wow, an architectural thread 8)
the company designs lighting, do they do fixtures or do they design lighting arrangements on-site?
any more details on what's being shot? colors, textures, sunlighting, reflective surfaces, hard/soft lights?
this same issue came up in my environmental systems class last year. my professor would occasionally show the class a series of photos, stopping at each one and saying "good lighting, bad lighting?" and the class would reply "oh, that hotspot there, and oh, that's way too bright, it hurts my eyes!"
but many of the spaces in the photos were on campus. i visited some of them and eh... the photos were not accurate. experiencing the lighting firsthand was very different from looking at photographs. i've come to distrust photography as an effective way to show a bit of architecture
this particular job is quite a tricky task! good luck with it
