D800 Dynamic Range in video mode?

[Donald Ong]

Nice way to make a blanket statement, get called out and then back track to attempt to add specifics.

You want to people to understand what you're writing, type more than one crappy sentence void of any pertinent information.

Firstly, my original statement was only there to tell the other person there is simply no way for a DSLR to do 14 stops in video end. Period. What is there to call out?
Its been proven time and time again that the d800 doesn't do 14 stops, and i was just addressing that.
That was my point and my only point. There was nothing more to it.

My second post would not have been necessary if you hadn't been obsessed with pointing out to me that the BMCC costs less than 3k. It too was a blanket statement as it told us nothing. We all know it costs 3k. We all know it does more stops than an DSLR...but it isn't 14 stops either. But that's besides my point. I was merely pointing out that current DSLRs simply cannot do 14 stops. Perhaps my choice of analogy could be improved upon, but what is so difficult to comprehend?

I also wasn't comparing the d800 to the RED, just pointing out that if d800 did 14stops, it would be in red/alexa territory, which it isn't.

Thank you....this sentence right here lets me know you don't know what you're talking about.

Even if the D800 did 18 stops...it still doesnt put it in the same territory as an Alexa, Epic, or F65...

*ONLY in terms of DR. I'm ONLY talking about dynamic range. Of course the D800 isn't in alexa territory even if it did 14.
I'm only talking about DR, which is the point of this thread in the first place.

Gosh.

Does anyone know the base ISO to get the best DR? 800?

According to the European Broadcasting Unions test of the D800 it has about 11.9 stops of usable dynamic range. The full report can be found here http://tech.ebu.ch/docs/tech/tech3335_s02.pdf . Interestingly they found that the D800 could not be recommended for serious program making, mostly because of unacceptably high levels of aliasing and moire.

This is what you get between the technical analysis and the esthetic one. With this level of test no Dslr except the GH2 would have been used the last 4 years. But you know what history tells us about the use of dslr in broadcast and even big screen movie. It goes much beyond just technical analysis. The 11.9 stop is already very impressive for any camera. It is in the C300 range. It would have been nice to see such test with a mosaic filter and a Ninja, to see if the outcome would have been different in terms of pure technical analysis. Another thing that I would have liked is the resolution they stated, how it would translate in lines.

If it follows the jpeg engine the base would be 100 and stay about the same until about 800 iso and even 1600 is very close.

So, pardon what might sound like a dumb question, but what might be a typical 'starter' ISO setting for a more-or-less conventionally lit interior studio shoot? In some of my testing I ended up at around 640. Does that make sense? I have to confess - I'm a bit unaccustomed to being able to shoot indoors with such a wide range of usable camera sensitivity settings. Quite a luxury...

You might consider putting the D800 in manual exposure mode with Auto-ISO selected. You can then set aperture and shutter speed as you wish, and rely on the camera's light sensing system to select the correct ISO. That will give you the widest practical dynamic range that your shooting conditions will allow. When shooting video with Auto-ISO, you'll probably want to press the AE-lock button before shooting, to insure the ISO remains constant during each take.

I have a D800 and also work with 5D mkII and MKIII's. Overall, the D800 handles highlights better which lets me get away with slight overexposure if im dealing with a high-contrast scene.

Unfortunately, this does not work. Setting Auto-ISO to on or off does not have any influence on video.

In M mode ISO is always manual, in P, A and S modes ISO is alway automatic.

Ah, too bad, I assumed that ISO in the D7000's M mode worked the same as the D5100.

Ive had my D800 for about three months now and one thing Ive learned about ISO is to never shoot below 200 iso unless in very bright areas (or outside), actually, I stay around 400 iso, even in well lit setups. The problem I found with shooting at the lower ISO is that you often get banding/posterization in the dark areas of your video shots.
Alot of argument on this post about the D800 vs. the 5D. Well, since there was no clean HDMI output on the 5D at the time I bought my Nikon, it was an easy decision for me as to which one to buy.

I can't see the disadvantage of shooting in shutter-priority mode, to be honest. The way I think about video cameras is that this is what they're doing anyway: the shutter speed has such a profound impact on the 'look' of moving subjects that many cameras spend their entire working lives at 1/48th or 1/60th. You vary depth of field by controlling aperture, then correct exposure by adding ND, light, or gain appropriately.

Shutter-priority and auto ISO gets you most of the way there; dialling in exposure compensation returns manual override. The extra ingredient to make this work is setting exposure lock to toggle, so you can prevent the camera racking exposure during a shot.

(NB: I've only shot with a D7000, the D800 may behave differently.)
