I know there are pro logo designers out there who almost always use
Photoshop for their work.
This software is not cheap but there is an equivalent which is called Gimp
and is free.
I know that it is not as good as PS but it can do almost everything what PS can do.
I just tried some of the free Gimp logo design tutorials on youtube and I simply imitated every step there, the result was not bad for me.
But what I ask myself is if there is really anyone out here who uses Gimp to make real pro logos? Can you show some of them? Or do you know a good tutorial how to make one?
