problem in imfinfo give me the following error

I have done the following code

clear all,close all,clc;
originalImage = imread('101_1.tif');
testImage = imread('101_1.tif');
originalInfo = imfinfo(originalImage)
fakelInfo = imfinfo(testImage);
 if(getfield(originalInfo,'ColorType')=='truecolor')
     originalImage=rgb2gray(imread('101_1.tif'));
 else if(getfield(originalInfo,'ColorType')=='grayscale')

           originalImage=imread('101_1.tif');

           else
                error('The Color Type of Left Image is not acceptable. Acceptable color types are truecolor or grayscale.');     
           end
   end

    if(getfield(fakelInfo,'ColorType')=='truecolor')

       testImage=rgb2gray(imread('101_1.tif'));
   else if(getfield(fakelInfo,'ColorType')=='grayscale')

           fakelInfo=imread('101_1.tif');

           else
                error('The Color Type of Left Image is not acceptable. Acceptable color types are truecolor or grayscale.');     
           end
   end

But when I run this code it shows me the following error:

Error using imfinfo (line 80)
Expected FILENAME to be one of these types:

char

Instead its type was uint8.
Error in teste (line 20)
originalInfo = imfinfo(originalImage)

how can I solve this.

orig_fname = '101_1.tif';
test_fname = '101_1.tif';
originalImage = imread(orig_fname);
testImage = imread(test_fname);
originalInfo = imfinfo(orig_fname);
