I'm not sure how to add filters to texts. I tried tutorials, but it wouldnt work. What I mean, is I want to be able to use the filters, and the filter gallery, but I don't know how, because it doesn't allow me to with just the texts.
#1
You have to rasterize the text (ie turn it into pixels) to use the filters but it won't be editable as text after that.
#2
Go to Layer>Rasterize>Type and rasterize the type...at type sizes about 18-24 pixels the rasterization will be almost unnoticible..smaller type however will show some jaggie edges...
Also you can create a type layer duplicate it and then rasterize the duplicate to save a copy of "editable text" in case you find typos,have a client change their mind, etc.
You could also try "layer styles" (double click on the blue area of a layer) not as dramatic as filters, but you can apply these and the text remains editable.
