There are several photography tricks you can use to get a warmer sunsets:
Manually set White Balance (WB) – The thing is that usually sunset colors use lower than average color temperatures, and your camera will try to balance it out if your white balance mode is set to auto. So try to manually set white balance to Daylight at first. If you want even warmer colors, try Cloudy and Shade white balance settings, respectively.
- Try to underexpose a little – Assuming that you underexpose slightly, there is a good chance that your photo might have a little warmer colors in a sunset, however you will still need to fix it in photo editing tool.
- Use warm-up filter – this one is obviously a no-brainer, but it is one of the preferred methods of the pro photographers. Get a warm filter such as Cokin Series P Warming Filter 81A or 81B slide it in the holder and fire away. You might want to use a tripod and a remote release with this technique.
Best of luck, and let us know how it went. Happy shooting!
