Don't know Silver Salmon Lodge but spent a week at Royal Wolf Lodge a number of years ago. It is about an hour north of King Salmon by float plane.
Was it tips on photography or tips on flyfishing you wanted?
If I was going back to fish Alaska, I would concentrate my photography on bears. You will get some wonderful opportunities to photograph them while fishing (but, if one ambles along the river bank while you are fighting a fish, break it off. The last thing you want bears to learn is that anglers mean salmon.
