  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

MX Chip Sweetspot

The default setting is ISO800 for a reason.

Graeme
 
It is, but of much less significance.

beware that at 800/redGamma you have 1,4 ish stops highlightprotection, but that you'll either need to do something with the exposure in post or at least go redlogFilm, to be able to reclaim the top... if you need it.
 
The night and day difference between the old and the new chip is static noise.
On the old chip, you would start to see static noise when pushed above ISO 640 especially under tungsten lighting.
With the MX, I don't see any static noise even at ISO 3200.

The range ISO 640-1280 looks very very clean. At the higher end of this range grain starts to creep in at the shadows. Nothing alarming, but the image will get some life in the darkest graduations. I really like the look of this as the image sometimes get a bit sterile at the lower ISO's.

The camera is still cleanest at ISO 320 under daylight, but to me the look at ISO 800 is way better.

Be aware that you can experience some occasional horisontal "blooming" at the higher ISO's. They can occur if you have some areas that are overexposed by 1+ stops.
 
Blooming on MX ?

Blooming on MX ?

Notice the horisontal blooming at 0:38 to the right of the highlights.

Yes,

Strange effect. I wonder if the attached jpeg also shows this kind of blooming?

Shot on RED ONE MX (build of 20.07.2010) RPP 18mm.

Only seen on high iso settings (here 5000 iso).

PS: compression due to low jpeg kb...

Who is that guy in the clip, Anders? Handsome fella! ;-)
 
Blooming is usually lens related. When you really gain up an image you'll see things that are normally hidden.

Hi Graeme.
It only occurs for me when the highlights are blown out on the sensor. In this case if I added a nd 6 and compensated that with +2 gain stops in redcine X they were gone.....more noise yes, but the blooming was gone.
 
The fluorescent tubes also make strange horizontals lines that make me think it's not the RPP/optic fault but more a sensor thing...(?)

I know how CCD works but don't know if CMOs could have such a "contamination on pixels line" effect ?

Also it's only in the horizontal direction, if I rotate the lens 90° it is still the same.
