  • 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 :)

Hello guys I was invited to a Beach Party where I had my Monstro at my car. So I decided to give it a try to see how it performs with low light which I was quite impressed. I just had one glass with me at the moment and not a lot of idea of what I wanted to shoot but I hope you guys get a feeling of the camera.

I was shooting everything at 74 FPS.
800 ISO
And between 1.4 and 5.6 in the aperture.

Cool!! Seems kind of posterized - was that a look? Would love to see a couple R3D's from this session
 
I am sorry but if this is Monstro I am not convinced.
I hope there is something wrong in post workflow.

Did you use STO OLPF? Why do you shoot so low ISO? Thanks for your link.

Just not to start the stage ISO discussion, It has little or nothing to do with shooting as it only part of the developing process. Would be great to see it developed on 6400 ISO think it would look quite spectacular with pics black backgrounds and the fire light playing far out in the audience all in slow with still not much noise and most of the highlights covered.
 
I would also like to see a R3D. The colors are posterized and the blacks are crushed, the ISO800 doesn't work in this setting. If Monstro is as good as it's proposed, then you should be able to do a ISO6400 with highlight protection at ISO640 in the grade. I would love to see that image.
 
Sure, I’ll be happy to upload the R3D files, Ill be uploading 2 clips, bare with since they are 12GB. Again this wasn’t a planned shooting I was just fooling around, with low battery etc.

It doesn’t have a lot of color grading just a little of IPP2, and the sensitivity of the light was higher than on helium IMHO so I tried to make it darker in some shots.

Also I used Standard OLPF, and to be really honest, I'm shooting at 74FPS! thats really fast for a beach shot at 12:00 PM. I didn't expected to get so much light in.

I didn't push it to 6,400 because I wanted a darker image with solid blacks.

You could do a R3D trim? A second of footage is enough, wide shot with fire and audience in frame :)

Shooting fire like this is a challenge. The DR is crazy so to hold the texture in the flame (and not have it just a blown out blob) you have to underexpose the background. If expose as normal, ETTR with no Stop Lights, then you have to go dig out the shadow detail in post. I shot several Poi spinning sessions with my Dragon with little luck. Noisy af when I held the flame detail. You have to have some fill light to reduce the DR - like shoot at dusk. RED cameras like to be fed light. Starve them and strange things happen ;-)

Anyone else have experience with shooting fire in pitch black?

Here is a monstro FF frame with compression 15:1 shot in shitty tungsten light and developed at 800ISO.

Love the above frame but . . . thing is with fire spinning is that, to me, it's one of the most challenging and universally reproducible tests of DR. With a commercial set shot, I have no idea how it was lit or the contrast ratio between brightest and darkest areas. The standard 'man lighting a cigar' shot that everyone likes to post is also not that challenging. The light coming off a burning Poi ball is 10x brighter than a match light. Expose for Poi ball flame detail - then check the background for detail and noise. Same test in Paris as can be done in Peru.

Some shots done with smart phones - the flames are mostly overexposed by a couple stops so you can't see the flame detail. That's auto exposure for ya

I would have shot it 2000iso or more with the LLO on Dragon. To protect highlights and you still have nice details in the shadows.
I've shot a feature at 1600 and found it way to clean (5.3k once full debayered).
If monstro is cleaner than Dragon it's IMHO an error to use 800iso for big DR situations as you usually make the stop decision on behalf what you see in the evf. So yes it's metadata but once you clipped, it's not anymore... And a night scene can take some noise, it's more commonly acceptable.

Would love to see this Monstro 2000iso, LLO, Poi Spin test actually done. Again, this to me is a true reproducable test of DR since the flame with detail is a fixed exposure - the shadow background detail and noise level (at that exposure setting) is the only unknown between cameras
