνα θα γίνει ευκρινής.

But you could also say things like:

• Η θολή εικόνα θα γίνει ευκρινής, αν ρυθμίσεις την εστίαση.
• Την εστίαση ρύθμισε.
  This gives extra emphasis to the focus.

Even though word order can move, the original version sounds natural and straightforward.

A rough pronunciation guide is:

• Ρύθμισε ≈ REETH-mi-se
• την εστίαση ≈ teen es-TEE-a-see
• η θολή εικόνα ≈ ee tho-LEE ee-KO-na
• θα γίνει ευκρινής ≈ tha YEE-nee ef-kree-NEES

A few useful pronunciation notes:

• θ sounds like th in think
• γ before ι / ε often sounds like a soft y-like sound, so γίνει is close to YEE-nee
• stress matters a lot in Greek:
  • Ρύθμισε
  • εστίαση
  • θολή
  • εικόνα
  • ευκρινής

Yes, slightly.

The sentence is perfectly natural, but words like:

• ρύθμισε
• εστίαση
• ευκρινής

make it sound a bit instructional, technical, or device-related, as if from:

• a camera manual
• a phone screen prompt
• software instructions
• a troubleshooting guide

A more everyday version might use simpler wording depending on context, but this sentence is completely good Greek.
