I set up the subject in the light box I had constructed, using a florescent lamp as the light source. I intentionally underexposed the photo while taking it in raw, and then increased the brightness in photoshop. Probably the prevalent principle of design is shape; the shape of the laces, as well as the patterns stitched in the sides of the shoe.
With this pair of sandals, I chose to shoot them from the side in order to emphasize both the buckles and the straps, which lend a sense of movement to the photo because the viewer's eye can follow the lines from left to right. Again, I placed the shoes in the light box in order to create a softer lighting effect.
The contrast between the goldenish inside of the slipper and the stark black outline was very appealing to me, and I wanted to try and bring that out more in the photograph. Thus, I positioned the two slippers in such a way so the dichotomy between the two colors would be most apparent. So, it goes without saying the principle I focused on in this photograph was color contrast. Besides that, my process was the same; I still photographed the shoe in the cardboard light box.
Tonal value, the slow shift from light to dark, was an important aspect to this photograph. I purposefully underexposed the photo while shooting, so I would have a wider range of tones to play with in photoshop. I especially liked the highlights on the buckles, something that could only be achieved because I was using a florescent lamp in combination with a light box.
I only slightly edited this picture in photoshop (increasing the color saturation fiddling with the hue and color balance, and a little bit with the color contrast) but the picture actually came out like this on my camera. I had too slow a shutter speed, coupled with a wide-open aperture, that consequently let in far too much light, overexposing the picture. But I really liked the result, the exposure added a surreal quality to an everyday subject. And the color scheme worked well, they were all analogous colors.
