Problems syncing pics from Photos to iPhone 5s over iTunes

Hi!

I have some trouble syncing my pics from my iMac to my iPhone.

I used to download my pics to aperture and then from iTunes choose which pics had to be synced to my iPhone when using iTunes.

Now I had to download the latest iTunes (12.1.2.27) because of problems with aperture. The new version of of iTunes however did not like my older OS so I had to update to yosemite (10.10.3).

All well, but now aperture is not working any more !!!!! grrrrrrr!!!!

I started to use Photos from the new os, which is not that great but ok, it'll do for what I use my pics for.

BUT : Now when I want to sync my pics to my iPhone from Photos over iTunes it will only let me check the "All pictures and albums" mark !!!!!!! I don't want to have all my pics on my iPhone, just the selected albums like I did from aperture. (My library is way to big anyway : 313 GB)

Can anybody help me with this problem please ?

It all went so well with Aperture (Which I paid for for btw and can't use anymore!!!)

Thanks,

Tom
