Copyright and ownership question

[triptych]

Hi,

I've been asked by a friend to do a swimsuit shoot for her, she will be the model in them. She only wants me to take the photo's of her, she will be doing any post processing of them, as she wants the photo's to reflect her style which is confusing to me as I'd be the photographer so really it'd be my style so im not sure why she wants them to reflect her style?

She will be putting the photo's on her blog, and she will allow me to use 3 images for me to edit and publish as I like and as the images would be owned be her, I need to ask for written consent to use them.

Now this could be perfectly normal but just wanted to check before I sign anything as im really new to all this.

Thanks
