How to take a silhouette effect with a SLR? How to set the aperture shutter and iso respectively? I feel that the silhouette taken under the fiery red cloud is particularly beautiful.

Expose the background as correctly as possible in the case of positive reflection. If the exposure of the theme is less than 2 pieces, there will be a silhouette effect. As for aperture, shutter and iso, these are all requirements for depth of field and light intensity. Adjust them at any time.

Backlight silhouette figure shooting can actually be regarded as a kind of portrait photography in Gao Fancha. Backlight photography is a silhouette image effect taken by the subject with the light source behind him. In general, the tolerance of photographic film for feeling and expressing hue is very limited. In contrast, human eyes have a much wider range of perception of hue. In this way, on the screen, darker objects can stand out against a brighter background.

When shooting people's silhouette with backlight, sunlight is often used as the light source, but any light can be used as the light source according to the photographer's convenience or preference. It is reasonable to take a silhouette with the sky as the background after sunset or before sunrise. In order to produce good backlight silhouette effect in photos, the ratio of the brightest part to the darkest part in photos is usually 50: 1.
