Reflected Light Spot Metering

The Sekonic L-758D incorporates a precise 1-degree, reflected light spot meter. Reflected light metering tells you about the subject. Different from incident light metering that produces readings only for the middle of your camera’s exposure range, reflected light metering can also show you where the edges are. The key to working with the L-758D’s spot meter is knowing the dynamic range of your camera. That is, the tonal range your camera is capable of recording. Program this into the L-758D and you can easily know which details will be properly imaged and which will be over or under the range of your camera. Armed with this knowledge, you can make exposure decisions that take full advantage of your camera’s imaging capabilities to produce pictures with greater tonality and clarity than you have

Incident Light Metering

Incident light readings are, in fact, the simplest and most direct way to determine exposure. And because incident meters measure the light that falls on your subject, they provide camera settings that render the image exactly the way it appears. Blacks are black. Grays are gray. Whites are white.

Retracting the Sekonic L-758D’s Lumisphere enables you to quickly judge the brightness of multiple light sources for fast, accurate adjustment of lighting ratios.

Digital Photography: Boundless Possibilities

Today’s High Dynamic Range (HDR) processing enables breaking through the limits to produce results never seen before. Knowing your camera’s capabilities and precise exposure readings with the L-758D will help you make right exposure settings and save you time in processing. The picture of this Mexican plaza and church was created shooting multiple images (below) and "merging" them in HDR processing to create the image on the right.
