Some photographers oppose the idea of using flash or light modifiers. Sometimes because it does not suit their style, sometimes because they do not feel comfortable using flash in first place. While we as photographers often love the feel of soft, natural light, knowing how to utilize artificial light can be of tremendous value in low-light environments. Not to mention that such knowledge and being ready to overcome challenging tasks in pretty much any environment can boost confidence and give peace of mind when working in the field. In this article, I would like to go over situations when flash should be used and how it can work to our advantage. I divided this article into indoor and outdoor photography to make it easy for everyone to follow. Please feel free to add your use cases in the comments section below. Please note that I am not going over the basics of flash photography here – the article assumes that you understand the relationship of flash with ISO, Shutter Speed and Aperture.
1.1) Lighting Ballrooms, Churches, Wedding / Corporate Reception Areas
As a working professional, one should have at least the basic lighting plan to be able to capture the day with ease. High-end DSLRs may be flexible enough to capture images in poorly lit environments, but it is a game of compromises. If light levels are too low, you will have to deal with blurry images due to motion blur / camera shake, or you will have to increase ISO level too high, which obviously increases noise, messes up colors and greatly reduces dynamic range. In short, you are leaving very few options for post-processing. In order to avoid that and potentially reduce your post-processing time and other headaches, why not use flash instead? You can start out with a simple configuration, with flash mounted on your camera, or you could get more creative and use flash in an off-camera setup to make images appear more dramatic and well-balanced.
