Need advice on techniques, methods, tools, etc. to fix the exposure problem in the photo below. I've triedseveral things without good results - masking and using levels, curves, burn tool, camera raw filter, etc. The attached image is in jpg format since I can't load a tiff format. Have provided a link to a tiff format on my Google drive if someone wants to experiment on the photo. I scanned it at 600dpi
