In the library module select Capture time as the Sort option.
I can't find that Capture time box. But the library isn't messed up - the import dialogue when the card is connected is all out of order.
Sorry I should have clarified.
I tried making a correctly marked folder to guide the images in the lightroom library to. But when I click "reveal in finder" they show as on my card. When I try to import images from the folder I created, they all get greyed out and it won't let me.
Do I have to delete my original images and reimport them from the correct created folder?
Slow down. When you import images in the import dialog there is an option at the bottom for the Sort of the files. You have something other than Capture time selected. That is why the images Look Out Of Order in the import dialog. It doesn't really matter how they are sorted in the import dialog unless you want to exclude some images and finding those is easier when they are sorted by Capture Time.
Once images are imported into LR you can't Re-Import those same images. That is why they are greyed out, they are already in the catalog.
As to creating folders for your images on import that is all User Selectable in the right hand area of the import dialog window.
Thanks that solves it!
