Making joint photo is not difficult. If you can make passport size photos then making joint photo is too easy. I am gonna tell you few step and I ma sure with these step you gonna about this stuff.
- Move to photoshop your destination both photos wich one you want to make joint. After tht first make it passport size..
- Making passport size photo is also easy. Crop it at 1.2 width and 1.5 height in inches. After that change the background using magic tool. In whole photoshop I like magic tool most because this help to change background in magic. You can make your photo as well as you can but both of photos background should be same.
- Now open a new page and drag both photos in that new page. Now fix it see what is perfect move. After that crop that photos at 2.1 inch width and height will 1.5 means same like passport size photo.
After that you can add border select all and go edit section and add strokes. Now go to layer and merge the both layer. Now finally move to again in new page and see how much pieces of photos you need..
