For this assignment you will draw together some of the different lighting skills that you have been studying.
Choose an object and take a series of images to show its
So I wanted some items with colour, texture, nice shaps and just a little different. Well here is what I chose.
The image, as you can see is of two medals. You can see the nice round shape, the ribbon holder and the ribbon, but you can NOT see a great deal of detail on the face of the medals. The colour of the medals/ribbons are not clear.
I had to make up a small lighting box for this image. After cutting a hole in the side I place a white light behind and then experimented with different colours of paper. The white balance was set to Tungsten.
In the end I used a piece of thin white fabric , with lighting from behind. I tried a flash gun (Off Camera) but I did not like the results. I also tried to get a similar result with natural light but the effect was poor.
My first set of test shots had one light but I changed my mind and then put a smaller light behind each medal to show a nicer effect.
The next image had to show form or volume. I had to get the medals to stand out from the background. Even though they were small I had to try to show the thickness of the metal to give impact to the image. I think that moving the camera down and placing one medal on top of the other helped to do this.
You can see, I hope, that the medals are made from solid pieces of metal. Shooting with the flash off camera to the right of the lens on F22 gives nice depth of field on the medals with the ribbons just going out of focus.
You can also start to see more detail on the face of the medal. I also saw that I could pull up further detail (ie my name on the side ) if I changed the position of the flash. This discovery helped me in the next section, Texture.
Images 3 and 4
Even though the metal appears to be smooth on each medal there are raised letters and other details that I had to capture.
I fitted a diffuser to the flash so I could reduce glare . White light was ok but the medals looked flat, with no apparent scratches on the gold medal. The letters were shown as raised but they were not great. With the assistance of two coloured filters I managed to get these two images.
The green filter really brings out the raised letters and other details on the surface. You can see the small scratches on the face of the medal.
However I think that the orange filter shows up more detail on the gold medal.
Here are to crops of images taken with and without the orange filters. Both images taken at iso 200, with handheld off camera flash.
There are clear differences between the surface markings on the gold medal. It really did surprise me as to how the two images ended up.
In view of this I decided later to see how changing an image to black and white would affect the surface detail:-
You may be able to see that the letters are clearer on the right medal, but the scratch are less visible.
The next task was to show the colour of the items.
For these images I was lucky that the sun came out so I set up a black section of board on a chair , on the patio. The sun was very bright, but the clouds were causing problems so I reverted to plan B which was leave the medals outside and use an electric lamp. The first pictures I took were terrible, I then realised that I need to diffuse the light, so with a single white paper tissue over the light I captured this image.
You can see the strong colours of the ribbons especially the red stripes. The medals are a nice colour and there is even a nice silver/gold reflection on the black board.
So in this exercise I used
- Tungsten lighting from the rear with a diffuser.
- Tungsten lighting from the front/side with a diffuser.
- Off camera flash with white diffuser.
- Off camera flash with green filter in front of the diffuser.
- Off camera flash with orange filter in front of the diffuser.
- Camera on a tripod in order to use the lowest iso I could to improve image quality (Iso 200)
