When do I check Don’t Import Suspected Duplicates?
It’s good practice to keep this section checked all the time. Especially if you upload different images from the same source, it helps to make sure you aren’t working on the same image twice. Lightroom determines duplicates by name, file size, and time stamp (+/- 1 minute).


When do I use Make a Second Copy To:?
Making a second copy is a quick way to create back-up images. If you import directly from your card often, and erase/format your card after importing your images, then this will help you immensely. These second or back-up copies ensure you have original un-touched images saved separately from your working images. 


Save them in the location of your choice. (Note that Lightroom will create an additional folder named “Imported on…” and save your images inside.)
