You didn't supply very much information on the photo. How large, what type of paper, digital or chemical printed, and are you simply wanting some information on just this one piece or are you seriously trying to start a framing business??
The reason I asked the last question is twofold. If you want to frame this one photo for a show and are not interested in all the whys and wherefores of custom framing things like old guns, kid's crayon drawings, shadowboxes with false teeth and old photos, then I would advise you to take the piece to a custom framer and have the job done correctly.
If you want to learn the framing business, I probably would recommend the same solution for this piece. There is much much more to learning to frame than a few questions and answers on the Grumble. And, since you didn't indicate any framing background in your "freelance artist" profile, I would suggest that you take some classes, read all that you can get your hands on about framing, ask questions here and on any other forums that you find, and prepare yourself to enter a business of much precision, frustration, elation, and satisfaction! There are professional framers who have been in business for many years who still don't know the basics of preservation framing. It isn't that easy to learn overnight.
I don't mean to be snobbish or to run you off, I want you to take a realistic look at what you are asking of us. Just to completely explain the entire process for "archivally framing" your photograph with all the framing terms that are used would take a very large post and probably become so confusing that you wouldn't get all the information you needed to do the job to standards. If you have some framing background or have worked for a framer in the past, then it may be easier to relate to the process. But, I have seen and spoken to a few "laypeople" who wanted to frame their belongings and the bottom line usually was they didn't want to spend the money to have it framed correctly.
I hope you take this post in the air of sincerity that I meant it to be. There is a mountain of help on the Grumble to help you with various steps in the mounting and matting process. But you really should have some idea of what you are doing before you step up and attempt to frame something for a showing that may be eventually sold as an "archivally framed photograph". Unless, it is done to the standards that it was advertised as being done, it may come back later on to give you grief.
