Super slowmo question.

[Minu Park]

Hmm, I just moved into RED from Sony.

I was wondering, whether I need to black shading calibration all the time, when I shoot slow motion…. from 24 fps.

As a documentary film maker, keep the time is worth more than gold… It's just doesn't come to me.

Some says I could save calibration data into the SSD and read it when I need to. In that case, don't I need to wait this god damn 30min?

If I need to calibrate the sensor all the time, is there any tip that the new bid red owner to use super slow mo?

You can store 3 I believe, then it's just a simple select which one and shoot . I'm yet to do it on my dragon but there's many threads on it on here if you try a search you should find them

This is becoming more and more of an issue with Dragon on the documentary type shoots. Yes, you can save 4 presets but it still takes time to load them up every time you change exposure.
Best work around is to save 4 presets with exposures your work with the most. It may not help you miss the magic moment but it's the fastest way to get there in a hurry.

Also I've ignored black shading when changing stuff around.. from 25 to 200fps.. and it hadn't bothered me the slightest. So if there's a shot you must have than I say forget black shading and shoot

I shoot a lot of racing, so there is no time to black shade. What I do is run blackshading the day before at various shutter speeds: 1/48 - for shooting 23.98fps, 1/500 for shooting 120fps and then 1/1200 for shooting at 240fps. I save each calibration to the card and then back up the calibration folder onto my desktop of my laptop. When I ingest the card, I put it back in camera, reformat, put back into card reader and load the "calibration" folder onto freshly formatted card. When I am in the middle of shooting I can jump between various cals in a matter of 15 seconds. Its a life saver.

One note on the above process- I have my camera set to adaptive fans to keep the sensor at 65 degrees. This keeps everything happy and the calibrations within range to reduce noise.

Hope that helps.

DC this is Superb! Where is the cal map folder located once its saved onto the card for copying over onto a PC from a reader?

Craig-

It creates a folder in the root of the SSD named "calibrations." Drag that whole folder off the card an onto your desktop. Copy entire folder into root of formatted SSD and shoot. When you are changing shutter speed, go to the menu as if you are going to blackshade and then load the file that corresponds to your exposure time. done and done.

just a reminder Blackshading doesn't care about framerate at all, it's all about shutter speed

100% agree. Have yet to regret not black shading when switching fps.
