.txt file information

Robin

In the.txt file that accompanies an image, there's a data field that gives Total Exposure(s). What is this?

In a recent image, the file indicated 4 second exposure, 14 stacked frames, and Total Exposure(s) of 5.993

Hi John,

it's supposed to be the total exposure time of all the frames that make up the stack, but that doesn't fit with the figures you are quoting. Can you share the whole contents of the txt file for me please.

cheers,

Robin

Ah, ok, found the bug. It affects DirectShow cameras and Webcams only.

It will be fixed in 3.1 - for now, trust the number of frames and the exposure per frame rather than the total exposure.

cheers,

Robin
