Apply a basic RAW conversion
Import your RAW file into Lightroom by going to the Library tab and clicking Import. Navigate your way to the image you’d like to edit using the Source panel and hit Import. Now change to the Develop tab at the top of the interface. Click on the Lens Corrections panel, and under Profile make sure Enable Profile Corrections is ticked. Click on the Crop Tool and draw a crop over your image. Hit Return to set it in place. Click on the Basic panel to expand it and pull the Exposure slider until your shot looks correctly exposed. You can then set Contrast to +10, Clarity to +10, Vibrance to +35 and Saturation to +5. It’s also worth tweaking the Highlights, Shadows, Blacks and Whites sliders to finesse your contrast.
Above A crop is the easiest way to make your subject larger in the frame so it appears more dominant.
