Lightroom is a great photo editor that allows you to apply filters to your photos. You can use filters to change the look and feel of your photos, as well as add a touch of color. To apply a filter, open Lightroom and click on the filter button in the top left corner of the main screen. You will see a list of filters available, with each one listed in order from most important to least important. The first filter on the list is called “Photo Filter.” This is the default filter for Lightroom. To apply it, click on it and then select the type of photo you want to add a filter to. For example, if you want to add a color filter, then select “Photo Filter: Color.” Once you have selected a photo for a filter, click on the OK button in the bottom left corner of the main screen. The photo will now be filtered with that filter applied. If you want to remove any filters from an image, simply click on one of the buttons at the bottom of the main screen and then select “None” from the drop-down list next to that button.
