Make sure your photos are in a thumbnail format before screenshotting.

screenshot your photo thumbnails and open the image onto photoshop.

select the brush tool and use colours and lines to show what photos you are going to use, which ones you are going to discard etc…

You should end up with something like this…

Green box – using

red stroke – not using

green question mark – not sure to use as final

red question mark – not sure wether to use at all

horizontal lines – cropping
