<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>

Ainat [17]
<h2>Answer:</h2>

//import the Scanner class to allow for user input

import java.util.Scanner;

//Begin class definition

public class FirstAndLast{

   //Begin the main method

    public static void main(String []args){

       

       

       //****create an object of the Scanner class.

       //Call the object 'input' to receive user's input

       //from the console.

       Scanner input = new Scanner(System.in);

       

       //****create a prompt to tell the user what to do.

       System.out.println("Enter the string");

       

       //****receive the user's input

       //And store it in a String variable called 'str'

       String str =  input.next();

       

       //****get and print the first character.

       //substring(0, 1) - means get all the characters starting

       //from the lower bound (index 0) up to, but not including the upper

       //bound(index 1).

       //That technically means the first character.

       System.out.print(str.substring(0,1));

       

       //****get and print the last character

       //1. str.length() will return the number of character in the string 'str'.

       //This is also the length of the string

       //2. substring(str.length() - 1) - means get all the characters starting

       // from index that is one less than the length of the string to the last

       // index (since an upper bound is not specified).

       // This technically means the last character.

       System.out.print(str.substring(str.length()-1));

       

       

       

    }  // end of main method

   

} //end of class definition
