If you change 'particles', then the chosen 'filter' is removed automatically, so you cannot choose both; is that correct? Because I am within the test enviromnent (not paid version) so I want to try everything before buying, but I cannot change both... Also I cannot test eg make-uptool, or blur/change background; so I can not know beforehand what I will get as a result? I cannot really try the software unless I buy it first, then; right? Thx.
