Super Members Mattias Burling Posted January 16, 2016 Super Members Share Posted January 16, 2016 This is a test of underexposing the Red One MX 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. While calibrating my Zebra settings to show the same as one of the false color modes 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 framesAll 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.(sorry about the photos of the monitor, smartphone.)f2.8Here I had Zebras indicating clipping on the table next above the remote.The stop light indicates that its a red channel clip. Meter is also on red.Straight from camera.Balanced.f4No Zebras for clipping nor underexposure.Straight from camera.Balancedf5.6No Zebras but exposed to the left.Straight from camera.Obviously I slipped in and made the red channel blow, but Im to lazy to redo it f8Starting to get dark.Still sharp and not to noisy.Colors back to normal.f11Some Zebras warning for under exposure on the remote and parts of the blanket.Straight from camera.Some noise but under control.f16Night time.This might get noisy.Should clean up in a pinch.f22Green Zebras all over the place.Yeah right....Still usable in documentary situation where the goal is to identify and not to look pretty. SlowmoSo for reading through that boring stuff, here is some slow of birds sam and kaylee 2 Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted January 16, 2016 Administrators Share Posted January 16, 2016 What ISO would you have to set on a DSLR to get the exposure you did at F22 with the push in post?It doesn't look at all bad! I bet it is like having usable ISO 25,600 in post.MX sensor definitely not a ISO 800 max like the Blackmagic Production Cam. Quote Link to comment Share on other sites More sharing options...

I bet it is like having usable ISO 25,600 in post.MX sensor definitely not a ISO 800 max like the Blackmagic Production Cam.I don't know really. Im a bit curious to do a side by side with the BMCC and push both to match the same exposure and compare. I can throw in a GM1 as well as an example of a smaller and low cost option.Yeah, definitely more usable for this type of stuff than the production camera.

Nikkor Posted January 17, 2016 Share Posted January 17, 2016 6 stops difference, if the base iso is 800 than f22 pushed should be iso 51200. In a real test you would match the exposure. Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted January 17, 2016 Administrators Share Posted January 17, 2016 How about a low light test versus the A7S in natural outdoor light or by street lights? It would be interesting to see exactly how far the MX ISO 800 pushed in post can go. Quote Link to comment Share on other sites More sharing options...
Super Members Mattias Burling Posted January 17, 2016 Author Super Members Share Posted January 17, 2016 I think maybe Ed could do that. Belive he had access to a A7s recently. Unfortunately I dont.Im gonna see today if the BMCC can have its exposure matched as easily as in the first test. Quote Link to comment Share on other sites More sharing options...

Administrators Andrew Reid Posted January 17, 2016 Administrators Share Posted January 17, 2016 You get a lot for your money with these deals.If the R1 was lighter, I'd go for it.For now going to persevere with my FS5 and 1D C! Quote Link to comment Share on other sites More sharing options...
