To photo or not to photo.
Do it like Bob, just enjoy photography
A camera with a so called kit lens (the one that comes with the camera), a RAW converter and a computer is all you need to start. Depending on your needs and expectations you should calculate with something like 500 Euros to start (you might even get it cheaper if you go for a used camera/ lens and/ or use a free RAW converter). Don't spend too much to start, as a beginner that would be wasted money since you don't know yet what exactly you will need in the future when your skills will have improved. And you cannot really buy into it, no matter how expensive your gear is, you still need to learn the basics and improve from there.
One last tip: I would not get Photoshop in order to start. I for example don't like edited photos, I want them as original as possible. All I do from time to time is removing a small detail that should not be there, that can easily be done with GIMP, a free and open source alternative to Photoshop. Later on if/ when you decide that you actually want to heavily edit your photos you can still get Photoshop.
I cant be agree with you on this! Photoshop can be a better choice for editing photos if someone is comfortable with it. I am using it and totally satisfied for any kind of editing task including removing the background!
