Notes (to self):
Catalog - Restricted to one open at a time; holds all linked files.
Files remain non-destructive.

Move files/folders within Lightroom to avoid unlinked resource issues.
Retain original file name and track through keywords, ratings, picking and colour labels.
Use broad descriptive keywords on import: seasons, night, landscape and specific labels, to locate images when reviewing or editing.
Use Year-month-day - event format for folder creation.
If catalog becomes slow to use/search, use optimization feature.

Workflow practices developed:
Import images, name folder using convention, add broad labels;
Review images and add specific keywords, colour code, rate or pick selected images;

Identify image for adjustment, create a virtual copy (not required); and
In development, select Tone>Auto and review how L/room processes.
Adjust lens corrections, chromatic aberration, crop and profile correct as required. 

Adjust settings to suit the images purpose:

Exposure - Adjust the overall light/dark of image;

Highlights - Adjust detail of the bright areas only;

Shadows - Adjust detail of the dark areas only;

White/Black - Adjust the extreme points to avoid blocky areas (Alt + slider assists greatly);

Clarity - Defines edges and good for landscapes, especially if blurry. Avoid use of people as it can highlight unwanted features;

Contrast - Adjusts available differences between the light and dark areas. Good for foggy/hazy images but using may require additional adjustments to exposure, highlights and shadows;

Vibrance - Mostly used to effect the pop of an image by adjusting overall colour;

Temperature - Adjust the level of cool and heat viewed in an image, blue more cool, yellow more warmth;

Tint - Adjust the green/magenta balance of an image.

White balance picker - Find a neutral area (white, grey, black), move the picker until the RGB values are as equal as possible +- 0.1 - ie: R 92.5, G 92.4, B 92.5 and click done.

Other tools: Adjust image on a gradient or on a circle using other tools. Useful to highlight/reduce specific areas.

Hue: The specific colour, within a group of colours. Adjusting the hue will change the colour for another colour within the same group. (Red - Pink, Green - Yellow).

Saturation: The power of the colour. for example at the apposing ends of green are Bright Green and Green Grey.

Luminescence: How bright or dull a colour is.

Details: Adjust to sharpen image and reduce any noise produced. Excessive amount can cause unnatural results.

Export: Set up x2 JPEG export presets for future use.
