How To Use ITunes To Remove Photos From IPhone 5s

My father has an iPhone 5s for work and he cannot remember the pass code that he set up on the phone when it was issued to him by his employer. He took pictures on the phone during a recent business trip and he would like to recover the photos, but he cannot remember the password and the display reads: iPhone disabled. Please try again in 15 minutes. He has tried several times to unlock the phone and it has not worked. Is there any way my father can recover the photos using iTunes or some other work around? Also, there is no business or personal Apple ID set up on the phone. His employer does not want any Apple ID or anything personal set up on the phones whatsoever.

iPhone 5s, iOS 7.1.2
