OK, thanks.

Hi all. I don't see a scanner forum.  Is this the right place to ask about them? My Epson Perfection 1200 has gone bad.  I notice that the new Epsons use LED lighting, and I wonder about the color...

Hi all. I need to double the magnification of an EF-S-mount Canon lens, but I don't need electronic control of it.  Actually, I should say I don't need electronic control of it if I can set the...

" they will discover that 4k video demands perfect lighting, oceans of memory, 250mpbs"

Perfect lighting? NO. Why would the resolution change the necessary lighting?

Your bitrate comment is on...

Canon led the way years ago and then gave up. They still don't have real downscaling of their images for video; after years of development time and complaints, they're still using line-skipping...

No, shitty, pathetic-bitrate, compressed-to-hell crap being peddled as "4K" is the future, just as sham "HD" is the norm today.

Take a look at the "HD" on YouTube. You're going to get the exact...

"SVGA"? "XGA"? What year is this?

State resolutions IN NUMBERS. Not the alphabet soup that died out in the early '90s.

"They do a lot of time lapse imagery."

Doing time lapse with this POS would be incredibly dumb, when you could get a point-&-shoot for less money that would kick its ass by a huge margin in every...

"There are NO TAXES in the USA for these things"

Is that supposed to be a joke?

Shove your spam. Again.

Moronic. They add this useless "4K" instead of a decent bitrate.

These cameras record garbage-quality images. They use excessively high-resolution chips and pathetic bitrates. Same boring...

"1920x1080 is "2k" in digital cinematography"

No it isn't.

"1920x1080 is "2k" in digital cinematography"

No it isn't.

"So they're not calling 1920x1080 "2k""

He didn't say they were. He said it's AS IF they were.

What does color and contrast have to do with resolution? Nothing. You're drawing pointless parallels with the "Retina" display.

24 FPS is too low, but 48 is fine. Beyond that, and you're bloating the hell out of the data payload for diminishing returns.

We can't even get HD at 24 FPS with a decent bitrate. 4K? HA HA HA.

Once again let's go with some wack dimensions that don't match anything currently used in Hollywood. Why require 4096 pixels across? Eh, 3840 is good enough. Nobody will notice a 6% degradation,...

This has nothing to do with noise, lag, or rolling shutter. What do you think movies are typically shot on now? Yep: 4K cameras.

Go ahead and shove your spam.
