Help error with auto blend

[jason520]

This error happened when i auto blend two layer, i need help, thank you

 

[colleague]

the 2 layers for auto blend have to overlap a few pixels
look into this tut where they modify the selection for this purpose

I did the same steps, use inverse or select contract, but this error happened all the time

 

[colleague]

the edges of the selection are too sharp , can you feather the selection 5 pixels ?
and overlap the layers 10 pixels

maybe you can try this PSD , but I did not have the originals
after the blending it's possible that you have to clean up the result with cloon- tool

After select contract to 30, and feather 5, two pic blend perfectly, dont know how, thank you mr guru
