LR is my suggestion
I've been through the pain, over and over,
The pain started like this,
I bought a Nikon Digital SLR,
Bought Nikon Capture NX2,
Used that software for many years, became a very confident user and was getting the most out of the software
-Then Nikon decided to stop supporting the software
Bought Apple Aperture
-Then Apple decided not to support the software
Bought Adobe CC with Lightroom and Photoshop
happy now
All of the above sounds OK but there is a giant problem in the transition for every change that is made,
-all edits made in each software are gone and one has to re-edit every image unless files are changed over to tiff files
-When you end up with thousands of images this can be a nightmare
I suggest 2 options,
1. Buys Lightroom and at least download an ibook on how to use it, or
2. Get Adobe CC which gives you Lightroom and Photoshop, yes, it is a subscription, but at $9.95 a month, suits me
you will find the LR does almost everything you need, and importantly, will catalog your images as well
Plus, there is a mile of training on tube and Adobe TV
Lastly, if all of the above is not suitable,
and you have a Nikon, you can download all the software from NIKON for free
Nikon Capture NX2 is now replaced by Nikon Capture NXD, free software that will get you started for free, but remembering, down the track, if you decide to change software afterwards, you will have to re-edit or change to tiff files
If you have a Canon, like most big manufacturers, they all have some form of editing software paged with the camera
