Red One MX – Noise and Slowmotion Test

This is a test of underexposing the Red and pushing it in post. And some footage from the 100fps Over Crank Slowmotion.

Today it was really cold (-20ºC/-4ºF). Therefor I stayed inside and played with the R1MX.
Firstly I finally read the manual and learned the different exposure and focus aids that are available in the EVF and viewfinder.
And there was a lot of them, more about that in another post.

While calibrating my Zebra settings I got a bit curious about underexposure and did a series of tests.
The conclusion I drew was that the Red Raw is very pushable.
Like all cameras it introduces noise when starved from light, but the noise isn’t to shabby looking.

Its nice to see that even the darkest one, f22, can be used in documentary purposes. Meaning you can shoot something and show what it looks like. We are not not talking about looking pretty, just identifying an object.

The frames

All of them are shot at ISO 800 with a Nikon 35-70mm f2.8.
The cameras is at its highest compression, in other words, its worst image in 4.5K.
In the camera the Zebras are set to indicate over exposure and shadows that are at risk to be to noisy.

The frames have first been exported in their default Red Gamma 3.
Then I have used the f2.8 as bench mark and pushed all the others to match its lift, gama and gain.

f2.8
Here I had Zebras indicating clipping on the table next above the remote.

On the stoplight we see that its the red channel that clipped.

Nothing to report.

Something weird happened here with the red channel. To lazy to redo :)

f8
Starting to get dark.

f8_resized

Past the point of under exposure imo.

ORGf8_1.4.1

Still sharp and not to noisy.

f8_1.4.1

Colors back to normal.

f11
Some Zebras warning for under exposure on the remote and parts of the blanket.

Tough to see on the picture, but there are some green zebras there.

ORGf11_1.5.1

Straight from camera.

f11_1.5.1

Some noise but still under control.

f16
Night time.
f16_resized

Camera doesn’t like those shadows.

ORGf16_1.6.1

This might get noisy.

f16_1.6.1

Should be able to clean it up.

f22
Green Zebras all over the place.

Warning!

ORGf22_1.7.1

Yeah right…

 

f22_1.7.1

Like I said, for documentation its ok. Words on the books are perfectly readable.

Slowmo

So for reading through that boring stuff, here is some slow of birds :)
