It isn't necessary to take any action for a photograph to be protected. Copyright protection is automatic, as soon as work of sufficient originality is "fixed in a tangible medium, perceptible to human eye, machine reader or other device".
If you do decide that you want or need the additional protection a formally registered copyright can afford, contact the copyright office in your country for the proper procedure.
You will need a graphics editing program (Photoshop, Paint Shop Pro, GIMP, etc) capable of applying text to your photographs. The following should be included as your copyright notice...
1. the © symbol (in some cases (c) is substituted), the word "Copyright" or abbreviation "Copr.";
2. the first year of publication; and
3. the owner of the copyright, either by name, abbreviation, or other designation.
In order to overlay text you will need a graphics program capable of photo editing (Adobe Photoshop, Paint Shop Pro, GIMP, etc)
