Jerry being all over the map is a bad thing, it will lead to less than ideal processing and usually doing too much of the wrong things to an image. The very first thing you should do on opening an image is ask yourself what is wrong with it if anything? then you need a plan on how you intend to fix the image. In your case image over exposed,sky too light, low contrast, one side of street too light, some whites blown out, etc. What could fix this? Change WB, change Picture control. Low exposure, set B&W points, adjust curves, etc. CNX2 is set up to lead you down a path that starts with global adjustments to very specific and selective edits. This is the path you want to follow. Often a few preliminary steps will make the image perfect and you are done. Playing with curves, etc before you have set W &B points is counter productive. As you progress in the use of the tools you will learn which ones will give you the results you want.
