If it is a grayscale image then use imagesc() or use imshow() with a second argument of [] as in

YourImage = imread('YourFile.tif');
imshow(YourImage, [])

If it is a color image then try

    YourImage = imread('YourFile.tif');
    ScaledImage = mat2gray(YourImage);
    imshow(ScaledImage);

mat2gray is misleadingly named and does not convert to gray.
