Help with a presentation
 

Hi

Im going to make a presentation for my japanese class i attend to.
Its a beguinner class so i dont always have to speak japanese under the presentation.

Im going to give a presentation about studio ghibli. Really breif like 3-5 minutes.

And i have some questions.

If you show a picture of someone, like if i show a picture of my dad and say.
こちらは　わたしの　おとうさん　です。

Or dont that work on pictures of persons?

And i need some help with a sentence.

"Hi
Today im going to speak about studio Ghibli."

こんにちは
きょう　わたしは

And i need help with the "going to speak about studio Ghibli." part.

Thanks

Hi,

I'm Siana, I've learned Japanese 5 years. I may be wrong but for my you can say:
こちらは　わたしの　おとうさん　です。
when you show your Dad's picture. Or you can also use "そちら" If you're not just close the picture projection.

If you rather wanna be more specific you can also say "こちらは(そちらは)私のお父さんのしゃしんです。" (here is a picture of my father).

about the presentation of your subject you can say:
こんにしは
きょう　わたしはGhibli　studio について話しています。( I'm gonna talk about the Ghibli　studio.)

You are incorrect. お父さん is used to talk to your father or about someone else's father. For your own father, when talking to someone outside your family, you say 父 instead.

KyleGoetz is correct. You do not use 「おとうさん」 to refer to your father in a presentation or any kind of public speaking. If you do, you will sound like an 8-year-old kid. The kanji in Kylegoetz' post is read ちち. For "mother", it is 母（はは）.

Holding or pointing your finger to a photo, you can say:
「こちらがちちのしゃしんです。」
「これがちちのしゃしんです。」
Or simply,
「これがちちです。」

Native speakers would NOT use 「わたし」 in saying this becasue everyone knows whose father you are talking about. If you are required to use it by your teacher, then you are required. I just want you to know how Japanese is spoken by us native speakers.

Can you correct your 「こんにしは」? It is too basic a phrase for me to correct.

Same thing with 「わたし」. Your audience know who you are talking about.

「きょうはスタジオジブリについておはなしします。」

Do not use 「はなしています」as suggested by SianaRei.
