请帮我看看这句话的大致意思
Applicants are required to submit a portfolio that includes samples of art or design work,freehand drawings,two- or three-dimensional work in any media,or written material.You should choose the presentation format — typically a folder with slides or photographic reproductions — that you feel is most appropriate for the work.
前面一句是内容要求,后面一句是提交形式,请问他的意思是不是说可以自己选择一种作品集的提交形式.
最后一句里 photographic reproductions typically 是什么意思（在句子里的意思，字典翻译带入看不太明白，是“比如”还是说只能限定slides 和 photographic reproductions 这两种形式？）
