I have submitted two more images, strictly family album quality, for your perusal and comments.
These were taken on the following day to the first two images, same venue but at mid-day with a clearer, brighter sky.
These latter two images were not tweaked, simply converted from raw to jpg.
I maintained the camera settings from the previous day and they turned out much brighter and I feel a vast improvement was made.
I believe that the light being more overhead, reflected upward from the snow on the ground, was partly responsible and the other contributing factors,looking at the three untweaked shots, were the percentages of light to dark altered within each image allowing the camera more scope in it's autofocus system. Do you have any opinions on this?
If you had taken the same shots with your basic camera and again with your top of the range camera would you expect the same degree of variation in quality between the three images in each case?
