Simulating Bleach-Bypass with HD
Posted 21 December 2006 - 06:36 PM
Very excited, my first posting...
I´m an aspiring DP and shooting my first short film in Februar. We have a little money from the film fund here in Berlin, but it´s still a very low- or even no-budget production. first of all, a little information, before I start with the questions:
1. the film plays entirely in a hospital, 11 night scenes, 5 day scenes. we´re shooting in winter in Berlin, which means that we would use lamps to simulate the day light. (the story plays in the middle east... another small challenge.)
2. we´re shooting with the panasonic HVX200 and the P&S 35 Adaptor.
3. I want to simulate a bleach-bypass in the post production, so basically I want to create a black and white image on top of the color image, and mix them with layers-modes. (I still don´t have a colorist, maybe he´ll have better technics) I´m aiming for a gentle BB look, not really all the way like "Saving private Ryan", maybe something like "se7en", maybe a little gentler.
4. we´re aiming for a 35mm Blow-up at the end.
and now, for the questions:
1. with BB-process in film, you usually should under-expose by about 1 stop, to create a softer negative. I did a little tests with photoshop, and I´m having a problem with the shadows, more than with the highlights. does it mean that with HD I should over-expose? (it´s actually like a positive, so it makes sense)
2. also, the lighting, even with film, should be very soft. now, that scares me a little, because HD is anyway not very tolerant for many f-stops. If I´m going for BB, does it mean that I should light my sets really really soft and without contrast? I like to light a little harder, even with video... should I really avoid it? what I´m asking is, am I going for very soft and balanced shots, or am I allowed to "let it burn"?
3. If I know now that I´m going to make a bleach bypass, and I want to go for a look that´s a little dirty with high contrast and little saturation, can I save a little money and shoot with HDV? (We can have a sony Z1 for free, or a HVX200 from rental) the production design could use the extra money, but since we want a blow-up I thought I should stick with the pure HD, progressive scan.
I thank you a lot in advance for the response, if anyone has any experience with HD and BB I would be happy to hear stories, ideas and conclusions. It´s not only my first film, I also wrote the script and it´s very important to me that it works... like for all of us.

Unfortunately I'm not knowledgable about how you should light a scene for bleach bypass. It really just depends on what you want with your bleach bypass. I know in Minority Report a lot of it was way overexposed, and that was the look that Spielberg wanted. It really just depends.

Definitely go with the HVX; the extra color information is going to make a big difference when you're playing with the colors.
I'm wondering, though, if you'll really be able to afford a filmout. It's really expensive to do, and if your budget is such that you're deciding between an HVX and a Z1, you would probably have difficulty fitting it in.
Consider also that those 35 adaptors tend to soften the image a lot, you lose most high-frequency detail because of all of the extra glass. I don't know how well it's all going to hold up when printed to 35mm.
