Hi there.
When calibrating our Panasonic AW-UE100 we run into issues at higher zoom levels (0.8 and above).
While the calibration process worked just fine at 0.2-0.6,
we had to switch to the smaller pattern when the Calibrator asked us to do so,
due to limitations in room size.
The first odd thing (which sort of happened at other zoom levels as well, but was bearable)
is the fact that at he 'Set your focus to the board'-stage of the process,
the sharpness indicator was hard to convince to come up into the yellow range.
Once we we had it within yellow and were allowed to press 'next',
the indicator went fully green, indicating maximum sharpness.
Feels as if two different algo's are used in 'set your focus' and all subsequent stages.
The second odd thing is, that at one point the grey region we are supposed to place the camera in,
became very small, making it literally impossible to place the camera (or the board) in a way
that would allow us to press the highly desired 'next' button.
In fact we had to cancel the calibration process at those higher stages.
The best we could get were *two* arrows on the camera pointing toward and away from the target at the same time.
Cheers & all the best.
Eric.
Hi Eric,
Thank you very much for the feedback. Note that we actively work on the camera calibrator and feedback like this helps a lot in making it even more user-friendly.
Sadly it might be that the yellow sharpness indicator is the best you can reach based on your zoom, camera, lens, etc... Nevertheless, you should try to set the focus as good as possible on the sharpness indicator.
As you should not change the focus in the subsequent stages, the calibrator makes the sharpness indicator more lenient in the next stage. Hopefully, this discourages people from changing their focus. And this is why it turned green for you.
The smaller pattern is meant to prevent cases like yours where there is very little correct position where you can place your camera. Small studio size is one of the reasons why this happens.
There are two possible reasons why you couldn't progress at the end:
You couldn't get far away that the smaller pattern fills the full image.
Or the image wasn't sharp enough. In this case, you could try it with smaller aperture size. Note that the calibrator works fairly well with dark images as long the image is evenly lit.
Can you give us how big of an area you worked on (length) and with what kind of lens? This may help us to further improve the calibrator in the future.
Warmest regards,
