Blending

1) Open two or more images that you are going to blend on photoshop, making sure that they have similar backgrounds to make the blend look more realistic, also at this point you may want to overlap them to make the process easier

2) Select the rectangular marquee tool.......
3) And set the feathering at 35px
4) Now with the marquee tool select the part you want to take away, and there should be a dotted line around it like so but when doing this part make sure your deleting the correct layer (viewed in layers tab)
5) Now once selected press delete until desired image is shown
6) Now you have a blend!
