I have a raster file (.tiff format) such as the sample below and I was wondering how I could do a blend between the round lightgreen shape and the darkgreen shape in Photoshop (without affecting the other features -> blueish shape and beige shape)?
The final result will be a landuse layer of a map and will be draped over terrain information like this
The border of the round lightgreen shape isn't clear and therefore should slowly blend into the darkgreen shape. How could I achieve this effect in Photoshop? I tried using the Smudge Tool, this partly works, but a uniform blend would be best.
I tried to use ACEkin's answer and separated each shape to a different layer by using the Magic Wand Tool, selecting the shape and then right click "Layer by Copy". Then in the layer panel, I clicked on the separated layer with the lightgreen round shape and selected the shape with the magic wand tool. I did a right click and feathered the shape by 5 pixels and then again right clicked and "Layer by Cut". I then turned of the created layer and have the ghost area as you described. My image now looks like this.
However I am not sure how to proceed next. I don't really understand the step with the clone tool.
In the end I am looking for a result to achieve a gradual blend between the lightgreen and the darkgreen shapes, the river etc. doesn't need to have a blend as its borders are clear.
Here you can find the .psd file for my project.
