Before we get to choose 3D format instead of choosing what movie to watch before stepping in to the theater, there was a time when the ripple of silver screen still looking peaceful, 3D invasion has brought us plenty of wars.
When we keep talking about 2D, 2D term is widely used to differentiate and make clear the stand between 3D and 2D. That means actually Digital 2D brings out another definition:
Digital 2D gives you the clearest possible image quality on-screen, with absolutely no visible "tearing" or "artifacts".
For me, I redefined it as H-D.
Actually, Normal is the word you want to find for the original format of movie.
Frankly speaking, I strongly believe 3D will not replace 2D. If it does, you will see "Only in 3D" instead of "Only in theater" or "Also available in 2D" instead of "Also available in 3D". That will be a tragic. A big one. You know we always have a choice.
Let's go deeper into the dimension. If your eyes are smart enough, then you won't be expecting 3D anymore because your eyes won't fool by 3D. For your information, it happens to people but I won't say that it's a bad thing. What happens to me is, been in a long 3D movie ride, the 3D effect seems not be so obvious anymore. I got immunised to 3D. So sometimes I might just want to focus hard on it, perhaps to the particular object that I wish it is in 3D. Too much of the superpower, huh?
3D effect enhances one's vision experience, together with my new theory HD BEFORE 3D, you will feel that 3D is not entirely bad (harm our eyes and expensive pricing)
Of course I have some evidences to prove it right. This theory comes when I am watching 3D movies with my specs and 3D glasses on at the same time.
First, there was 3 sets of movie format can be found:
1) Normal type only
2) Normal type + Digital 2D
3) Normal type + Digital 3D
1) Normal type only
2) Normal type + Digital 2D
3) Normal type + Digital 3D
We can see that if there's no co-existence of 2D and 3D.
The film has to be modified to a clearer version before it goes 3D. 3D can be performed well after it is in a clearer version so you won't see a 3D-based movie with Digital 2D around. This proved that Digital 2D is included in 3D.
Somehow, most standards of 3D-based movies had gone down low due to the over-accentuation to the adaption of visual effect but not the plot. It's like "You won't get the same experience in 3D and 2D", emphasizing the best of 3D.
PS: My advice is choose to watch in this order: 2D> Normal. Still, 3D is still optional.
Honestly, I prefer 3D for blockbusters. Let's just get the taste of it, don't get so obsess with 3D.
