CCD vs. CMOS

The first part of the clip shows the biggest attribute of CMOS: It's low-light capabilities. But when flash and quick pans are introduced, it falls by the wayside.

Tips and Tricks
 
That shooting environment is really designed to accentuate the jello vision.

I'm wondering how often we are going to shoot something similar.

However, it does show it well (or poorly).

of course it was. it was a test to compare global shutter to the CMOS global shutter artifacts.

when shooting a resolution test, you don't shoot a regular image, do you? no. you shoot a resolution chart... so you can accurately compare the effects in the test.
 
Of course that's true.

But most of us don't shoot that way.

Accurately portraying non standard shooting environments don't make much sense to me.

I actually do think whip pans are pretty common thing to do in narrative film making. Not extremely common, perhaps, but I've certainly used them. It's one of the reasons I didn't want a CMOS camera.
 
I understand what is being said, but whip pans in front of a steel picket fence are to be avoided.

And I agree that if this is something you do regularly, then rolling shutter ain't for you
 
The sony does seem to be a bit better in low-light from these clips.. but it's a LOT more noisey especially in the blacks and shadows.


I also think that this skew and the rolling shutter artifacts just suck. I shot a lot of concert footage where there's flashes and strobes.. and I shoot a lot from moving vehicles and in places where's there's lots of vibrations.. So far I've said no to CMOS.. but the new panny 300 has some merits for getting more sharpness out of a cam and more of an interview/client cam..


thanks for showing this.
 
I don't know how non standard that environment was, it seems to me that many of us may find ourselves in just those situations. Flashes take place at every wedding, sometimes many at once, especially at the important parts. I shot a wedding on Friday. As the grand entrance was being made flashes were going off from all directions. I could see that being a serious problem if those "artifacts" were to show up in the footage.
 
I was referring to the very fast pans, not the flashes.

Again, use the best tool and rolling shutter won't hammer in a nail.

:)
 
I agree with David... I don't do many fast pans, but what I do do is snap zooms for coverage. How does the rolling shutter affect those. One client of mine requested that as a "look" so wonder if the rolling shutter would be problematic. Either way, I prefer to shoot without the servo engaged.. just faster and more responsive.

Ahh, I see. Yes, most do not do whip pans, and if they do they are not generally left in the edit.

The flashes would concern me though, if my main camera were CMOS based. I do use an HV30 for B-roll but and have never experienced rolling shutter, but since the HV30 is not a low light camera, photog flashes are less likely to be a factor.
