<span>I doubt if anyone knows the exact exposure time for any particular daguerreotype image. That being said, the typical exposure time was a variable between 15 to 40 seconds. This is because the plate was sanitized by iodine fumes. The time of the fuming was a variable. Depending of the quality of the camera lens and the brightness of the day let make a guess – the exposure was likely at about 30 seconds. 

The first permanent photograph was taken in 1827. The process was the invention of Nicephore Niepce and is titled A View From The Window at Le Gras. This picture was taken in France and it is now at the University of Texas at Austin. The exposure was 8 hours long. Leuis Jacques Mande Daguerre using an improved process took two pictures of the street titled Two Views of the Boulevard du Temple, Paris. Now at the Bayerisches National Museum, Munich.</span>

spin [16.1K]

Answer:

Explanation:

1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).

2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.

3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.

4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
