You have a very good eye Helen. The photo of the swans is a vintage photo and came in B&W. I felt it was a bit pale and faded so I duplicated it and did some blending to darken it. I merged both layers together and then selected some of the white areas of the swan and lightened them to try and emphasise the white. The kit I used has a definite vintage look to it. I converted the pieces I used to B&W blending two different BG’s together with a soft light blend mode. The leaves were shades of a dark green to start with so they converted easily to B&W to give the look you see.
The image of the Swan and Ducks is apparently from an antique children’s storybook titled ‘Visit to the Farm’ by Koerner & Hayes 1896 and can be found here if you would like it. There is a coloured version as well as the B&W.
