When I load my photo files to LR5, they look fine in Library mode. However when I want to open them in Develop an unwanted preset is applied. I have tried to reset the photos but then when I want to edit them the preset reappears. I have tried changing the 1st photo and syncing the rest but again, the preset reappears. Please help me!!!!!
Make all the settings you want as the Default then go to the Develop menu item then the "Set default settings" item.
If you want everything at zero set that then as above.
I'll try from another angle. What makes you believe a preset is being applied? Do you see a preset listed in the history panel?
Yes I can see it listed in history and I can see the pictures change. If I scroll on a picture, the next 5 or 6 change without me touching them.
