calibration

[Lee Kelly]

I have usually been quite careful to calibrate prior to my shoots and recently started to store different settings for different frame rates and resolutions that I use.

Do you need to go into that menu and choose the stored calibration setting or is there an automated, or even a custom button that will select a different calibration setting?

I recently went from 4khd 100fps to 2khd 240fps without selecting the calibration and the image was terrible. I was using the camera inside my water housing and could not access that calibration menu.

Thanks for the info.

you could set up hotkeys for it but no it does not go/chsnge automattically as long as you dont go weapon.

I found that on my dragon the best all around calibration if shooting mostly 180 degree shutter was ... 100-120 fps at 180degrees. One of those should keep things in the green or close to it for 24fps to 300fps.

Try one at 60fps 180 as well if 100-120 is not doing it.

im having problems with calibration on recent fw.
i did at least 10 different calibration and still getting this ugly line at 12800 ISO 100fps.Its very visible when i choose 6K WS mode.

Looks very clean Kemalettin.

as to the original post. You get 4 custom calibration slots with Epic Dragon. If you calibrate at let's say.

1/24th, 1/48th, 1/96, 1/98 then you will be covered for most shooting situations.

The calibrations are based on shutter speed, not the shutter angle and this can be confusing depending on whether you keep your epic in relative or absolute mode.

But the calibration sensor reacts or turns a color other than green if you are calibrated at say 1/24th and have the camera set to 1/48th. The further away you get form the calibration the more like your chances of seeing RED calibration.

Plus there are two sensors one for shutter speed and one for temperature, so the calibrations need to be done at the Shutter Speed and at sensor operating temperature.

Weapon has automatic calibration to some degree I believe

the automatic calibration on weapon is ok. But when you try to keep a 180 degree shutter throughout your frame rates, thats when it starts to go out of whack. I find having a shutter set to 1/72 for calibration works from 11-300fps at a 180 degree shutter. Also with WEAPON you have a + and - of 5 degrees in temp of the sensor calibration. With EPIC dragon it was 2 degree + or -.
