I looked at all three as thumbnails and the 2nd and 3rd stood out as more vibrant. Sometimes this is an illusion and viewing the full picture reveals this to be an illusion. However I still feel that pictures 2 and 3 are more vibrant. Better skintones and maybe more contrast? Of course as these aren't scans of prints but scans of negs, it may be that as prints there would be nothing to distinguish all three.
All are good but I am drawn to pics 2 and 3 purely on my perception of their vibrancy. Was there any difference on contrast in the neg?
Thank you George. As I remember (pictures taken 30 years ago) it was winter and cloudy day. Difference in contrast is probably due to altering light conditions. Clouds were playing with the sun. These three pictures were taken at the same time.
