Is 70mm large format?
Unsourced material may be challenged and removed. 70 mm film (or 65 mm film) is a wide high-resolution film gauge for motion picture photography, with negative area nearly 3.5 times as large as the standard 35 mm motion picture film format. As used in cameras, the film is 65 mm (2.6 in) wide.
What size film does IMAX use?
IMAX technology uses the largest commercial film format in motion picture history — 70mm, 15-perforation — three times the size of regular 70mm, and ten times the size of conventional 35mm which you would see in a normal movie theatre.
Is 70 mm the same as IMAX?
The biggest difference using IMAX cameras with 70mm film is that they capture the shots in a 1.43:1 aspect ratio, which is roughly the same width, but taller than standard 35mm film. Above you can see a single 2.35:1 Cinema frame compared to a 1.43:1 IMAX frame.
Is 70mm medium format?
Medium format 70mm still imaging was done using film that, for the most part, ran vertically through medium format cameras. It was slightly (0.35 inches or 9mm) wider than 120, 220, and 620 film that all used the same 2.4 inch (60.96mm) width stock.
What ratio is IMAX?
When it comes to cinema spectacle, there isn’t anything that can compete with a full-frame IMAX 1.43:1 aspect ratio image.
Is 70mm film 4K?
It is estimated that 35mm film has a digital resolution equivalent to 4K: 35mm Imax film equates to 6K, while 70mm Imax is closer to 12K. Regardless of how they are shot, most films will be converted into a digital format for editing, colour grading and VFX (called digital intermediate and usually at 2K resolution).
Why is IMAX a different aspect ratio?
What makes Imax Enhanced different is, well, the Imax part. Movies that are shot for the gargantuan Imax screens have to use special cameras that shoot in a taller aspect ratio—the shape of the frame—than movies typically use.
Do they still make 70mm film for IMAX?
No problem glad the post was useful. While they probably have 70mm film out made, but given how rare the projectors are now a days unless an IMAX location only has a 15/70mm projector (like maybe a educational one) I would assume this would be a 1.90 digital presentation, 2K or 4K depending on venue.
What is the correct IMAX size for a movie?
IMAX’s standard digital specification is 1.90 : 1, and this film was formatted specifically for 1.90 : 1 for IMAX. If the screening is 2.4 : 1, that’s not IMAX because it’s not the IMAX digital spec. I saw a 2D standard screening in 2.4, and saw a small IMAX (liemax) screening in 1.9. Sorry if I wasn’t clear.
What is 70mm format film?
Films formatted with a width of 70 mm have existed since the early days of the motion picture industry. The first 70 mm format film was most likely footage of the Henley Regatta, which was projected in 1896 and 1897, but may have been filmed as early as 1894.
What is the difference between IMAX and 15/70?
The screen sizes in these auditoriums are much smaller than those in the purpose-built auditoriums of the original 15/70 IMAX format, and are limited to the 1.90:1 aspect ratio. Another disadvantage is the much lower resolution of digital IMAX.
