1. Using the cell.tif image, Create a Matlab script that can add or subtract a scalar value from a selected pixel based on the coordinates.

2. Now, expand the above method to add or subtract a scalar value to all pixels of the image.

3. Expand the above technique to an RGB image so that you can add a scalar to a selected color channel.

   Caution : Keep in mind that your pixel values have an upper limit. i.e. for an 8-bit picture, 255 is the highest value.
