This time of the year, especially along the east coast of Australia, there are usually plenty of fungi to photograph, due to the combination of rain and heat.  Fungi generally look better when photographed without flash, so using a tripod is essential in low light conditions such as dense rainforests.  As well as a tripod, I also recommend using either a remote or cable release (or self timer if you don’t have either) as this further minimises any movement caused from manually pressing the shutter.
 
For digital SLRs, “Live View” is also a great tool to use.  This allows you to see your subject, zoom into it, manually focus and then take the shot.  Mirror Lock-up is also a great feature on SLRs.  This allows your mirror to open on one press of your shutter button, lets it settle and then you can press the shutter again and you have taken a shot without any mirror movement.
 
Lastly, try and photograph fungi when the weather is grey and overcast as this provides a great natural “diffuser” that reduces blown highlights.
