Yes, I ran out of room on the server in mid frame on one of the tower pictures.

The pictures are RAW. I sent them from tape to the SD card in the camera and copied them from the card directly to the website. I'm not kidding around. Not with a $2000+ piece of equipment. (to me that's a lot of dough... I ain't no starving Indi film maker, ;-) There are NO MODS on those pictures.

I had some severe ND on there, an ND4 + two CP filters (as a variable ND) adjusted so that the sky was OK. Shutter speed was at 60 and F-stop was probably somewere around 2 or 4. I think I could have used a bit more ND to be honest. That might have made the white of the tower a bit less than 255, maybe reducing the EE effect.

Gordon - What kind of matte box or filter holder do you have?

I wasn't using anything specifc. Would that make a difference? I assumed (we all know about that...) that since I was not heading into the sun, it would not be an issue.

I'm just a casual family shooter, so you're beyond me already. ;-)

Gordon,

I hear ya, man! I'm so dependent on my DP that sometimes I'm clueless, too, about accessories! I just bought my first filters!

Gordon - "I wasn't using anything specifc. Would that make a difference?"

I was just wondering as I noticed you were using 3 filters (1 rotating). The Cavision matte box lists 1 fixed and 1 rotating filter holder, and I was just curious on how and where additional filters go?

I used a Hoya ND4, 52mm filter followed by two Hoya 52mm circular polarizing filters, one of which was taped to stop it from rotating, and the other removed and flipped over in it's mount. When rotating the outer CP filter, you get a nice variable ND effect. All three filters were stacked up with the rotating CP on the outside, so I could rotate it freely.

So they are simply stacked 52mm ND and CP filters.

G,

nothing that indicates it's a "gray" ND filter?

ND is grey
 
ND filters are all supposed to be 'grey'. ND stands for Neutral Density. Neutral, as in no color tint effect. It should attenuate the full visible spectrum the same amount.

Then I wonder why they label it as grey. Weird...

Gordon Lupien Jr. January 16th, 2004 12:03 PM

Just checking, but none of this ND filter stuff has anything to do with the edge enhancement problem, right? There's no chance that using the incorrect filter will somehow "turn on" edge enhancement...

I'd be surprised...

How come no HD10 people are showing us any pictures????

I'll have some jpegs this weekend. Just been busy!

Gordon Lupien Jr. January 16th, 2004 06:20 PM

Thanks Heath! You're the man!

(special request...) Can you take some tape of something horizontal that's ever so slightly over-exposed so we can see if that's what the problem is?

Thanks a ton!!!

- GLupien

Heath McKnight January 16th, 2004 07:03 PM

Which problem? I'm so busy, I've lost track...

I won't have the camera as of Tuesday, so I'll try and do it ASAP. I'm loaning it to a friend for some potential work.

HD10 Shots
 
Here a few HD10 shots I did while running a few filter tests a month ago. The pics are compressed with jpeg compression so they look worse online and the chroma noise in the sky issue has been solved with various filter use and after effects. I don't know how to post a proper link in here so I'm just putting the address.

Sorry, I got the HD1 and HD10 confused. I'm assuming that having a touch of overexposure in the video is what causes the HD1 to go nuts on the edge enhancement. I did some analysis in Photoshop on my problem footage.

I'm wondering if you could overexpose a couple things in a shot or two with the HD10 so I can see what the edge enhancement does with it.
