Homebrew PCBs

But i still don't really know which advantage the dry (wet) film has.
May you lay out the advantages compared to presensitized boards?
As i understand it is only a method of applying photoresist?
The only advantage i see is when using rotary drum-like laser exposure 
plotter.
Sure it is good for something - you wouldn't use it if not... please tell 
me.

thanks..
