Can you Use Ease in out on Scale keyframes?

Im trying to have a picture come off the screen and get smaller as if a picture was taken and then gets bigger zooming out again but id like to have it ease in and out at the getting smaller part before it comes zooming back out. I know you can do that on position but i don't see it for scaling. any ideas other than going to motion.
Thanks

Not quite sure what you mean but have you tried the Ken Burns option in the crop tool?

With moving a picture you have ease in and out adjustments or making a key frame not be linier, u can have a curve ( can't remember what its called, something like bezier.)
lets you slow in down at the key frame giving it a smooth motion But i don't have that with Scale keyframes. i did try the ken burns but i didn't see any adjustments for it.
