Ok, I did search, here, in game, on the web, guess what, found nothing. But it's there, yep, with no explanation in any way, even in the CE booklet.
When on photo mode, in HD or replay, both, there's that option, L1 you know? that says AE Lock, I think.
Tried on and off, many times, see no difference.
Please, who knows what this feature is about?
Sorry if it's obvious, really, I can't figure out.
Solved! Go to Solution.
AE = Auto Exposure. Basically when you take a picture, the camera has a metering system that decides how much light comes onto the sensor and therefore what the exposure is (based on the aperture and shutter speed).
Having said that, in GT5, pictures are taken on some sort of auto function, and the aperture and shutter speed don't necessarily determine the expore, they are used only for determining the depth of field (F) and the motion blur (shutter speed). The exposure is beinng determined automatically based on thhe scene you are looking at.
So what AE lock does is keeps a set exposure even when recomposing the image.
As an example there are cases where there is a lot of bright sky in the image, the camera will expose for the bright sky, leaving the car as a dark silouette. What do you do in that situation, recompose the image having the car take as much of the viewfinder as it can, expose for that, lock it, then recompose it to the original. You will find that the car is properly exposed now with the sky being blown out most probably.
I hope I made myself clear, if not look at dslr tutorials on AE lock.
