So, I spent some time this afternoon trying to make a video of how I do these macro shots on my dining room table. The video's looked pretty good, but had no sound. So, since I know nothing about video...I guess it was a lost cause.
Anyway, I did come away with a few shots that I can use here as an example of how I can create different images by adjusting the lighting.
I am using a small, LED, video light to light most of my macro images. Sometimes I hold the light in place and snap the photo and other times I place the camera in manual mode with a shutter speed of a few seconds and paint the light where I want it to be. Moving the light and altering the angle of the light greatly effects the final image.
Let's take the below images as examples.
In the above image, I am simply holding the light in my hand, off to the left of camera. You can actually see the reflection of the light in my "water drop", which is actually Karo Syrup.
Now, in this image I have set a longer shutter speed and tried to backlight the front petals while quickly hitting the front side of the flower with the light to show a little detail there, too. Essentially, painting with the light...like I mentioned before.
Both of these images are the exact same composition. They were both shot at F/16 and ISO 100 with the later having a longer shutter speed allowing me to paint the light on,
You can see what a dramatic difference moving the lighting has created.
While I really like the backlit image above, I really think this backlighting works out fantastic for images you plan to create as black & white. In the image below I have used Nik's Silver Efex Pro 2 and converted it to black & white.
Again, same composition and settings, this one was just converted to black & white. Maybe I will have time to try this video thing again in the near future for you to see the process. I may have to consult with a professional, though.
