This is the beginning of the source background removal.
step 2 of 10
Continued removal of the background.
step 3 of 10
Background is removed.This step and the last two utilized the pen tool and various eraser sizes and hardness.
step 4 of 10
This is a photo of a dairy farm I took in my old neighborhood.
step 5 of 10
I temporarily removed the large horse while placing the rest in the pasture and re-sizing them. I tried to use the size relationship between the horses and the dandelions to choose the best possible scale for them.
step 6 of 10
I dropped the larger horse into the picture. The background layer was duplicated and the area behind the horses was affected with a slight gaussian blur to hopefully improve the depth of field.
step 7 of 10
Further work was done on masked edges because there was a lot of residual green on them. The three middle horses were separated from the one in the rear because I didn't like the way the two white horses' backs were tangent. I relocated the rear horse to suit. The eraser tool was used at the feet of the horses with a standard grass brush tip to make the grass look natural in front of the feet.
step 8 of 10
I duplicated the large horse's layer and flipped it to start the shadow process.
step 9 of 10
Some additional shadow area was added to the large horse shadow, opacity was reduced to 43 percent, and some gaussian blur was applied. The center 3 horses were duplicated and mirrored for shadow creation to start.
step 10 of 10
Horse shadows were manipulated like the large one with some subtle differences. I used the skew function to distort the shadows and added some with a brush. The eraser with a grass brush was used to erase the front area of each shadow like there was tall grass blocking part of it.
