I am new to this forum and have a rudimentary query. I have two images of the same scenery, one colored and one black and white. I want to merge the two photos so that the final photo contains one half of the colored image and the other half the black and white photo. The transition from color to black and white should be smooth.
I think this is already done in many software but I don't know the name of this effect. Further are there any online editing website where this feature is available.
