Question about color space and resolution
on Oct 30, 2013 at 2:45:40 am

Hi, folks.
I am wondering about the benefits of a 4K camera. I know the resolution of 4K is 4000 pixels (as compared to 1920 pixels for HD), but does this additional resolution inherently affect the color space. In other words, is the additional resolution (i.e. more pixels) the reason I would get better color space?
Thanks very much for your expertise. I am (obviously) somewhat of a novice.
Vic

Resolution can definitely help when it comes to color and color space and how that relates to good image quality. A big factor that relates to "good colors" and "good image quality" come with the sensor the RED has and the compression it uses. RED has a ton of latitude and uses a 16bit wavelet based compression... to put it simple, it makes great images with a lot of latitude, using a great compression method, with a flexible RAW based format.

Thanks very much, Matt. Someone once explained it to me this way:
More resolution = More pixels.
And, a greater number of pixels means more color possibilities.
From that, he deduced that higher resolution results directly in more colors.
However, I forgot about the impact that compression has on an image.
So, again, thanks very much for that.
Just wondering...
If two cameras with the same codec shoot the same image, but one camera has more pixels, would the greater resolution, in and of itself, provide more color space?
(I hope this question makes sense)
Thanks again.
Vic
