kamera no iti wo kaemasita.

A natural breakdown is:

• カメラ = camera
• の = links one noun to another, often like of or 's
• 位置 = position
• を = marks the direct object
• 変えました = changed

So the structure is basically:

camera + of + position + object marker + changed

In more natural English order, that becomes changed the camera's position or changed the position of the camera.

の connects nouns. Here it shows that 位置 belongs to or is associated with カメラ.

So:

• カメラの位置 = the camera's position
• literally, position of the camera

This is one of the most common uses of の in Japanese: noun + の + noun.

を marks the direct object of the verb.

In this sentence, the thing being changed is 位置:

• 位置を変えました = changed the position

So even though English may focus on the camera, Japanese grammar treats position as the object of change.

This is a very common question because 変える and 変わる are related but different:

• 変える = to change something
• 変わる = to change, to be changed

So:

• カメラの位置を変えました = I/they changed the camera's position
  
  • someone actively changed it
• カメラの位置が変わりました = the camera's position changed
  
  • it changed, without focusing on who did it

Here, 変えました is used because the sentence describes an action done to the position.

変えました is the polite past affirmative form of 変える.

Breakdown:

• dictionary form: 変える
• polite non-past: 変えます
• polite past: 変えました

So it means changed in a polite style.

Japanese often leaves out the subject when it is clear from context.

So カメラの位置を変えました could mean:

• I changed the camera's position
• We changed the camera's position
• They changed the camera's position

The exact subject depends on the situation. This is very normal in Japanese.

Not necessarily. A sentence can be complete without は.

For example:

• カメラの位置を変えました。 = Changed the camera's position.
• カメラの位置は変えました。 = As for the camera's position, I changed it.

Adding は changes the emphasis or topic. Without it, the sentence is a straightforward statement of an action.

カメラ is a loanword, originally from a foreign language, so it is written in katakana.

Katakana is commonly used for:

• foreign loanwords
• onomatopoeia
• emphasis
• some technical terms

Since camera is a borrowed word, カメラ is the normal spelling.

They are similar, but not exactly the same.

• 位置 = position, location in a more precise or spatial sense
• 場所 = place, spot, location in a broader everyday sense

In this sentence, 位置 fits well because it refers to where the camera is positioned. It sounds more exact than 場所.

For example:

• カメラの位置 = the camera's position
• カメラの場所 = the place where the camera is

Sometimes both are possible, but 位置 is especially natural when talking about adjusting placement.

The basic order here is very natural:

• カメラの位置を変えました

Japanese usually puts the verb at the end, so that part stays important. The noun phrase before it can sometimes be rearranged for emphasis, but this sentence is the standard and easiest form.

For a learner, it is best to think of the pattern as:

[thing being changed] を [verb]

Here, the thing being changed is カメラの位置.

Normally, Japanese is written without spaces:

• カメラの位置を変えました。

Spaces are often added in teaching materials to help beginners see the parts more clearly. They are not usually used in standard Japanese writing.

The plain past form is:

• カメラの位置を変えた。

Compare:

• 変えました = polite
• 変えた = plain/informal

Both mean changed, but 変えました is more suitable in polite conversation or neutral written explanations.

Yes, depending on context, it can sound very close to moved the camera, but literally it is changed the camera's position.

That slight difference matters:

• カメラを動かしました focuses more directly on moving the camera itself
• カメラの位置を変えました focuses on changing where the camera is placed

In many real situations, the English translation moved the camera would be perfectly natural.
