Y’all asked to add an animal into the image, and to make things even a bit more difficult we decided to add a cat into the foreground.
First, we found an image of a cat that works for the photograph. You can take your own image as long as you remember to Light it all the same. We made a selection around the cat using the Magic Wand Tool, and with the Outline selected all we have to do is fill in the middle to make a quick, easy, and perfect selection. In order to make the cat seem natural we then use a combination of Levels, Hue, and Saturation to make sure we get the Color right. And we use a few special techniques to check the values of each. And finally a custom Brush with the Clone Stamp tool to add more grass in front of the cat.
Hope you all enjoy and can put this all in to practice soon!
