![]() The line from Venus through the target should ideally end up on a flat ‘screen’ wall.ĭespite Venus being such a brilliant planet, its shadow is still dim and will require an extended exposure.Ī mid to high ISO and low f/ number are essential. In a darkened room, attach a shape to a window pane to act as a shadow caster – in this case a cardboard cutout of the symbol of Venus. Credit: Pete LawrenceĪ west or northwest-facing window is ideal for capturing the shadow of Venus. How to do it As Venus is essentially a point source, the resulting shadows all appear sharp when cast on the wall. Then it’s simply a case of pointing a camera at the screen, focusing and taking your shot.Ī high ISO is recommended to keep the exposure times short take too long and the razor-sharp edge of the shadow will blur as Venus moves relative to the horizon. This can be a shape cut from card pasted on a window or suspended in front of the box. You’ll need a shadow-casting subject as well. ![]() This can be as simple as a light-coloured wall or several large white sheets of paper. If you can’t do this, use a large cardboard box with the opening pointed at Venus.Įither way, you’ll need a screen on which the shadow will be cast. Even a bright sky can interfere.Ī west or northwest-facing window is ideal, as long as you can turn all of the lights off. To record the elusive effect of a shadow cast by Venus’s light, you’ll need to be somewhere where there are no other light sources. Venus’s light had to pass through tree branches on the way. You’ll need a DSLR camera with lens, a tripod or, preferably, a tracking mount 3 astrophotography experiments with Venus Photograph a shadow cast by Venus A view out of the window with the shadow-casting Venus symbol attached to the glass. Here are three ways of photographing Venus that you may not have tried before. You can also capture diffraction spikes when photographing Venus, and image the rainbow-like effect of dispersion. When placed in a dark sky, it’s possible to experience Venus’s light casting a shadow – okay, it’s a dim shadow, but it’s one that can be photographed.īeing very close to a point light source, the shadow cast is really sharp and well-defined too. Being so intensely bright – the brightest of all the planets and often referred to as the morning or evening star – it’s essentially a point source at low magnification, and ideal for demonstrating experiments with light. Venus is interesting for another reason too. As shown here with both the Moon and Venus, the spike quality can vary between lenses. ![]() You can produce diffraction spikes by stopping down a camera lens, using Venus as the bright light source. It’s an interesting object astronomically, showing subtle atmospheric markings through the eyepiece, as well as displaying striking changes in phase and apparent diameter. ![]() Venus is well-placed in the evening twilight in April, an intense blaze of light, difficult to miss in clear skies. 3 unique ways to photograph the planet Venus ![]()
