I don't understand how car models got brought into this, but Photomode isn't dependent on models alone. It's more about lighting and reflection. F5's cars seem far, far too shiny, and GT6's can seem far too dull and flat, which can then give F5 the "Realistic" look in comparison, just because the car is more reflective. But in a real life comparision, GT6's relfections can be much more spot on.
Another than can lean in F5's favor is "
Oh, those GT6 shots are edited. They don't look that good in game." But the thing is, if F5's photomode is still the same as 4, you're doing the same thing. It's just in-game. Forza 4 had contrast, saturation and brightness adjustments, where as GT5/6 is a
real camera, meaning that editing is meant afterwards. And lets face it.
Every photographer edits their pictures. If you say you don't, you're lying.
As for the Interior debate... Really? Does it even matter? Just cause a car doesn't have an interior means it sucks, and the game sucks too? What I find sad is that GT6's Yellowbird looks better, an upgraded PS2 model
essentially, It's not quite Premium level, but is atleast on par with Forza's. But then again, this is about lighting and rendering. Both games can produce their amazingly realistic shots, but I have to side with GT's more professional, and realistic photomode.
And yes. Those are untouched, straight from GT6.
