Hi David Georges
Please follow the below mentioned link as you can downgrade to photoshop photography program and check the FAQ's under "Photoshop Photography Program Offer":
Let us know if that helps!
It seems that the answer is yes... but how to downgrade ?
Welcome to Adobe Forum,
It can be done in two ways.
A. Go to www.adobe.com, buy the photography CC, get the existing CC canceled without any cancellation fee (by contacting Adobe)
B.You can contact Adobe & change the Adobe CC plan. You can select it from :http://www.adobe.com/products/creativecloud-select-plan.html
To contact Adobe Support: http://adobe.ly/yxj0t6
In both cases, to start the photography CC, you need to just just log out & log back in of the CC desktop App.
