It depends on how your model will look in the photo https://www.artlook.us/service/wedding-videography/. With this parameter, you can both ruin everything, and save an initially hopeless picture. There are several tips for shooting in different conditions. I propose to consider some of them.
The first tip is to beware of the bright midday sun if you work outside. As paradoxical as it may sound, too bright sun can damage the picture. Why? It will make the model squint, the shadows on the face will be deeper and sharper, and you can also just get overexposed objects. Therefore, many recommend working early in the morning or in the evening, or on a cloudy day.
Second – try to shoot in the shade if the clear sun caught you by surprise. It is better, by the way, to use the shadow of the building so that it is uniform. As you know, the leaves of trees have small gaps between them, through which unwanted light can enter the model.
Third – if you still can’t find a suitable shade, avoid shooting against the sun. It is impossible for the model to squint, but I don’t want to get a black silhouette either. Therefore, I recommend to become sideways to the sun’s rays: this is how some kind of compromise will be reached.
If you have to shoot against the light, use an external flash in fill light mode. Yes, it is an external flash that should be used in such a situation: the built-in one will definitely not be enough. The same advice will be relevant for shooting at sunset, with the only difference being that our flash will play the role of the main light. Another useful accessory can be a diffuser or reflector.
Once in the studio, everything becomes a little easier. There are a couple of basic rules here, without which it will be very difficult to get an even, high-quality photo. It is necessary to use lighting devices with the same color temperature, use soft diffused light, and also abandon fluorescent lamps.
