TIPS FOR USING THE VELLO EXTENSION TUBES
• As with all macro photography, images will have a very shallow depth of field.
To increase the depth of field, select a smaller aperture.
• Due to increased exposure times, a tripod and cable release or remote control
are always recommended for macro photography.
• Closer focusing can be achieved by using the larger extension tubes or by
stacking the tubes.
• Due to the increased distance between the lens and the sensor, the camera’s
TTL system may not always be accurate. Use a manual exposure mode if this
happens.
