We are able to, but no, we won’t do fake skies / sky replacements/ sunset skies or artificial night time scenes and there’s a reason, actually several.
First, they look fake. It doesn’t really matter how “real” you think they look, they still look fake. The human eye knows there’s something “off” about the picture. Usually it’s the shadows or lack of them. On sky replacements, they’re usually done to take care of cloudy skies. The problem is when the sky is replaced, now you have a mostly clear, sunny sky – but no shadows on the ground. It’s unnatural and your viewer’s eyes know it, even if they don’t consciously realize it.
Secondly, sky replacements, especially night-time or sunsets produce a product that will never be experienced by the person renting or buying the property. We’ve even seen some that produce an atmospherically impossible “northern sunset”. The prospective buyer or renter is being sold an experience they’ll never have and we can’t ethically take part in it.
Third, there’s a legal risk created by doing more than color correction on real estate photos. If the renter/buyer is sufficiently misled, they may have legal recourse.
For these reasons, unless it’s for personal use or residential/commercial art, we ask that you use another service for photos needing these features.
