Visiting churches is one of the absolute highlights of a trip to Europe, and provides a fascinating insight into the most powerful influencethat has shaped European cultures of the past couple of millenia.
Unlike some other religions - where access to places of worship may be restricted to members of that religious group or a specific gender - the vast majority of Christian churches will allow tourists to visit at most times, including routine services (although some may charge an admission fee for doing so, and access may be denied for private events such as weddings and funerals). However, tourists should realise that most churches are still active places of worship, and so visitors need to exhibit a certain sensitivity to display respect to the culture and avoid giving offence to people at prayer.
The following guidelines are based on wonderful advice offered by Homer (homaned) - who does this for a living - in a forum response, and although specifically written for Christian places of worship, would apply equally to places of worship for other religions
So, here is a general list of do's and don'ts for people wishing to photograph during a church service:
READ THE SIGNS
If photography is not permitted - because, for example, it may damage paint on delicate murals - this will usually be indicated by a pictogram of a camera with a red line through it. Under most circumstances, you can assume that photography will be allowed (unless otherwise indicated), but may not be permitted during services. If in doubt, ask for clarification - this shows respect and will very seldom be met with anything other than a helpful response.
TURN OFF YOUR FLASH!
Every camera on the market has a button on it which will turn off the flash. The number one most alarming and distracting thing that can happen during a liturgy, and one which will even get you kicked out of some churches, is the bright flash that goes off when you take a picture. Not only is it distracting, but it usually makes the picture turn out dark, because your camera's flash only has about a 10-15' range. Turn off the flash, and hold the camera up against your eye, using the viewfinder, and you will likely get a better picture (and you definitely won't have any red-eye problems!).
DON'T MOVE AROUND ALL OVER THE PLACE! (UNLESS YOU HAVE PERMISSION)
Instead of walking all over down the main aisle and in front of everybody, pick a good place from which to take a picture at the beginning of the liturgy, and stay there. Unless you're a professional photographer with practice at stealthily moving during liturgies, you're a distraction, and you're being disrespectful. Even if you're a pro, try to stick to one out-of-the-way place, and use a zoom lens and zoom in to get pictures. Walking in front of people is a surefire way to distract and disrespect and closing in on priests or other celebrants just to capitalise on a photo opportunity is offensive.
TURN OFF THE CAMERA'S SOUND!
Every camera has some way to mute all its 'cute' beeps and clicking noises. If you press a button, and hear a beep, or if you take a picture and hear an obnoxious shutter clicking sound, you need to turn off those sounds (the muting option is usually in one of the menus). Along with the flashing, it's an obvious sign that someone is taking pictures and not showing much respect for those trying to pay attention to the liturgy.
TURN OFF THE 'FOCUS ASSIST' LIGHT!
If your camera can't focus without the little laser-light that shines in everyone's eyes before your camera takes a picture, then don't use your camera. You have to turn that light off! It is very distracting to be watching a lector or priest, and see a little red dot or lines pop up on his face all of the sudden. It's as if some rifleman is making his mark! Turn the light off (again, look in the menus for the option to turn off the 'AF assist' or 'focus assist' light). If you can't turn it off, put a piece of duct tape or some other opaque material over the area where the light is, so the light won't shine on someone.
TURN OFF THE CAMERA'S LCD!
You should never use the LCD to compose your shots anyways; just put your eye up to the viewfinder, and that will not only not distract, it will also steady your camera against your face, making for a better picture (especially if you don't have the flash on). And if you must review the pictures you've taken, hold the camera in front of you, down low, so people behind you don't notice the big, bright LCD display on your camera
CERTAIN PARTS OF THE CEREMONY ARE PARTICULARLY SENSITIVE
The consecration (blessing) of the eucharist (bread and wine) and distribution of communion to the congregation are considered to be particularly sacred parts of the service, and it is offensive to photograph these activities.
The main thing is to try to be respectful of the culture and of other people present at the service. Don't distract. And, if you are asked to not take pictures, or if there's a sign saying 'no photography allowed,' then don't take pictures. You can always ask a priest's permission before the liturgy, but if he says 'No,' put away your camera and enjoy the freedom you have to focus on the privilege of being able to share an experience with people who consider these religious rituals core to their culture and identity, rather than focusing on your camera's LCD!
Homer's Rules ... Homer rules!
Accomodation can be a problem in Lindau. Of course this is very true for the island. Off the island there might be more chances, but on the island everybody is going crazy. First, the information bureau was closed in midday when we got there, because it was weekend (?!). Then, the information panel there showed vacancies and prices .. when calling the hotels, either there were no vacancies, or the price was way over the one posted. Beside the 180EUR and up rooms at the fancy hotels on the marina, the cheapest rooms are 80EUR and you will run like hell when you will see those. Poorly lit, in an attic somewhere, with greasy owners. Well, I'm exagerating a little, but you won't find decent accomodation under 120EUR - like a three star hotel right near the Info point and the railway station.
Try to avoid the small little tacky hotel near the bahnhof. I forget the name but it sucks in comparison to other hotels. Also dont go to the one loud disco bar on the northwest end of the island. Just a little too weird for my taste. Stick to the local beer.
