The end of 35mm adapers and hv20s....

NEW INFO ON EXPOSURE IN D-MOVIE MODE:

A) Activate EASY EXPOSURE ADJUSTMENT in the Menu

B) Switch back to LV mode after you've selected your Desired F-STOP (Considering you're using an automatic lens, manual won't matter).

C) Hold down the +/- Exposure button and roll the shutter adjustment dial (on the back) toward the left or right. You can adjust exposure in 1/2 or 1/3 increments depending on how you have it setup in the menus. On up to +1.5 for increasing exposure adjustment and down to -5.0 for decreasing.

I found that out right before I passed out in the camera last night.

More to come, and a lit sample as soon as I take back the rental car.

So I am guessing that means it only affects the shutter?

Thanks for your labor Kholi.
 
i just found a best buy with 3 in stock. first time i called they searched for "Nikon D90" and couldn't find it. I found the SKU (8975184), called back and there it was... 3 in stock. be back in an hour.
 
But, there's no way (yet that I have seen) to actually control the shutter freely.

I hope Joe might be able to shed some light on that idea. Or Drew or Andro.

On my 40D I was able to control the Shutter, ISO and Aperture while video-outing liveview. I posted a video earlier in this thread.

About hdmi out I'm guessing it won't be uncompressed. What kind of signal goes through hdmi cables usually?

It looks like that's how you change the shutter. At least in APERTURE PRIORITY mode. However, here's what I don't get: you can't change it with the AE-L Lock activated... and the camera, up until you lock the AE, will do what the hell it wants.

So, essentially, the camera is working against you in some regards. That's why I still don't believe you can set any kinda shutter by normal means. But, perhaps by using the +/- Easy Exposure Adjustment.
 
Thought:

Why would Nikon put allow movie recordings on a dslr camera and not allow you to manually adjust exposure just like when using it for stills? Do they think photographers all of a sudden turn dumb when it comes to motion?

That's because Canon's LV implementation has a mode (perhaps the default) that essentially simulates the final exposure. They also have a mode that just goes for max visibility on the monitor, which seems to be the only mode Nikon employs.

I can't fathom it, Hunter. And, to be honest I hope I'm just not seeing something really simple (often do that) about it that allows you to the freedom to change stuff up.

I even just slapped on a Vivitar 90mm Macro lens that's fully manual so I could emulate what Joe was doing with a full manual lens and you just can't change the shutter by normal means.

Now, after walking outside I can say that what I found out last night, the EASY EXPOSURE ADJUSTMENT--

Controls the shutter! The highest value you is a +1.5 and the lowest a -5.0. I can see the shutter actually changing in the LV screen and, when I have an auto lens on in Apeture Priority mode, the shutter changes independently of the F-Stop value as it should. You can see the effects right in the screen, from smeary at +1.5 with PLENTY of light to jittery/juttery high speed shutter at - 5.0 with little light.

We're getting somewhere.

The real question for me is, now: what the hell is auto actually doing? Adding gain or what? Because, until I lock it, the actual image keeps getting darker and lighter, depending on if I point it toward shadows or a bright source. Although it now doesn't effect the shutter unless Easy Exposure or the Exposure adjustment value is dead set on 0.0

Not enough development time ?

Deliberate crippling of features to establish a model hierarchy ?

yeah, the only thing keeping me from buying it is if I can't shoot under street light at night like in that jarvis clip. i imagine you can. but there seems to be a bit of a mystery as to how to bring the IsO to 3200.

Tested street light shooting last night, and the image was well exposed, but I was walking and hand-holding, so the clip looked terrible. Maybe tonight I'll do some Steadicam + street light footage if that interests anyone.

I wonder if it is consistent, like -5.0 is 1/4000th and +1.5 is 1/25th. I wonder how you would be able to figure it out. During playback, is there any meta data showing up about f-stop/shutter?

It interests me a great deal! Please do this if it's not too much trouble. :)

How noisey was it, Drew? You want to do a REALLy quick test for me?

Turn of AE-L, point the camera at a light bulb and let the auto do its thing. Lock it.

Turn it back toward a slightly underexposed area and record some stuff. Then, right after, while keeping the camera pointed at a slightly underexposed area, turn the AE-L off, let the Camera adjust, then lock it.

Record again.

Compare the two clips: is the first one cleaner as far as noise goes?

So...what is the application for this. You can dial in your own aperture, and it sticks, good. You can dial in your own shutter speed with easy exposure adjustment, good. But what about ISO/gain? Is that still fully automatic? Or can you turn off auto gain? If it was automatic, then I guess you could also use exposure compensation to bias the gain in the direction you want (creative situations won't always warrant the auto exposure result). Or you could turn off auto gain (somehow) and set it manually, but how?
