Camera Tests

So after the less the optimal outcome of the 48 hour project as noted in the previous post, I decided we needed to recheck our findings on the Benito’s Camera. Mark, Benito and I met on Sunday to do just that.
First thing we had to do was establish the relative ASA value of the camera. We spent a bit more time on it this time around. We set up a Baby and lit a color chart mounted on a bounce card placed about 10 feet from the camera. The chart read about 65 Foot candles and then with a monitor, we adjusted the aperture until we could see the differences between the two white values without them bleeding over. This was a stop of 4.0. Then we did the math and came up with something between 200 and 220 ASA.
We then lit the room for a lighting test to and had the kid walk in to the scene, sit in the chair read for a bit and then get up and walk out of the shot. The look we were going for was that of the Beach house scenes in Reds. We found that these scenes had a natural feel to them where the DP lit the walls and if there were a practical used that for key. The actors would walk in and out of light. I really liked it and that is the look I am going for.
Se we set a Baby to light the far wall with a double net to add a bit of top shadow. In the practical we placed a 250 watt photo flood. Note the lame was way hot so we cut it down with two pieces of 251 diffusion and a piece of half straw. When we shoot I think we will use nd3 and trim it back so we get a bit of a rim off the spill from the practical. Finally we hung a China Ball with a 250 on a C stand just to the left of the camera to add a bit of volume to the room. She exits between the camera and the china ball. There is also a Bounce card to the right of the chair to fill her face.
We shot these using different Aperture settings from 2.8-8 as noted on the slate.
Here is the test footage. I think the focus is a bit soft, something Benito has to work on before we shoot, particularly in the wider shots. I prefer the look in the 5.6 take. The meters were reading about 2.8 on the Baby, and practical and about 2.0 for the fill

It'd almost be work if you didn't enjoy it so much . :-)

what kind of fill card did you use on her face?

was it silver or gold?

At 3:07 PM, Blogger Eric said...

Actually brat it was white foam core.
There was some straw gel in the practical behind her so that is probably what you are seeing cominb off the bounce card, which was located below her angled up on another chair camera right.
We also had her bring up the book to read to see how much fill came off of that.

Also you will notice a blue tinge on her camera right side.
That is because we have a Hugh Jass picture window in that direction that I covered with a blue tarp that adds that color and also a sort of sickly pallor to the fill. That will be corrected

wow, i never would have guessed it was white foam core.

did you guys do a meter reading for the wall and the chair? i'm wondering the difference between the two.

i'm just learning about lighting myself - these past two posts have been very helpful!

Yes we took readings on the Key, practical behind her and the 1 K baby that is lighting the wall.
I posted this on the myspace filmmakers forum and got a lot of great feedback since mark and I are film lighters and are still learning the tweaks for digital video.

I believe the baby was reading at about 2.8 and the practical was reading at about 3 the fill was reading at about 2.0.
But as it turns out from the myspace feedback that we got the rating wrong. That camera is usually about 300-350 ASA so we were off by a stop. So up everything 1 stop and you should have the actual values. Setting the exposure to 5.6 gave us the best look IMHO.
In two weeks we are going to test again with this new information but rather than ligting and changing exposures we are going to light for the exposure we want. Stay tuned

"Hey!", she said desperately trying to get her husband's attention, "That kid is reading HPVII!"

(See? I'm good at continuity).

Yes she is dear. Is that a problem?

At 8:35 AM, Blogger Lorraine said...

No, I'm just proving that I read your blog even when I don't understand what you're talking about.
