I come from Maxwell's english site, and miss so many things here cause i don't speak spanish
Mane162, could you please post this tutorial on English site?
Thanks a lot
hello def4d, i have tried to explain it in english, so sorry for my mistakes, here i go!!!:
A TODOS LOS USUARIOS DEL FORO EN ESPAÑOL, VOY A POSTEAR UNA PARTE EN INGLES A PETICION DE UN MIEMBRO DEL FORO, CORRESPONDE A LA PRIMERA PARTE EL TUTORIAL Y NO AÑADE NADA NUEVO A LAS EXPLICACIONES INICIALES:
MOTION BLUR CONCEPT
Why does it happen ?
A camera works by exposing a sheet of light sensitive film to a scene, for a short period of time. The light from the scene, hitting the film, causes the film to change chemically, and eventually results in a picture representation of the scene. This is known as an exposure. If the scene changes during that exposure, a blurred image will result.
Why should you bother ?
You will see motion blur to some extent in almost every film and TV program. It is likely, however, that you will not notice it. Like many artifacts of photography, you only usually notice it's absence, and it's presence gives an air of realism.
For example, you may have seen that lens flare has become a popular effect recently. Traditional photographers often try to reduce it's effect, but since we recognize it as an artifact of reality, computer graphicians make the effort to simulate it. The same goes for the grain on film, the wobble of a camera being held in the hand or mounted on a helicopter, focus effects, and many others.
In more detail ?
We will consider how a movie camera takes pictures of a moving scene.
A movie camera consists of the following parts:
Lens
The lens focuses the light onto the film
Shutter
The shutter opens for a fraction of a second to allow light onto the film
Film
The film contains light sensitive chemicals. These chemicals record the pattern of light falling on the film. This can then be used to create an image of the scene.
Take a look at some computer animations that do not contain rendered motion blur, and you will see that fast movement looks jerky and unrealistic. You might also notice this effect in TV coverage of sporting events. Whereas most TV programs are filmed with cameras that take about 25 frames per second, sporting cameras can take up to 1000 frames per second, giving excellent sharp slow motion replays. However they broadcast only a small fraction of these frames, which reduces the amount of motion blur, and so fast moving objects seem to flicker.
We are all so used to seeing motion blur in TV programs and films, that to see motion without it looks a little unrealistic. The lack of motion blur is one of the (many) reasons that computer generated animation can look unreal. This lack of realism is caused by the sharpness of motion in computer animations is quite noticeable, and can really spoil the effect.
TO GET MB IN MAXWELL:
1-build your anim
2-select your objects, right click on them, choose properties, set motion blur radio button to "object"
3-do the same for the maxwell camera
4-don't forget to adjust shutterspeed properly (works as in real life)
5-hit render
i hope i can help you
