Project 58; Contrast and shadow fill.

This photo was taken as instructed in the course notes. I positioned the light source (a speedlite) on the viewers right of the frame. The light source was used without a diffuser and I used a flash meter to set the exposure which was F16 and 1/250th second. Without doubt this is the photo with the strongest contrast in the series. The shadows are very dark and the highlights are very bright.

This is the second in the series, the light source is in the same position but this time I have used a diffuser positioned just outside the frame and as close to the subject. The exposure was checked first with a flash meter and was 1/250th of a second and F8. the amount of diffused light that leaks around the subject is clear to see in this shot.

Here I have used the same exposure as the first shot and placed a white reflector 3 feet on the other side of the subject and opposite the light. This has filled the shadows.

Same exposure, naked light source and white card reflector moved to within 1 and 1/2 feet to the opposite side of the light, again the shadow fill is easy to see and more than the previous photo.

Exposure 1/250th of a second and F16. Light source is one undiffused speedlite 3 feet to the right. Shadow fill here is achieved using the duller side of a piece of tinfoil. Interesting, the shadow fill is uneven compared to the previous shot with the white reflector. There is hardly any shadow fill on the bowl, now this could be because of the position or angle of the reflector.

Exposure is as noted for the previous photo, the light source has not changed. The only thing that has changed is the reflector. This time I am using the shiny side of the tin foil. The shadow fill is greater, the greatest amount so far.

The only thing I have changed here is the reflector. The tinfoil has been crumpled and then straightened out. The shadow fill is again different and more like the white card. The difference between this and the previous shot is that the shadow fill is more even, more diffused perhaps? comparing this last shot to the white reflector, the white gives a more even shadow fill.

Here I have used a gold covered reflector. The shadow fill is less.

Here I have placed the light behind the subject to get a silhouette, I wanted to compare this with the next few shots.

Same exposure but this time using a grey reflector behind the lens to give a little shadow fill.

Here a dull silver reflector has been used to give more shadow fill.

Here I have used the tinfoil again crumpled. Nice shadow fill, not too much.

Here I have used the light source on the right and a black piece of clothe on the left to darken the shadows. I can see very little difference between this and the first shot in the series.
