Just how big is 4k?

I have a 23 inch apple monitor and for the first time it felt small. :(

Imagine how people who own the 30" must feel. Who thought that thing would feel small any time in the next decade?

those that don't have the size. :)

This camera is sounding amazing and I have to say having a person as successful as Jim Jannard responding on this board is very, very inspirational.

EDIT: this isn't a dig against all the other great people on this board. :)
 
I can't fathom 4K running at 24fps. It's like trying to understand the width of the galaxy in terms of travel.

RED sounds incredible. I can't wait to hear more.
 
And here I was thinking about upgrading sometime in the near future from my 23" to the 30" apple... what's the point. You can't win with images that large on the loose. I'm going back to my 15".

:crybaby:
 
man, that sucker is huge. didn't realize how big 4k was...damn red ticker...the more i watch it, the slower it seems to get!?

Isn't RED bigger than 4K? 4520X2540 is more than 4K I believe.

According to Ted Red in his DV.com interview the "Mysterium" sensor is a CMOS using a Bayer Pattern array. This generally give a real resolution of about 25% less than the actual number of pixels in the array. A Bayer Array of 4520x2540 will therefore work out at about 4k.

I think.

The resolution out of a bayer sensor depends a lot of on the demosaic algorthm used and course the source image. I used to take the general rule of bayer is 75% of the sensor, but since working with more advanced debayer filters, we finding in most real-world situations the resolvable image can approach the kell factor. One reason the luma resolution can still be high despite the bayer sampling, is the RGB filter are not (never are) pure. As a result ever pixel location has luma more information mixed with chroma, resulting in a suprizing sharp image.

It's never that simple, is it :)

But taking the "75%" rule as a general principal, the resultant image resolution should be around 4k - possibly higher than 4k if what you say works out.
