How to get Image information (imtool) - Image description using command prompt function

I have developed algorithms which use certain inputs which are available in IMTOOL -> Tools->Image Information -> image description. How can I access this information through coding so that it will generalized and can avoid trouble at user end to provide those info. For instance in image description (attribute) for one of my image which is taken through LEICA microscope - i have the following details
Camera information: Calibration= 0.058 Microns per pixel; Capture format= 1024 x 768, XGA HQ; Gamma= 0.77; Gain= 2.5 x; Exposure= 1.0 s; Auto exposure= Off; Image type= Colour; Shading= Test 1; Sharpening= High; Black clip= 5; White clip= 229;
Microscope information: Nosepiece Objective Mag.= 100; Mag changer magnification= 1; Aperture= 1.25;
Some of these information are being used for processing.

You could *try* http://www.mathworks.com/help/techdoc/ref/exifread.html
Gamma does not appear to be on most JPEG tag sets,http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/JPEG.html
but it is a known EXIF tag, 0xa500

Cameras tend to use colorspace response profiles rather than using just one gamma for all spectral frequencies.
