a=imread('C:\Users\Nathan Donatell\Pictures\SanDiego.jpg');
g = rgb2gray(a);
b = im2double(g);
c= mat2gray(a);
D1=c .^(1/4);
D2=c .^(1/2);
D3=c .^(2/2);
D4=c .^(3/2);

subplot(2,2,1); imshow(D1); title('1/4');
subplot(2,2,2); imshow(D2); title('1/2');
subplot(2,2,3); imshow(D3); title('2/2');
subplot(2,2,4); imshow(D4); title('3/2');
