Here is one of my recently edited images, using a painting technique from another magazine!!!
you first open the image, then create a new canvas
paint it white
reduce opacity to 85%
then using the oil paint history brush and long straight stokes paint in main details,
change to short curly for sky and sea
create background copy layer and turn off other layers
use filter stylize-find edges
drop saturation to -100
over lay and use blending mode, i had to reduce this to about 80% as well.
then added signature and title using text tool. the flattened image.
hope you like the effect.
