Ive been using LR 3 for a couple of years and upgraded to LR 4. On the whole im very happy with the improvements, but have made a gaff that im now regretting.
LR 4 uses new processing algorithms and when you open an image in develop mode it asks you if you want to reprocess using the new ones. being a progressive sort of dude i clicked on yes, it then asked if i wanted to apply this to all of my images and so i clicked yes......
Whilst it made very little difference to the colour images, all of my black and white stuff was re processed into a grey washed out mess . OK i can go back in the history and revert back to the original edits but i have to do that on an individual basis.
does anyone know how to reverse this global process?
from now on my default place will be "just say NO" until i totally understand how the change will work. Lesson learned.
