The natural tool for digital manipulation always seems to be Photoshop (or Adobe Photoshop to be more specific).  I had to do a photo project, taking pictures of an event and doing simple modifications to 30 photos turned out to be very meticulous!  Instead of using Photoshop, I decided to use something I was much less familiar with, yet perfect for the job at hand.  I used Lightroom because it gave me the opportunity to modify one picture and copy the effects onto each picture with similar lighting and contrast.  It was very successful at creating the changes I needed!
