ROR is a different kind of cleaner. It is not a lens cleaner in the usual sense. It goes a step beyond routine cleaning. ROR means "residual oil remover" and was specifically designed to emulsify and remove the microscopic film of oil that is caused by environmental pollution. When you cleans a lens with ROR, you will observe a measurable difference in brightness and clarity of your lens. For the first time you will experience pollution free, unimpeded vision.

Beginner tips If you want to be more creative with your DSLR, but still want the camera to control the exposure, try using the P (programme) option, which allows you to alter things like the ISO. The smaller the F number, the larger the aperture. A larger aperture allows more light in to your camera resulting in faster shutter speeds. To achieve shots with blurred backgrounds and a sharp object in the foreground e.g. portrait or flower photography, set your camera to A (aperture priority) and select a wide aperture (low F number - e.g. f2.8). To achieve images that are sharp in the foreground to infinity e.g. - a landscape shot, select a higher aperture - e.g. F11, Remember, the larger the F number, the smaller the aperture, resulting in less light, therefore slowing own your shutter speed, a tripod may be needed. If you don't want to use the flash on your camera in a low light situation, increase the ISO setting, this in effect, increases the sensitivity of the sensor to light, meaning that you can capture low light subjects and still hand hold the camera without motion blur. Remember that increasing the ISO setting does degrade the image, the higher the number, the lower the quality. See the beginner guides section for more information.
