I've been using Rawtherapee to develop my Nikon D3200's .NEF raw files for a few months now, but I've never quite got the same results as the off the camera jpegs. That is until now!
I've decided to bite the bullet and spend some time trying my best to create a profile within Rawtherapee that most closely approximates the great results I get straight from the camera on properly exposed photos. So here are my results (click for full resolution 6000x4000):
First the camera processed jpeg (top) vs Rawtherapee's "Default" (bottom) profile:
The camera processed jpeg (top) vs my best attempt (bottom):
The camera processed jpeg (top) vs the my profile plus some tone mapping (bottom):
Below is the contents of the pp3 file (wordpress won't allow for non media files to be uploaded...). You must change the "LCPFile=" parameters (I've highlighted it in red) to fit the directory where you keep your lens correction files.
