When you have a lot of similar images from a shoot, you can organizing them using the Lightroom Stacks feature. This allows you to stack images together so that only one image representing the stack appears in the Grid, Filmstrip and Loupe. This can clean up the screen reducing the number of images you see.
To stack images, in the Library module, select the images to stack, right click and choose Stacking > Group Into Stack. This stacks the images on top of each other.
In Grid view you will see a small number in the top corner of the image at the top of the stack showing the number of images in the stack.
