Art(s), Should I use plural?

[ucul]

Should I use plural in this sentence or just singular?

I have a special interest in art(s).

Also which one is correct to saying this?

1. I have a special interest in scale model
2. I have a special interest in scale modeling

I have a special interest in art.
I have a special interest in the arts.

1. I have a special interest in scale models.
2. I have a special interest in scale modelling.

 

[ucul]

I have a special interest in art.
I have a special interest in the arts.

1. I have a special interest in scale models.
2. I have a special interest in scale modelling.

Sir, what is the difference between scale models and scale modeling ​in the above sentence?

 

[bhaisahab]

What do you think the difference might be?

 

[ucul]

What do you think the difference might be?

the one is using suffix (-ing) the other is not.

 

[bhaisahab]

the one is using suffix (-ing) the other is not.

Well yes, but there is a difference in meaning.

 

[ucul]

Well yes, but there is a difference in meaning.

I really don't know what it is. Could please explain it to me, Sir?

 

[MikeNewYork]

"Scale modeling" is the production of scale models.

 

[ucul]

"Scale modeling" is the production of scale models.

So is it correct if I say "I have a special interest in scale modeling"? Or should I say "My hobby is scale modeling"? Thanks for the previous explanation anyway.

 

[MikeNewYork]

Either of those would work.

 

[ucul]

Either of those would work.

One more question. If I have more than one interest is it OK to say: "I have a special interests in scale modeling and photography."​?

 

[MikeNewYork]

As written, you would have to delete the "a" before "special". I would prefer, "I have a special interest in both scale modeling and photography."
