Either from the slit in the front of the tent or by pulling back the
Velcro strips along the top of the front. If you can blur the white tent
as background it works well for some subjects. Larger light tents
give you more freedom in this regard but are even more awkward
to move around.
I find that using light tents is well worth the extra effort and hassle
involved. And the larger (48”) tent can be used in a field of flowers
or plants, placed over an entire section allowing you not only to
work with plants but to remove the wind factor on the top of plants
(like Queen Anne’s Lace) and concentrate on the many interesting
insects that are wandering around on the flower heads. Moving
insects AND moving flowers due to wind usually manage to make
any stacked photo almost impossible but remove the wind and the
insects may pause long enough to get some depth from stacking a
few shots.
