Hi Peter. I'm not sure which processes you're curious about so I'll give a quick overview.
The objective was to turn a gloomy day into a sunny day. The main difference between gloomy and sunny is direct sunshine - which is yellow - so one of the first things I did was to shift the white balance well towards yellow (I settled for 15 on the Lighroom WB slider). I also shifted the Tint slider towards magenta a little (+5) to add a touch of warmth to the sunshine.
When an image needs an overall boost, the two obvious things to try are increasing Contrast (or a mixture of Contrast and Clarity) and increasing Saturation (or a mixture of Vibrance and Saturation). In the case of global adjustments (those that are applied to the whole image), there are two possible approaches. One approach is to ramp up the adjustment until parts of the image start to show undesirable effects (overcooking) and then back off slightly. Another approach is to deliberately ramp up the adjustment beyond that point, then mitigate the negative unwanted effects of the over-adjusting, while keeping the positive desirable effects. Typically the negative effects will manifest only in limited areas while much of the image may respond positively to the adjustment.
The advantage of the second method is that you can push adjustments much further than you can with the first method - but you have to be able to mitigate the negative effects of over-pushing.
In the case of saturation, my current approach is to push Vibrance up quite high (60 or so in Lightroom) and then use the HSL tool to mitigate any unwanted effects. Red, orange, yellow and yellow/green are the most prone to becoming garish when ramped up (yellow/green is a common colour for vegetation, including grass). Colours can also become too solid and heavy, and that can happen not just through being over-saturated - it can also happen if they are darkened too much (darkening a colour strengthens it whereas lightening a colour weakens it). The HSL tool can lighten/darken and saturate/desaturate individual colours (it can also tint-shift colours). Once I've gone over the image with the HSL tool I'll return to the main edit to see if it needs any more tweaking. The quickest way to do that is to nudge the Saturation slider in the desired direction.
In the case of contrast, the negative effects of over-pushing can be countered using the Whites, Highlights, Brightness, Shadows and Blacks sliders. Ramping up Contrast or Clarity often results in blacks that are too solid and highlights that are too harsh (or blown). Alternatively, lowering the Whites/Highlights too much or lifting the Blacks/Shadows too much can leave an image looking flat and lacking in contrast. The optimum mixture typically depends on a delicate balance between darkness, brightness and contrast.
Increasing contrast also tends to strengthen colours, so it's a good idea to work on contrast before saturation.
The other steps that I took for the above image included cloning over problem areas that weren't responding well to the usual treatments. I also occasionally use the Adjustments brush and the Split Toning tool to add tints.
I hope this helps. If there is something specific that you want to know, feel free to ask.
