Ltl Acorn 6210 daylight still image under exposure

Fig 1:  6210 Image with under exposed foreground.
During my time away I lent a recent 6210MMX to a member of a UK squirrel group who are monitoring for Gray Squirrel incursion into a sensitive Red Squirrel population. The purpose was to test the cameras ability to send emails by SMTP (see tomorrows post for the results).

During the tests a daylight exposure issue was highlighted which I have illustrated here. Figures 1 and 3 are the images sent by email, where the important detail is almost invisible due to under exposure. Figures 2 and 4 are the first frames of the video following each image and are correctly

Fig 3:  6210 image with under exposed foreground.
The metering mode is centre weighted average which should produce an acceptable balance between background and foreground, as is seen in the videos.

I would be grateful to hear from any users who have had similar results and am contacting the manufacturers to see if firmware can be made available to correct this.

This web site is about the wildlife, particularly the mammals, of the Glen Affric National Nature Reserve area in the north west Highlands of Scotland, UK; and the equipment I use to search for them, which is chiefly trail cameras.

I provide a technical support and parts service for the Ltl Acorn range of cameras and the income from this provides for the upkeep of this site and the purchase of cameras for my own surveying.

I hope you find the site useful and informative; and please contact me if you have any questions that I haven't already covered.
