In Lightroom Classic it gives you the opportunity to filter through, rate and colour code you imported photos.

Lightroom uses Previews of your photos not the actual photo file its self.

The filing system makes light room less cluttered and easier to find your work.

The photos I like I have flagged them by selecting the photo and pressing p.

To discard the photos I don’t like so I know not to use them I have put black crossed flag on them and it comes up as grey

To colour code my photos i selected the photos in a simple traffic light code in order of photos i like, find okay and photos I don’t mind i did this by selecting the photo then pressing the square on the bottom right hand side and selecting the colour.

I also rate my photos by how much I like them so I know what photos to use.

You are also able to make a folder in collections which you are able to put all the photos of one project into a file so you arent habing to look through thousands of photos to find one project.

you do this by pressing the plus button on the left hand sign of the screen, you then drag the photos into the file.
