I am a hobbyist photographer, and I am considering buying Adobe Lightroom. Do you guys think that Lightroom is necessary for someone who shoots in RAW with the Nikon D3200? I shoot fairly often, but photography is just a hobby for me. Thanks.
I would definitely recommend getting it, but you might want to wait a month or two... Usually close to the launch of the new lightroom you can find it for 60 or 70$.... If you time it right, within 30 days of the official launch you can even get adobe to upgrade you to the newest one. As mentioned in another comment, use the trial and learn how the program works... There are tons of free resources and videos to help you figure it out.
Just to add:
You can get darktable for FREE, and it does most of what you'll need for RAW editing, including some very advanced features.
So is Lightroom necessary for a hobbyist? given darktable's capabilities, I'd say the answer is a no.
Definitely recommend buying Adobe Lightroom, it is a lot easier to get used to than Photoshop CS6 and helps organise your photo library very well. I would either recommend you go for Lightroom or Photoshop Elements, both are great for editing to suit the amateur photographer. Furthermore all Adobe software has a strong community, with plenty of tutorials to help you as well as information around the internet.
