Germans have started wearing facemasks outside the home as new rules come into force to curb the spread of coronavirus.
The use of cloth masks is now mandatory on public transport and, in most regions, within shops.
The rules vary among the 16 German states - Bavaria being the strictest, while in Berlin shoppers do not have to wear masks.
But the authorities are moving very cautiously in easing the lockdown.
Students preparing for their school-leaving exams are also back in class, but social distancing is in force.
German media report that mask-wearing is required in school corridors and when children go on breaks, but not in the classroom. Students sit in class spaced apart and there is more frequent cleaning with disinfectant.
Most German schoolchildren are still at home however, under lockdown, and kindergartens remain shut.
Monday also saw some further easing of the lockdowns in the Czech Republic and Switzerland, while Italy has set out a detailed plan for easing its lockdown, which remains one of the strictest in Europe.
The German authorities require mask-wearing at stations and on buses and trains, but not yet on long-distance trains.
Home-made cloth masks are acceptable; people are not expected to wear hospital-style intensive care masks. Masks are now on sale in station vending machines and at markets.
Masks now normal on German streets
Face-masks have become the new toilet paper, quipped one German newspaper commentator, as people across Germany scramble to buy nose-and-mouth coverings.
To plug the gap, signs are popping up in shop windows advertising self-made, brightly coloured cloth masks, typically costing around 10 euros.
In the hipper parts of town, patterned face-masks are a style accessory. Faces may be covered but Berliners are still keen to show their individuality.
"If I talk to the shop assistant — and if I have the virus without knowing — then it means that I don't pass it on to her," said Florian, a graphic designer, who was wearing a simple cloth mask while coming out of a shop. "It's about being aware and protecting other people."
But Christine, a special needs teacher, who wasn't wearing a mask and uses a scarf around her mouth and nose in shops, worried that mask-wearing is more about virtue-signaling than safety.
"The situation is really confused," she said. "Some people wear masks, some people don't. It makes the whole thing absurd. I think it's a bit of a placebo."
Either way the new rules are having a visible impact. Until recently face-masks were a rarity in Germany, and would attract stares. Now they are suddenly a normal part of daily life.
Germany has reported 5,750 deaths from Covid-19 - a much lower toll than in Italy, Spain, France or the UK.
Germany's large-scale testing and strict, early lockdown are reckoned to have kept the rate of infection down.
Last week the eastern state of Saxony became the first to make mask-wearing compulsory.
Mask-wearing is also compulsory in Austria, the Czech Republic and Slovakia, for shoppers and public transport users.
But internationally expert opinion is divided on the effectiveness of home-made masks in curbing Covid-19. Many argue that masks help prevent the wearer spreading infection, but frequent hand-washing and social distancing are deemed essential too.
In most German states children under six years old do not have to wear masks. And Schleswig-Holstein will not require mask-wearing until Wednesday.
The new rules have created huge demand for masks, so faced with a growing shortage the government is planning to manufacture millions of them in Germany.
In Bavaria, people still going mask-free can be fined €150 (£131; $163), but the fine for any shopkeeper who breaks the rules can be €5,000, Süddeutsche Zeitung reports.
Chancellor Angela Merkel has accepted that regional variations in the lockdown rules are acceptable because some places are virus hotspots, and others not.
