Practice is the best way to learn. I don't think I've ever watched a tutorial on LR, I've just experimented for about a year and a half and now I'm pretty resourceful with the program.
DON'T get presets like the VSCO presets. They are cheap, played, and amateur ways to creating a look that "seems" good but it really isn't.
I don't use LR much to organize photos very much, mainly just for editing. Here are some of the things I always edit while in the "Develop" tab:
- Exposure
- Contrast
- Tone Curve
- Colors - Playing with the Hue, Saturation, and Lightness helps simplify an image and highlight a specific subject and make the image the least distracting.
- Lens Corrections - Both profile corrections and chromatic aberration
- Noise - I shoot with a T3i so my shots are usually a little more noisy than the higher level cameras, so I usually bump the Luminance slider up to about 20
Sometimes I also play around with a graduated/gradient filter, especially to bring out the contrast of a ski or something of that sort.
I think that's it, let me know if you have any questions, I think I'm familiar enough with the program to help out.
