37 The Lighting Angle


This exercise requested a number of lighting angles of a still life subject all with a diffused light source. The first was with the light level to the subject, moving from the camera position to almost behind (160 degrees, see diagram) then fully behind (silhouette). The second was the same positions but one with the light looking down to the subject at a 45 degree angle. The third was with the light source above the subject, positioned behind, over and then in front of the subject.

Equipment used, Nikon DSLR, 105mm lens, tripod, black background and lighting stand. Processed using Nikon NX2 and DXO.

I chose a carved wooden ornament of a man and women embarrassing, the only location I had that had enough area around it was the light marble kitchen work top. Which in hindsight has acted as a reflector for the higher lighting angle shots and I should have covered it with some black paper, but it has not materially affected the value of the results.

Lighting level with subject

Front

DSC_5356_DxO

This is the flattest lighting of the series, with a diffuse light from the same position as the camera. Yet it would yield a reasonable portrait, especially if a single person lit with a ring light.

45 degrees side

DSC_5357_DxO

With the lighting now at an angle to the subject, the shadow creates a more three dimensional appearance.

90 degrees side

DSC_5358_DxO

As the lighting comes to the 90 degree angle more surface detail is visible. This may be desirable for some shots and not for others. The image here certainly takes on a very three dimensional aspect due to the shadows cast over the subject. Even with a diffuse light source the shadows are quite dark at this angle, a reflector on the left side could be used here to bounce back some more light into the shadow. This would be my personal preference for showing 3D properties of the subject.

135 degrees side

DSC_5359_DxO

Shadow now pronounced on unlit side, but surface detail and ‘blemishes’ clearly visible on lit side.

160 degrees

DSC_5360_DxO

Now with the light as close to behind the subject as possible, without appearing in background. Again a lot more detail of the lit surface area is visible at this angle.

180 degrees (behind) clearly creating a silhouette

DSC_5362_DxO

Gives a clear outline of the subject, but no detail what so ever.

180 degrees (behind)

DSC_5370_DxO

This series at 45 degrees down has similar qualities to the first set with more downward shadows due to lighting angle.

DSC_5374_DxO

Very ‘The God Father’ (Marlon Brando office scene) where the lighting technician nearly got fired because you could not see their eyes, but made for a very dramatic and powerful part of the movie. All three shots show good surface detail of the subject.
