okay photo friends this is how you make a photo booth strip in lightroom
select 4 images that you want in the strip
then click on the "print" mod
right under the print tab select contact sheet/ grid from the layout menu
on the left hand side of your screen under the templates select 4 Wide
back on the right hand side select zoom to fill * you can move the images around (with in its block) by click and drag.
now play around with your cell height and width until you get it the way you like
i used 2.36 for H
and 2.17 for W
NOW "print to file" to do this you need to scroll all the way down on the rt side, under print job select jpeg under the drop down menu. when you do this the bottom rt button changes from print to print to file....so now just print to file AKA "save as"
last but not least re-import the file and crop it down to size.
There! now you have yourself a cute little photo booth strip....the easy way!
