i did this to alter the green colour cast. using the black wh and grey markers to adjust. i cropped it to show a different composition where the caterpillar is less central, but had to extend the border.
first i adjusted the exposure with curves so the shadows become darker and midtones stronger. cropped on the right and top to balance the composition. finally i cloned out a few distracting highlights.
some more shots of feeding time that did'nt make the grade but this gives more of a film like view of the process. 3 images pasted onto a black background.
