I have the following image, and I would like to apply motion blur to the water.
I applied motion blur to the whole image and then masked out the subject:
I tried to apply a lighter mask around the horses' feet, and the results came out quite poorly:
Then it occurred to me that I want more motion blur the further away I am from my subject. This means I want a small degree of motion around the horse and a high degree of motion away from the horse.
Is this possible with photoshop? If there is another type of blur that can achieve this effect please let me know.
