Lightroom User Tips
I think one of the best general purpose digital post processing tools that a photographer can use is Adobe LR. I receive nothing free from Adobe, but I do like the tool. It is much easier to learn than Photoshop.

Here are a couple of pointers that may be useful to new LR users to check out:

Presets: Adobe gives you some, but if you find your self doing similar types of edits on photos you can create your own presets. Go to the Develop Preset panel (on the left side) and click the Create New Preset icon (top & right of the word “Presets”). This brings up the Preset window, choose select none, and then check only the specific items you want to save. Once save you can easily apply these to any new images, or a group of photos.

Adjustment Brush: This lets you apply specific changes to only a small portion of the image. Think of it as a Photoshop mask, without having to use a lot of layers. Layers are a good think in Photoshop, because you can turn on and off many changes with out affecting the base image. LR doesn’t break out the changes as layers, but you have the ability to make many small changes to different areas.

Clone / Heal: This tool will allow you to replace imperfections one of two ways. The clone option blends in pixels from the surrounding are, to hide some small unwanted blemish or object in the image. Clone basically replaces pixels with those from another area, but either one can remove something unwanted or a distraction from the image.

Lens / Camera Calibration: This is an area where you have a lot more options when shooting RAW images. LR has many automatic correction for most Nikon and Canon lenses, and well as camera profiles that can be applied to make the image look more natural by correcting wide angle distortion, or have the colors look more like the standard Nikon D2X.

Copyright Metadata Preset: If some of the meta data like copy right information is missing, you can use this to add it and apply it to multiple images.
