Rather nice transparency at 6/10, seeing 1/10 as created by the wind....
Reducer lens always inside the BF10 unless stated explicitly.
First up is an image taken with ROI feature, frame rate goes up to over 40 fps, but given the very poor seeing, it does not help much. Taken at 1433 (GMT+8):-
This is what it called "skip" mode, full resolution is not used by skipping some pixels, which results in higher frame rate, but with the same field of view.
By using full resolution, the frame rate is lower and as you will see from below, the image is blurred far more by seeing.
So now the "skip" mode is even more useful than ROI.
I found that ROI is not well implemented by SharpCap, it is not user friendly at all, one should be able to draw the ROI on screen instead of setting offset and the frame size!
