'Super 16' shoot.

Hey Guys,

I'm finally going to shoot 16mm test footage in the next couple of months. I am going to shoot it in day and night, outside.

I am going to use 'Kodak 500T 7219' 16mm stock with Ultra 16 lenses. Then, I will scan it in Arriscanner in 2k or 4k, in 2-flash HDR. Shutter will be 180 degree i.e. 1/48 at 24fps and few at 48, 60 or 72fps.

But, before I do, I need to know the following -

1. I need to know that is there going to be flicker issues at '1/48 or 180 degree shutter', when I am going to shoot under LED Street Lamps?

2. How should I scan the film, 'Faster or Slower'? And is 12 or 16 bit output in 2k or 4k, in ProRes 4444 XQ will be enough to get 'High Quality' image? What should be the Output Format/s without any quality loss? Also, log or linear output?

3. Ultra 16 lenses have a T-Stop of 1.3. Will I be able to capture 'Skyline' when I will be shooting at Night, especially when I am shooting on streets?

4. Do I need to push 16mm 500T film at T-Stop 1.3 by 1/2-stop or 1-stop to get that clear skyline? What will be the advantages and disadvantages of that?

5. What will I notice when I will scan it in 'Normal vs 2-flash HDR' scan? Especially, after pushing a film. How clean will be the image in the Night because of that? 'Grain issues'.

6. What T-stop I have to use when I am shooting 'daylight and early morning' sequences on 500T film? I am not going to use any filter on lens.

7. I have a MacBook MJY32HN/A with 8GB DDR3 1600MHz ram with Intel HD Graphics 5300. Is it good enough for handling 4k footage?

Thank you.

Wow, you have a lot going on here. However, you haven't mentioned what your goals are for the footage. The final delivery; whether going back to film or staying as video, presented as theatrical or internet, etc., what type of effects you are going to process the footage through, and so on.

But to address your questions here are some ideas;
1) You need to research what type of street lamps are in your neighborhood. The manufacturer will be able to provide specs. though you'll still need testing.
2) If you are scanning the film then consult your tech. The negative IS your log footage. Discuss your goals (see above) and they should be able to guide you. For format, I find that I like ProRES best but that depends on your editing system. But note that 4444 footage is large and will require a fair amount of fast storage.
3) Get yourself a spot meter. You can refer to the exposure index on the film and then compare your readings to how you want the sky to look. (read up on the gamma curve for film stocks and how to expose for the desired effect.)
4) Pushing film stock is a chemical process and affects the grain structure of your negative. I always shoot straight and allow the colorist/transfer tech adjust in the transfer. Why add another variable to the film processing step. You'll get better control of the grain and an overall better look.
5) Refer to #2
6) You are asking about exposure. Use your light meter. The morning sky is different in different parts of the world and at different times of the year. (Film school should have taught you that.)
7) Your computer is probably under powered. What's important is the processing speed, processing power, software being used, and storage speed and capacity. Remember that when you edit your system needs to be able to process more than one stream of your footage. (Use the Blackmagic Disk Speed Test tester for insight; see the apple app store) 4K will likely choke on your system either because of thru-put to the storage or processing speed. You should be able to edit in proxy mode but the final will likely require bigger and better hardware.

Hope this helps

Thank you very much, Sir. I will take this under consideration.

About the computer - you can probably make it work for straight editing by replacing the hard drive with an SSD, increasing the RAM to 16GB, and creating a proxy when you bring in the footage. This is how I handle 4K footage on a Mac Mini i7 with 3000 graphics, which is weaker than what you have. This machine handles final render running FCPX with no problem. If the film requires substantial effects work, you will need to send the work out, or get a more powerful computer.
If the problem is morning sky, you need only wait until the sky is bright enough, which is determined by the readings of the spot meter. Will the shot contain critical action? If so, budget three mornings. I have learned from bitter experience that shooting before shadows appear provides a very narrow time window.

In film school, I shot a lot of short films on 16mm. I'd advise doing the following things in preparation for principle photography:

1. Shoot test footage to get a true speed rating for the film stock. You'll have to work closely with your chosen lab to do so.

2. If possible, buy your film stock in bulk and split it off into rolls for whatever magazine size you'll be using. Doing so will enable you to get more consistent results.

3. Test all your equipment thoroughly if possible, including the lenses.

4. Choose an overall f-stop at which to shoot most of your footage. Many DPs like to shoot at f/4 for good depth of field.

5. Use lights with a high CRI (Color Rendering Index) rating, preferably 90 or above. These lights will be less lightly to flicker or hum. Also, use balanced electrical cables to avoid background hum, which can occur at 50 Hz or 60 Hz.

6. Get a good slate and a color chip chart. Datacolor makes a great color chip chart, the SpyderCHECKR (http://www.datacolor.com/photography-design/product-overview/spyder-chec...). You need the color chart at the head of each roll of film so that the lab will have a reference point.

7. Equip your computer with a dedicated graphics card. Macs usually come with AMD cards, which can be quite good. Check your NLE software for technical requirements.

8. It's best to have your OS drive, C drive, running off a solid state drive. That will reduce latency.

9. If your Macbook has a Thunderbolt 2 or 3 port, you can use an external hard drive that utilizes that throughput. G-Technology has some fast, reliable external drives.

10. Calibrate your Macbook monitor for proper color rendition during color corrections and grading.
