I'm going on my understanding of blackshading from Deanan (when he was at RED) and when I first ran into HOT PIXELS with the original RED ONE.
At that time Blackshades were only required at the shutter angle, framerate and, TIMEBASE.
Other that what was recently posted in this thread as quoted by Deanan, that is all I have to understand it from the source.
Most of the "problem noise" is blue channel noise. From what TED has explained to me in interviews for articels I have written, it's wise (in the M days) to "activate" the blue channel, particularly with Tungsten sources (by using blue gel or a blue filter) to help eliminate some of the blue channel noise caused by low light or tungsten sources.
In further tests I have found that this works well with the MX sensor as well in both the EPIC and the RED ONE MX.
I've never heard from any RED source that the metadata affects BLACK SHADING CALIBRATION other than the shutter, framerate and timebase.
Hope this helps.
"How to expose" is really a subject for another thread. Hearing of noise issues from the common user it would be great to have some feedback from the factory how features like Spiderman4 and The Hobbit dealt with it as it doesn't seem to be a problem isolated to a specific Epic.
Some of you guys are making this out to be way more than it is. Or more difficult than it needs to be.
My kids shoot my EPICs with ease, none of them come to me with badly exposed images either and they don't even know what a histogram is or let alone understand it. I just say spin the aperture ring around until the picture looks right... So far they have 100% success rates.
I've been shooting RED for 4 years now... (yes I was a very early adopter - build 14 days.. camera 158 was out first)
Back when a highlights were a huge problem... I was getting perfect exposures then, and still get perfect exposures now.
It's not rocket science Will... why do you think it has to be.
Also, What I see in post is what I want I shot on set... why would it be any different? ... All my data, goes to REDLOGFILM, all my onset meta data gets deleted, as I don't need it. I create new LUTS that suite my purpose, I don't use any onset meta data at all, ever.
Maybe you should get to know your cameras a bit better. :))) The word "EASY" is an understatement.
No, the metadata doesn't affect the black shading.
People think they expose correctly a scene by changing metadata to 3200k, when in fact they are just pushing a channel and adding noise.
On the present case shown by Mr. Haase, I don't know if he had another issue? Is the Epic really noisier than the One-MX? I should test... But my "impression" : it's not...
Black shading can have an effect on the noise level IMundertanding if the BS calibration wasn't done properly for that current setting (Build/FPS/shutter).
If the calibration was done for 1/2 second exposures then that setting might not be great for high speed shots.
Thats sort of it basically.
I looked at ERICs R3D and I did not think it had excessive noise compared to a RED one MX. But if I zoom past 200% I start to see some.
Thanks for starting this great thread. There is a lot of rich information here. If you have looked at tons of MX before and then this is your conclusion then I just have to trust your judgement. It could be the larger frame size. What if you do a 4K comparision to a 4K shot you did on R1 MX and do 4K and 4K side by side.
If you say it's noiser, I trust that based on what you are saying here. Strange, personally I find the EPIC stuff sharper with less noise, and, then again, they are different cameras, even though they share the same sensor.
