UV test




Here we have experimented with shooting in Ultraviolet in preparation for our shoot. To do this we used a converted full spectrum DSLR, and placed a UV pass filter on the lens which blocks out all wavelengths of light except for UV light. Sunlight is the most available free UV radiation source for use in reflected UV photography, but the quality and quantity of the radiation depends on atmospheric conditions. A bright and dry day is much richer in UV radiation and is preferable to a cloudy or rainy day. Our result reflects this as the sunlight wasn't particularly strong, therefore causes the image to not be sharp and detailed. We need to make sure that the presence of the sun is strong in order to manage considerable results. We considered doing a studio shoot but we were unable to gain access to UV lights or flashgun. We also found using the DSLR quite temperamental as we weren't able to look through the view finder or camera's live view function, due to the filter on the front which blocked visible light from reaching our eyes. This resulted in a lot of trial and error and guess work.
