A záridő annyira hosszú, hogy a kép elmosódik.

Záridő is a photography term. It refers to the length of time the camera shutter stays open, so in English it is usually shutter speed or exposure time, depending on context.

It is a compound noun:

• zár = shutter, closing device
• idő = time

So it literally means something like shutter time.

Both A and a are the Hungarian definite article, meaning the.

• A záridő = the shutter speed / the exposure time
• a kép = the picture / the image

Hungarian has two forms of the definite article:

• a before most consonants
• az before vowels

Here, záridő begins with a consonant sound, so a/ A is used. The first one is capitalized only because it begins the sentence.

This is a very common Hungarian pattern meaning so ... that ...

Structure:

annyira + adjective/adverb + hogy + clause

In this sentence:

• annyira hosszú = so long
• hogy a kép elmosódik = that the image gets blurred

So the whole pattern means:

• so long that the picture blurs
• or more naturally, the exposure is so long that the image becomes blurred

This structure is very useful in Hungarian:

• Annyira fáradt vagyok, hogy nem tudok gondolkodni.
  I’m so tired that I can’t think.

Because annyira does not mean more. It means so or to such an extent.

So:

• hosszú = long
• annyira hosszú = so long

If you used hosszabb, that would mean longer, and the sentence would need a comparison.

So Hungarian, like English, says:

• so long that... not
• longer that...

Here hogy introduces the result clause: that.

So:

• A záridő annyira hosszú = The shutter speed is so long
• hogy a kép elmosódik = that the image gets blurred

In many contexts, hogy means that, but its exact translation depends on the structure. In this sentence, it is part of the fixed annyira ... hogy ... pattern.

Elmosódik is a verb meaning gets blurred, becomes blurry, or blurs.

It comes from mosódik, which has the idea of becoming washed out, smeared, or blurred, and the prefix el- often adds the sense of completion or a resulting change of state.

So elmosódik is not usually someone blurs it. It means the picture itself becomes blurred.

That is why it fits well here: the long exposure causes the image to blur.

Hungarian often uses the present tense for general truths, regular results, and technical facts, just like English can.

So this sentence means something like:

• If the exposure is this long, the image gets blurred
• The exposure is so long that the image becomes blurred

It is not necessarily talking about something happening right this second. It can describe a general consequence.

Yes, absolutely.

Both are natural:

• A záridő annyira hosszú, hogy a kép elmosódik.
• Annyira hosszú a záridő, hogy a kép elmosódik.

The second version puts stronger emphasis on annyira hosszú — so long.

Very roughly:

• A záridő annyira hosszú... = neutral statement
• Annyira hosszú a záridő... = stronger emphasis on how long it is

Hungarian word order is flexible and often used for emphasis.

In this sentence, hosszú is not directly attached to the noun inside a noun phrase. It is part of the predicate:

• A záridő ... hosszú = The shutter speed is long

So this is like English The exposure time is long, where the adjective also comes after the verb idea.

If Hungarian wanted to say the long exposure time as a noun phrase, the adjective would come before the noun:

• a hosszú záridő = the long exposure time

But here the sentence is not a hosszú záridő.... It is saying something about the shutter speed, so hosszú is functioning as the descriptive predicate.

All three can work depending on context.

• kép literally means picture or image
• In photography, it can often be understood as photo or image

In this sentence, because it is about camera settings, English speakers often say:

• the image becomes blurred
• the photo comes out blurry
• the picture is blurred

So image is often the most technical-sounding choice, while picture is very natural in everyday English.

A very natural translation would be:

• The shutter speed is so slow that the picture comes out blurry.
• The exposure is so long that the image gets blurred.

This is useful because Hungarian says hosszú = long, but in everyday photography English, people often talk about slow shutter speed rather than long shutter speed.

So the Hungarian sentence is grammatically straightforward, but the most natural English wording may shift slightly depending on style and context.
