This video shows you how to maximize the light at sunset or sunrise when the tints are golden (the golden hour) or even blue (the blue hour). This light is usually soft and forgiving yet very colorful. In order not to overdo the image processing, edits should be really slight.
Add some temperature, lift the tint to the right, and push some contrast and Smart Tone. Image Radiance will also be helpful if you want to make the photo look more romantic and glowing. Color contrast is the final edit that will push colors to the limit and deliver an excellent result.
