When sunlight travels through certain elements (such as a cloud, fabric, or paper), it loses intensity and diffuses. The light hits the subject by way of smaller rays that do not follow a straight line but disperse in space, creating a completely different effect from that of a hard light. In this case, the shadows are much softer and diffused. The contrast is also a lot less sharp, and it is difficult to distinguish where the light and shadows start and end. In comparison with a hard light, a diffused light has a bluer tone, and, of course, the light intensity is a lot lower when we use diffusers to take photos.

Learn essential techniques to create lifelike self-portraits by understanding light, shadow, and form When it comes to creating realistic drawings, understanding the relationship between light and shadow is crucial. Whether you’re an aspiring artist or a seasoned creator, mastering these principles will elevate your artwork, bringing depth and dimension to every piece. In this tutorial, visual artist Gustavo Ramos shares his step-by-step approach to capturing the nuances of light and shadow through a simple sphere exercise. This foundational practice can prepare you for more complex projects like self-portraiture.

Hard-edged shadows are the defining characteristic of a hard light; in a photograph with hard lighting, it is easy to tell where a shadow starts and ends. There is also a high contrast between the very brightly lit up areas and the shaded ones.

There are various ways to compensate for overly hard lighting that could negatively impact your desired result. You can move your model and ensure that the hard light works in your favor. Otherwise, if you want to diffuse the light, use a simple piece of material, such as a bedsheet, as a diffuser. Remember to adjust the diaphragm or the shutter speed. Open the diaphragm and lower the shutter speed for shoots in diffused light conditions and do the opposite for shooting in hard light.

Sometimes, it may be impossible to control lighting conditions, for example, when natural light fluctuates. In those cases, we need to find a way to take our pictures and still get a good result. A photographer needs to know how to compensate for the exposure and create an image that it is not over or underexposed.

In photography, natural light is the most unpredictable element when we set up for a shoot. Until we are behind the camera, we cannot be sure what type of lighting we’ll be working with, so we need to know how light affects the scene.

In a hard light photo, the light is mostly white or has a very characteristic warm tone. The light intensity is also higher: the presence of so much light and shadows clearly shows the light source's impact.
