This is a photo of Downtown Los Angeles……well……it could be a bit boring. So, I decided to draw some cloud on the sky.
At first, I tried to draw clouds above the building…..but, it did not look that good. I found It is better to have clouds “behind those buildings!.
So, I decided to remove the original sky. Due to the clear (& boring) sky, “Magic eraser” worked very good.
Then, I made a new layer under the photo and gave some gradient to make it look like sky.
Now, install another layer between building and sky. That is where I made some cloud.
