It certainly will help if the state doesn't have photo evidence of any injuries. If you haven't already done so, start looking around for a good lawyer to represent you. This obviously is a serious charge so you need to legal assistance ASAP. Best of luck!

Tedd is correct, you need to find a good criminal defense attorney and not discuss this case with anyone else or on a public site like this one.
My name is Stephen R. Cohen and have practiced since 1974. I practice in Los Angeles and Orange County, CA. These answers do not create an attorney client relationship. My answers may offend I believe in telling the truth, I use common sense as well as the law. Other state's laws may differ.. There are a lot of really good attorneys on this site, I will do limited appearances which are preparation of court documents it is , less expensive. However generally I believe an attorney is better than none.
An officer doing a thorough investigation certainly would photograph any injuries. Sometimes, however, they don't...for lots of reasons (bad cop, lazy cop, no camera, etc.). A photograph showing the injuries will surely hurt your case. Not having a photograph might help your case. Only an experienced criminal defense lawyer will know how to use this strategically to your advantage. And I strongly recommend you get one quickly...a robbery charge is a very serious allegation.
