High Speed Pictures


Is it possible to take high speed pictures with your ordinary DSLR, like my Nikon D60?

Out of my 500 pictures, see my selection of 2 pictures. The water was red colored with a red background, so no color adjustment was made.



My amateur studio.... two tripods, paint, water, background and light.

Those migrations could explain the existance of the Kuiper belt, the Oort cloud but also the late heavy bombardment.
