A heads up for Lightroom 7.1 which came out overnight with updates to all parts of the "Lightroom world" - Lightroom 7 itself (the so-called "Classic"), and the LRCC apps on iOS, Android and PC/Mac. It's mainly camera support, bug fixes, performance tuning, but I recommend that you check out the new Auto button.
The old Auto always used to be a "lucky dip", wrong as often as it was right, but the calculation has been totally changed. It now also sets Vibrance and Saturation, which I don't completely like (I live in a drab country) but I can live with this. If I don't like the effect on the image, I just double click the Presence label, which is quick and convenient. As in the attached example (Lr6 on the left, Lr7 on the right) I think the new Auto almost always produces a substantially better starting point than the old Auto, usually that starting point is good, and in this example I would be happy with its Vibrance and Saturation settings. In general, I think the new Auto almost always produces a substantially better starting point and the improvement is significant enough to give it a try.
