Using a combination of a ringflash, gels, a macro lens and a low-sensitivity film you can create some amazing close, colourful and high-contrast photos. Using slide film and cross-processing launches these photos into full on psychedelia.
I discovered this process by accident, but have become addicted to the results. I recently purchased a ringflash and close-up lens for my Diana F+ camera. My plan was to walk to some antique stores an hour from my house and hunt down some interesting photo opportunities. I purchased some Lomography 200iso X-Pro Slide Film to use. Not ten minutes from my house it began to rain and all available light disappeared, along with my desire to keep walking. I peeled off my lens cap and took some quick up-close photos of a nearby flower bed and dashed home. When I had these developed they looked like night time shots due to the low sensitivity film. The background disappeared into darkness, but the flash brought insane colour and texture to the foreground objects.
The next round of shots were cross—processed and from there I have never looked back.
