Contrast Range
Dealing with extremes of light

The sky was a good enough reason to take this picture, but I wanted to show the field, garden and Max too.

A second picture, taken with a longer exposure time, revealed the missing subjects but washed out that lovely sky. The solution was to use a combination of both images, which fortunately were similarly framed.

In Corel PHOTO-PAINT (TM) I pasted the second image over the first and aligned them carefully, by temporarily setting the opacity to 50% then rotating/scaling the pasted image (which therefore ought to be the "less important" one!) until the double-vision effect disappeared. Then I combined the images with the transparency tool on a linear blend path as shown, to produce a colourful but rather unnatural-looking picture.

Having compressed both the bright sky image and the dark ground image (gamma values 1.7 and 0.7 respectively applied), I used this elliptical blend path to get a more plausible result.
