There is no such thing as photospectrometry. It's sometimes used when actually meaning spectrophotometry. This usage is incorrect.
Many methods are known: - iodometric titration - gas chromatography - infrared spectrophotometry - UV/vis absorption spectrophotometry - ion selective electrode - MOS sensors etc., etc. See the link below for a list of analysis methods.

Differential spectrophotometry is a spectrophotometric analytical technique in which a solution of the sample's major component is placed in the reference cell and the recorded spectrum represents the difference between the sample cell and the reference cell...basically it uses major component of system as reference and NOT solvent ..for example if a enzyme ligand system is to be assayed ..enzyme + solvent is reference and enzyme + ligand + solvent is test sample..its for quantitative detection.
spectrophotometry is a branch of spectroscopy dealing with measurement of radiant energy transmitted or reflected by a body as function of wave lenght %
By chemical analysis: Uv-vis absorption spectrophotometry, atomic absorption spectrophotometry, inductively coupled plasma mass spectrometry, inductively coupled plasma emmission spectrometry, polarograhy, phosphorescence fluorometry, flame spectrophotometry, etc.
The term "Spectrophotometry" refers to an instrument that is often used to determine the intensity of the various wavelengths in a spectrum of light. This tool is a part of analytical chemistry.
Spectrophotometry can be applied to the study of a large number of substances.
For example UV-VIS absorption spectrophotometry.
Atomic absorption spectrophotometry is a method in analytical chemistry.
by the use of optical spectrophotometry.
The Lambert-Beer law is the base of absorption spectrophotometry.
