Both of those cameras are very good. But for a bridge I would look at the canon sx50 far better in low light.
go to the place where the wedding will take place and imagine the ceremony then do a dummy shoot take photographs as if the wedding was happening both in doors and out also try different weather conditions
Find a local wedding photographer and ask if you could offer your services free of charge just to see how it's done.
That's canon raw but the program isn't the best as I said go to adobe and down load camera raw it's a none destructive program that will save the shot you want and the original file
You haven't said if your using raw or JPEG if it's in raw try using camera raw free download from adobe web site.
In the digital age if you don't have at least 3 copies of your files you don't have any at all. I keep a hard drive in my bank only take it out once a month to back up.
