What Fred says.





Small tip: look at shadows in photographs. You can see where the lights were positioned, how hard of soft they were (aka if they use modifiers like soft boxes or not) and you can tell how high they were positioned.


If you get access to high-res pictures you can even tell what the lighting setup for the main subjects was from looking at the catch lights in the eyes (provided they were not retouched, something some photographers do in postprocessing).
