Just thinking out loud here…I haven't followed all the different releases of the BTC so I may be off, but did the newest released version (slower trigger time) eliminate the whiteout problems, or had that already been corrected?
Reason I ask is that I had a particular homebrew (a503) that would tend to get slightly washed out pictures when in an open sunny area on the first picture of a series, but normal pics on all subsequent pics (camera would remain on). The reason for this was that the camera needed time to adjust its aperture to limit the amount of light coming in, and it wasn't fully adjusted when the first picture was taken but was for all subsequent pics. I could have eliminated this by slowing the trigger speed by a few tenths of a second but never did because the wash outs weren't all that bad.
Now I don't believe the BTC has an adjustable aperture like a point and shoot camera, but I would think the firmware would have to account for the amount of light present. Perhaps it is similar in the fact it needs a certain amount of time for the camera to adjust before taking a picture?
My whole point to this rambling…is it possible that bushnell was forced to sacrifice the trigger speed in order to eliminate the whiteouts?
In theory what you are saying is true. If a particular camera uses light metering, then it is sampling the light with the sensor and adjusting the photo/video imaging properties prior to captureing/saving the final image to the SD card. Not all cameras have light metering. Light metering is a dynamic process that can take more or less time depending on light conditions, thus trigger times are essentially affected. I would say that 500ms or .5 seconds is more than enough time to do this portion so I guestimate that only .5 second of a trigger time should be attributed to light metering unless sloppy programming is done in the firmware. Light metering is required to properly avoid whiteout at dusk and dawn.
On the Trophycams we are seeing extra seconds, not .5 seconds so something else is happening here.
We do know that hardware changes were made to the boards inside the TrophyCams in the May time frame and that firmware changes were required to support the new chips. What this entailed we do not know. We guestimate that poor firmware coding could be attributable to some of the trigger time losses and that some is hardware which may not be correctable.
